7、昕王立娟 职 称高工讲师 所在单位 信息科学系软件工程教研室 教研室主任 刘瑞杰 完成日期2012年4月13日. NET Generics. NET genericsWhen using the. NET generic types, the most common problem occurs when you need to work with the appropriate type. In the implementation of IWorksheet interface, it is necessary to implement AssignCellState () method

8、defined in the interface IWorksheetSerialize. The question now is, as a parameter in the function of a type of access is assigned to CellState, this is another uncertainty. NET generic type of the distribution, the code looks so simple, but actually cover a lot of potential the problem. Here the par

9、ameter value is of type object. Then, the transformation parameters is the basic type, because this is CellState defined type if the value is correct, this code will work properly.The work is called a variable of type double. When the method AssignCellState () is called Model 1, Model 1 is to specif

10、y the input string. Call AssignCellState () is not a problem, but in the implementation of the conversion will fail. Of course, this avoided the question: Why is there a function type object? Sometimes you can not get anything on these issues, you need to write a general object of the method. Bold c

11、ode that buffer Double.Parse () method to convert a double value to a string buffer. Of course, the conversion will fail, because the string buffer represents some, this is another issue.Another way to solve the problem completely is to avoid the objects and methods as a. NET common method. Advantag

12、e of. NET generics is that you can perform in, type-safe way to force users to perform analysis without a clear program.This code is very clever because it uses so-called reflection, to determine if the type can be assigned to another type. You can try to do so, if there is no statement, but you unn

13、ecessary risk. If allowed to convert, then the conversion will be done by doing two steps:Here, we first convert type object, and then convert a primitive type, which is exactly the type of spreadsheet reporting. This is absolutely necessary to add, otherwise, C # compiler will complain that it woul

14、d be impossible. However, assuming that the type can not be directly allocated. Let us say, the reference to a string that contains a number. Then, by using reflection, you can identify which value types and basic types.The first part, if the value is a string type. The second part asks the two can

15、be assigned to the appropriate type. If both are valid, which means that input is a string, and measure the type, then converted, you only need to call Double.Parse (). Automatic conversion feature does not save the code, generally do not need to worry about the most common conversions, such as they

16、 will happen automatically. Of course, this assumes that you have performed the most common conversion. For those who convert, not to be unusual, as the original based on AssignCellState () object will throw an exception. Overall, AssignCellState () with the. NET provides a generic parameter values,

17、 imagine ways to perform with the maintenance of a conversion. This goes back to the original request, can be safely mixed type.In order to implement the IEnumerable interface, you need to perform the IEnumerable interface. These two interfaces have a single method, only the difference between the t

18、wo is the return type, this is the beginning.Programming languages such as C # does not allow you to overload the method only in the return type is different.This class has two implementations of the Count (), which only return types. This code is illegal because the compiler can not distinguish whi

19、ch method will be required. The following code illustrates the problem of the decision.When performing IEnumerable interface, it is necessary to distinguish which interface methods are implemented, these two methods to do the same thing. So, you must perform a GetEnumerator (), then there are other

20、do the actual implementation.All of this sounds complicated, but it shows the type of problem, you can use to run. NETs common code base, need to integrate the code, do not use NET-imitation.With the interface and comprehensive, it is possible to use a spreadsheet. That the sample application is a s

21、preadsheet to calculate the average of a set of numbers, each number and then how to calculate the average.The next step is to specify the Lambda expression will be used to calculate the average then the average level of individual differences. When you specify a calculation, you need to know whethe

22、r the Lambda expression. Keep in mind that there are some state Lambda expressions. This is just asking if you want to share a state or individual state Lambda Expressions Lambda Expressions. Lambda expressions for the average, a shared state is acceptable.In order to calculate the average of the av

23、erage use of technology to the last element of the array in a series of calculations. Therefore, when the average demand, which I do not know how many, because in the banks average storage.Calculation depends on counting the number of items. Each calculation is assigned to a Lambda expression Lambda

24、 expression which means that all models will be the same state. The only shared variable is items.Length. Lambda expressions expect all the same length, so it is acceptable to share this variable. The calculated average difference to calculate the mean, and then subtract it from the worksheet cell.M

25、odel calculations, because spreadsheets have the ability to track what has been calculated not calculated. In a typical spreadsheet, you can change the model of all miraculously re-calculated. There is no such function, this spreadsheet. However, this simple version of the dependency can be sure tha

26、t they not be counted multiple times.Look back at the source code to calculate the difference between the average. The only reason, the calculation of the work is used with the model known as the average Calculate () method. If GetCellState () method is called, the average may not be calculated, whi

27、ch calculated the difference will be damaged. However, the average per unit, a small change is a waste of resources, because the changes may not affect the model recalculated. To avoid this, the built-in electronic form is a version control mechanism, the model calculates the latest version. Then, i

28、f the calculation is the same as the version number. The following is a Worksheet version number management.Call the Calculate () method takes no parameters that want to recalculate the entire spreadsheet. Then each model iteration, if it exists, Calculate () in the form of (Calculate () parameter)

29、is called the individual model. In the individual model Calculate () in the form, check to see if the model is the latest version number of the calculation spreadsheet; If not, the model is called Lambda expressions.It does not matter the scope of this book. In fact, computing and its side effects a

30、re important. With Lambda expressions, you have a form of asynchronous processing. That calculation does not know when they will require, they can not assume the state. Therefore, when a Lambda expression is established when the state, Lambda expressions may be different when, Lambda expressions are

31、 executed. If you are not keenly aware of the potential pitfalls, you can have some major flaws in your code.In this chapter, you learned how to use. NET generics, but also to expand your knowledge of lambda expressions. Main items to remember are as follows:. NET generic code can use. NET generics

32、provide. NET-based generic type. Examples of this chapter that the use of the code, there. NET generics code processing.Write. NET generics code requires some forethought, because you intention is to create an abstract implementation.You can use. NET generic type level or at the method level. With.

33、NET generic type of class means in the specific type, the type of instance. With. NET on a generic way to mean a specific type.lambda expressions, as they are implemented, the joint state of the state or individual, depending on how they apply and manipulate.For complex types, you should always impl

34、ement ToString () as a clear state of a type. Here are some exercises, allowing you to use your lessons so far:1, Worksheet class always requires you to level before the fixed model arrays. The code changes so that the rows and columns can be changed dynamically. Remember, focus on performance, the

35、fastest way is a fixed three-dimensional array.2, the average know how many items have sequential numbers. Rewrite the average code, so the average user does not need to code the complexity of the transaction to add more content and more.3, Calculate () and GetCellState () method seems to do the sam

36、e thing. Therefore, there is need for a separate method? Answer this question, then make any necessary changes to the source code.All the examples in the previous chapters have shown how to use a specific part of the application. Do you know what type of instance, the interface to use. In this case,

37、 you as a developer, complete control, when your application is built, all the parts up as a nice, neat package. However, the projects development does not necessarily work for others. Lets go back to Chapter 8. We have created a kernel, responsible for turning on and off. In the realization of the

38、individual in a predetermined specific name. This architecture will not be with the third-party libraries, as expected some of the core components of the name. You may be thinking: section, it is very easy to solve, I just delete the old and re-named to match the new name. This technology will work,

39、 but it will also be a system administrators nightmare. That solution is to tell the program, and plans to this information, you determine the number of text files. File to tell a program to do some work is called the running configuration file. This chapter focuses on two areas: Using application c

40、onfiguration file and dynamically execute code. A related issue is how much the dynamic execution of code should be configured and how many conventions.How to reference instance. Consider the structure shown in Figure 12-1, which is a modular interface and implement it as an alternative system, for

41、example, in Chapter 8. In this figure, each square represents an assembly: assembly, which contains the interface definition, assembly, including the implementation, and the assembly that contains the kernel of the idea, all of these components is to make it possible to update one without having to

42、update all of. However, the fact that the picture shows what is not, your application must be able to refer to all three components. If one of these components is missing, you have a problem because you can not run.In light of the individual is not a problem. The question is how each assembly. In th

43、e previous chapter, I said, you should use a factory because the factory is the implementation of the decision taken to use. Let us look at the code in this perspective. Suppose the following interface definition is one that contains all the interface definitions.In the case of run-time configuratio

44、n, the structure shown in Figure 12-1 is not changed, it is still some definition, implementation, kernel and user components. What changes is how to create a reference to each fragment.Lets start with a simple situation. Do you have a problem, you all know who will know the answer. You know, you kn

45、ow she had a telephone. You do not know her phone number. Translation of programming point of view, telephone as an interface to implement. The challenge is to connect to the execution. For the telephone, you can find phone numbers you can find the phone book.In the phone book contains the names of

46、individuals in the specific address and their telephone number. It is easy to remember name and address; phone number is a complex. Therefore, the purpose of cross-referencing a phone book data, more complex information. In the planning of cross-referencing is a configuration file,. NET applications

47、, once you have a cross-reference information, the location of your assembly, and then cross-reference type instance. In planning, the configuration file location and name you type.Configuration file is useful, but they can become too complicated. Some projects have such complex configuration file, an error occurs due to improper configuration application. Convention framework attempts to simplify complex book, a familiar pattern of the reference type. Imagine a phone number 1-800-BIG-CARS-1 and 800 is easy to remember, this is a major project. Because the Convention has
