b) 值类型和引用类型；
c) 引用类型和关系类型；
d) 关系类型和调用类型；
2. int[ ][ ] myArray3=new int[3][ ]{new int[3]{5,6,2},new int[5]{6,9,7,8,3},new int[2]{3,2}}; myArray3[2][2]旳值是（ ）。

3．如下旳C#代码，试图用来定义一种接口：

int delFile()
{
A = 3;
}
void disFile();
}
有关以上旳代码，如下描述错误旳是（）。
a) 以上旳代码中存在旳错误包括：不能在接口中定义变量，因此int A代码行将出现错误；
b) 以上旳代码中存在旳错误包括：接口措施delFile是不容许实现旳，因此不能编写详细旳实现函数；

二．选择题（英文）
6.You use Visual Studio .NET to develop a Windows-based application. Your application will display customer order information from a Microsoft SQL Server database. The orders will be displayed on a Windows Form that includes a DataGrid control named DataGrid1. DataGrid1 is bound to a DataView object. Users will be able to edit order information directly in DataGrid1. You must give users the option of displaying only edited customer orders and updated values in DataGrid1. What should you do?
A: Set the RowStateFilter property of the DataView object to DataViewRowState.ModifiedOriginal.
B: Set the RowStateFilter property of the DataView object to DataViewRowState.ModifiedCurrent.
C: Set the RowFilter property of the DataView object to DataViewRowState.ModifiedOriginal.
D: Set the RowFilter property of the DataView object to DataViewRowState.ModifiedCurrent.
7.Another developer in your company uses Visual Studio .NET to create a component named MyComponent. You deploy MyComponent to a server. When you execute MyComponent, you receive the following error message: "System.Security.Policy.PolicyException: Failed to acquire required permissions." As quickly as possible, you need to discover which permissions are required by MyComponent. What should you do?
A: Request the source code from the developer who created MyComponent. Examine the source code to find the required
permissions.
B: Run the Microsoft CLR Debugger (DbgCLR.exe) on the server to view the permissions requested by the application at run time.
C: Run the Runtime Debugger (Cordbg.exe) on the server to view the permissions requested by the application at run time.
D: Run the Permissions View tool (Permview.exe) on the server to view the permissions required by MyComponent.
E: Run the MSIL Disassembler (Ildasm.exe) on the server to view permission requests by MyComponent that were denied.
8.You use Visual Studio .NET to create an application. Your application contains two classes, Region and City, which are defined in the following code segment. (Line numbers are included for reference only.)
01 public class Region {
02 public virtual void CalculateTax() {
03 // Code to calculate tax goes here.
04 }
05 }
06 public class City:Region {
07 public override void CalculateTax() {
08 // Insert new code.
09 }
10 }
You need to add code to the CalculateTax method of the City class to call the CalculateTax method of the Region class. Which code segment should you add on line 08?
A: CalculateTax();
B: this.CalculateTax();
C: base.CalculateTax();
D: Region r = new Region();
r.CalculateTax();
9.You use Visual Studio .NET to create an application that uses an assembly. The assembly will reside on the client computer when the application is installed. You must ensure that any future applications installed on the same computer can access the assembly. Which two actions should you take? (Each correct answer presents part of the solution. Choose two.)
A:Use XCOPY to install the assembly in the global assembly cache.
B:Use XCOPY to install the assembly in the Windows\Assembly folder.
C:Create a strong name for the assembly.
D:Precompile the assembly by using the Native Image Generator (Ngen.exe).
E:Modify the application configuration file to include the assembly.
F:Use a deployment project to install the assembly in the global assembly cache.
G:Use a deployment project to install the assembly in the Windows\System32 folder.
10.You use Visual Studio .NET to create a component named Request. This component includes a method named AcceptRequest, which tries to process new user requests for services. AcceptRequest calls a private function named Validate.
You must ensure that any exceptions encountered by Validate are bubbled up to the parent form of Request. The parent form will then be responsible for handling the exceptions. You want to accomplish this goal by writing the minimum amount of code.
What should you do?
A: Use the following code segment in AcceptRequest:
this.Validate();
B: Use the following code segment in AcceptRequest:
try {
this.Validate();
}
catch(Exception ex) {
throw ex;
}
C: Use the following code segment in AcceptRequest:
try {
this.Validate();
}
catch(Exception ex) {
throw new Exception("Exception in AcceptRequest", ex);
}
D: Create a custom Exception class named RequestException by using the following code segment:
public class RequestException:ApplicationException {
public RequestException():base() {
}
public RequestException
(string message):base(message) {
}
public RequestException(string message,
Exception inner):base(message, inner) {
}
In addition, use the following code segment in AcceptRequest:
try {
this.Validate();
}
catch(Exception ex) {
throw new RequestException("Exception in
AcceptRequest", ex);
}
