c#远程控制服务.txt丶︶￣喜欢的歌，静静的听，喜欢的人，远远的看我笑了当初你不挺傲的吗现在您这是又玩哪出呢？在.net中提供了一些类来显示和控制Windows系统上的服务，并可以实现对远程计算机服务服务的访问，如System.ServiceProcess命名空间下面的ServiceController 类，System.Management下面的一些WMI操作的类。虽然用ServiceController可以很方便的实现对服务的控制，而且很直观、简洁和容易理解。但是我认为他的功能同通过WMI来操作服务相比，那可能就有些单一了，并且对多个服务的操作可能就比较麻烦，也无法列出系统中的所有服务的具体数据。这里要讲的就是如何使用System.Management组件来操作远程和本地计算机上的服务。

WMI作为Windows 2000操作系统的一部分提供了可伸缩的,可扩展的管理架构.公共信息模型（CIM）是由分布式管理任务标准协会（DMTF）设计的一种可扩展的、面向对象的架构，用于管理系统、网络、应用程序、数据库和设备。Windows管理规范也称作CIM for Windows，提供了统一的访问管理信息的方式。如果需要获取详细的WMI信息请读者查阅MSDN。System.Management组件提供对大量管理信息和管理事件集合的访问，这些信息和事件是与根据 Windows 管理规范 (WMI) 结构对系统、设备和应用程序设置检测点有关的。

但是上面并不是我们最关心的，下面才是我们需要谈的话题。毫无疑问，我们要引用System.Management.Dll程序集，并要使用System.Management命名空间下的类，如ManagementClass,ManagementObject等。下面用一个名为Win32ServiceManager的类把服务的一些相关操作包装了一下，代码如下：

using System;
using System.Management;
namespace ZZ.Wmi
{
public class Win32ServiceManager
{ private string strPath;private ManagementClass managementClass;public Win32ServiceManager():this(".",null,null){
}
public Win32ServiceManager(string host,string userName,string password)
{this.strPath = "\\\\"+host+"\\root\\cimv2:Win32_Service";
this.managementClass = new ManagementClass(strPath);if(userName!=null&&userName.Length>0)
{
ConnectionOptions connectionOptions = new ConnectionOptions();connectionOptions.Username = userName;
connectionOptions.Password = password;
ManagementScope managementScope = new ManagementScope( "\\\\" +host+ "\\root\\cimv2",connectionOptions) ;
this.managementClass.Scope = managementScope;
}
}
// 验证是否能连接到远程计算机
public static bool RemoteConnectValidate(string host,string userName,string password){
ConnectionOptions connectionOptions = new ConnectionOptions();connectionOptions.Username = userName;
connectionOptions.Password = password;
ManagementScope managementScope = new ManagementScope( "\\\\" +host+ "\\root\\cimv2",connectionOptions) ;
try
{
managementScope.Connect();}
catch
{
}
return managementScope.IsConnected;}
// 获取指定服务属性的值
public object GetServiceValue(string serviceName,string propertyName){
ManagementObject mo = this.managementClass.CreateInstance();mo.Path = new ManagementPath(this.strPath+".Name=\""+serviceName+"\"");return mo[propertyName];}
// 获取所连接的计算机的所有服务数据
public string [,] GetServiceList()
{
string [,] services = new string [this.managementClass.GetInstances().Count,4];int i = 0;
foreach(ManagementObject mo in this.managementClass.GetInstances())
{
services[i,0] = (string)mo["Name"];services[i,1] = (string)mo["DisplayName"];
services[i,2] = (string)mo["State"];
services[i,3] = (string)mo["StartMode"];
i++;
}
return services;}
// 获取所连接的计算机的指定服务数据
public string [,] GetServiceList(string serverName)
{
return GetServiceList(new string []{serverName});}
// 获取所连接的计算机的的指定服务数据
public string [,] GetServiceList(string [] serverNames)
{
string [,] services = new string [serverNames.Length,4];
ManagementObject mo = this.managementClass.CreateInstance();
for(int i = 0;i<serverNames.Length;i++)
{
mo.Path = new ManagementPath(this.strPath+".Name=\""+serverNames[i]+"\"");
services[i,0] = (string)mo["Name"];
services[i,1] = (string)mo["DisplayName"];
services[i,2] = (string)mo["State"];
services[i,3] = (string)mo["StartMode"];
} return services;}
// 停止指定的服务
public string StartService(string serviceName)
{ string strRst = null;
ManagementObject mo = this.managementClass.CreateInstance();mo.Path = new ManagementPath(this.strPath+".Name=\""+serviceName+"\"");
try
{if((string)mo["State"]=="Stopped")//!(bool)mo["AcceptStop"]mo.InvokeMethod("StartService",null);
}
catch(ManagementException e){ strRst =e.Message; }
return strRst;
}
// 暂停指定的服务
public string PauseService(string serviceName)
{
string strRst = null;
ManagementObject mo = this.managementClass.CreateInstance();mo.Path = new ManagementPath(this.strPath+".Name=\""+serviceName+"\"");
try{
//判断是否可以暂停
if((bool)mo["acceptPause"]&&(string)mo["State"]=="Running")mo.InvokeMethod("PauseService",null);}
catch(ManagementException e){
strRst =e.Message; }
return strRst;}
// 恢复指定的服务
public string ResumeService(string serviceName)
{
string strRst = null;
ManagementObject mo = this.managementClass.CreateInstance();
mo.Path = new ManagementPath(this.strPath+".Name=\""+serviceName+"\"");
try
{
//判断是否可以恢复
if((bool)mo["acceptPause"]&&(string)mo["State"]=="Paused")mo.InvokeMethod("ResumeService",null);}
catch(ManagementException e){strRst =e.Message;
}
return strRst;}
// 停止指定的服务
public string StopService(string serviceName)
{ string strRst = null;
ManagementObject mo = this.managementClass.CreateInstance();
mo.Path = new ManagementPath(this.strPath+".Name=\""+serviceName+"\"");
try
{//判断是否可以停止
if((bool)mo["AcceptStop"])//(string)mo["State"]=="Running"
mo.InvokeMethod("StopService",null);
}
catch(ManagementException e)
{
strRst =e.Message; }
return strRst;
}
}
}
