WMI 远程控制服务

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+" ootcimv2: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+ " ootcimv2",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+ " ootcimv2",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; } } }`  
  
  
  
在Win32ServiceManager中通过RemoteConnectValidate静态方法来测试连接成功与否；另外提供了GetServiceValue方法和GetServiceList方法以及它的重载来获取服务信息；后面的四个方法就是对服务的状态控制了。
