《c#远程控制服务》word版.doc

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.Wmipublic class Win32ServiceManager private string strPath;private ManagementClass managementClass;public Win32ServiceManager():this(.,null,null)public Win32ServiceManager(string host,string userName,string password)this.strPath = +host+rootcimv2:Win32_Service;this.managementClass = new ManagementClass(strPath);if(userName!=null&userName.Length0)ConnectionOptions connectionOptions = new ConnectionOptions();connectionOptions.Username = userName;connectionOptions.Password = password;ManagementScope managementScope = new ManagementScope( +host+ rootcimv2,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+ rootcimv2,connectionOptions) ;trymanagementScope.Connect();catchreturn 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 mopropertyName;/ 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()servicesi,0 = (string)moName;servicesi,1 = (string)moDisplayName;servicesi,2 = (string)moState;servicesi,3 = (string)moStartMode;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;iserverNames.Length;i+)mo.Path = new ManagementPath(this.strPath+.Name=+serverNamesi+);servicesi,0 = (string)moName;servicesi,1 = (string)moDisplayName;servicesi,2 = (string)moState;servicesi,3 = (string)moStartMode; 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+);tryif(string)moState=Stopped)/!(bool)moAcceptStopmo.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)moacceptPause&(string)moState=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)moacceptPause&(string)moState=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()
