1.使用WMI控制Windows进程
本文主要介绍两种WMI的进行操作：检查进程是否存在、创建新进行
代码如下：
using System; using System.Collections.Generic; using System.Text; using System.Management; using System.Threading; namespace TJVictor.WMI { public class Win32_Process:WMIBaseClass { #region Property private int timeout = 30; public int TimeOut { get { return timeout; } set { timeout = value; } } private string wqlSelect = "select * FROM Win32_Process where Name='{0}'"; #endregion #region Construction public Win32_Process() : base() { base.Connection(); } public Win32_Process(string domain, string Ip, string user, string psd) : base(domain, Ip, user, psd) { base.Connection(); } #endregion #region public function public bool IsProcessExist(string name) { if (!GetSelectQueryCollection(wqlSelect,name).Count.Equals(0)) return true; return false; } public void CreateProcess(string name) { ManagementClass processClass = new ManagementClass("Win32_Process"); processClass.Scope = base.Scope; ManagementBaseObject mbo = processClass.GetMethodParameters("Create"); mbo["CommandLine"] = string.Format(name); ManagementBaseObject result = processClass.InvokeMethod("Create", mbo, null); //检测执行结果 CheckExceptionClass.CheckProcessException(int.Parse(result["returnValue"].ToString())); //检测进程是否执行完成 int tempTimeout = this.timeout; while (!GetSelectQueryCollection("select * FROM Win32_Process where ProcessID='{0}'",result["ProcessID"].ToString()).Count.Equals(0)) { if (tempTimeout.Equals(0)) { throw new TJVictor.WMI.WmiException.ProcessException( string.Format("在 {0} 上执行 {1} 操作失败，执行超时", base.Ip, name)); } tempTimeout--; Thread.Sleep(1000); } } #endregion } }
2.使用WMI来控制Windows服务
本文介绍如何使用WMI来判断服务是否存在、如何创建新服务，删除服务、如何启服务、停服务
代码如下：
using System; using System.Collections.Generic; using System.Text; using System.Management; using System.Threading; namespace TJVictor.WMI { public class Win32_Service:WMIBaseClass { #region Property private bool completed = false; private int timeout = 30; public int TimeOut { get { return timeout; } set { timeout = value; } } private string wqlSelect = string.Empty; #endregion #region Construction public Win32_Service() : base() { wqlSelect = "select * FROM Win32_Service where Name='{0}'"; base.Connection(); } public Win32_Service(string domain, string Ip, string user, string psd) : base(domain, Ip, user, psd) { wqlSelect = "select * FROM Win32_Service where Name='{0}'"; base.Connection(); } #endregion #region public function public bool IsServiceExist(string name) { if (!GetSelectQueryCollection(wqlSelect,name).Count.Equals(0)) return true; return false; } public void StartService(string name) { if(!IsServiceExist(name)) throw new TJVictor.WMI.WmiException.ServiceException(string.Format("{0} 服务不存在",name)); object result = string.Empty; ManagementObjectSearcher mos = GetObjectSearcher(wqlSelect, name); foreach (ManagementObject mo in mos.Get()) { result = mo.InvokeMethod("StartService", null); break; } CheckExceptionClass.CheckServiceException(int.Parse(result.ToString())); TestServiceState(mos, "Running", string.Format("{0} 服务在 {1} 机器上启动失败，启动超时",name,base.Ip)); } public void StopService(string name) { if (!IsServiceExist(name)) throw new TJVictor.WMI.WmiException.ServiceException(string.Format("{0} 服务不存在", name)); object result = string.Empty; ManagementObjectSearcher mos = GetObjectSearcher(wqlSelect, name); foreach (ManagementObject mo in mos.Get()) { result = mo.InvokeMethod("StopService", null); break; } CheckExceptionClass.CheckServiceException(int.Parse(result.ToString())); TestServiceState(mos, "Stopped", string.Format("{0} 服务在 {1} 机器上停止失败，停止超时", name, base.Ip)); } public void CreateService(string name, string displayName, string startMode, string pathName, string startName, string startPassword, string serviceType) { if(IsServiceExist(name)) throw new TJVictor.WMI.WmiException.ServiceException(string.Format("{0} 服务已经存在",name)); int tempTimeout = this.timeout; ManagementClass processClass = new ManagementClass("Win32_Service"); processClass.Scope = base.Scope; string method = "Create"; ManagementBaseObject inputArgs = processClass.GetMethodParameters(method); inputArgs["Name"] = name; inputArgs["DisplayName"] = displayName; inputArgs["StartMode"] = startMode; inputArgs["PathName"] = pathName; if (!startName.Equals(string.Empty)) { inputArgs["StartName"] = startName; inputArgs["StartPassword"] = startPassword; } ManagementBaseObject ob = processClass.InvokeMethod(method, inputArgs, null); CheckExceptionClass.CheckServiceException(int.Parse(ob["returnValue"].ToString())); //检测服务是否已经安装成功 while (!IsServiceExist(name)) { if (tempTimeout.Equals(0)) { throw new TJVictor.WMI.WmiException.ServiceException( string.Format("在 {0} 上安装 {1} 服务超时", base.Ip, name)); } Thread.Sleep(1000); tempTimeout--; } } public void DeleteService(string name) { object result = string.Empty; if(!IsServiceExist(name)) throw new TJVictor.WMI.WmiException.ServiceException(string.Format("{0} 服务不存在",name)); foreach (ManagementObject mo in GetSelectQueryCollection(wqlSelect, name)) { result = mo.InvokeMethod("delete", null); break; } //检测卸载命令是否执行成功 CheckExceptionClass.CheckServiceException(int.Parse(result.ToString())); //检测服务是否已经卸载成功 int tempTimeout = this.timeout; while (IsServiceExist(name)) { if (tempTimeout.Equals(0)) { throw new TJVictor.WMI.WmiException.ServiceException( string.Format("在 {0} 上卸载 {1} 服务超时", base.Ip, name)); } Thread.Sleep(1000); tempTimeout--; } } #endregion #region private function private void TestServiceState(ManagementObjectSearcher mos, string state,string errorMes) { completed = false; int tempTimeout = timeout; while (!completed) { if (tempTimeout.Equals(0)) { throw new TJVictor.WMI.WmiException.ServiceException(errorMes); } foreach (ManagementObject mo in mos.Get()) { if (mo["State"].ToString().Equals(state)) { completed = true; } break; } Thread.Sleep(1000); tempTimeout--; } } #endregion } }
