c# Start/Stop/Check Status远程计算机的Windows Service
 static void Main(string[] args)
{
ConnectionOptions op = new ConnectionOptions();
// 登陆远程计算机的远程,
op.Username = "Domain\\Domainuser";
op.Password = "password";
// 该处不能使用ip必须是"计算机名称.域名\root\cimv2"
ManagementScope scope = new ManagementScope(@"\\Servername.Domain\root\cimv2", op);
scope.Connect();
ManagementPath path = new ManagementPath("Win32_Service");
using(ManagementClass services = new ManagementClass(scope, path, null))

Console.WriteLine("{0}:{1}",service.GetPropertyValue("Name").ToString(),service.GetPropertyValue("State").ToString());

如何远程Stop/Start远程机子上的服务?

在gfsoso上搜出别人总结的经验: http://www.gkspk.com/view/programming/working-with-windows-services-using-csharp-and-wmi/

远程控制可以有以下几种方式:

  • WMI Queries via classes in the System.Management namespace,
  • Strongly-typed WMI proxy classes generated using MgmtClassGen.exe, and
  • The System.ServiceProcess.ServiceController class.

WMI queries

首先我们需要使用ConnectionOptions来连通远程机:

 ConnectionOptions options = new ConnectionOptions();

 // If we are connecting to a remote host and want to
// connect as a different user, we need to set some options
//options.Username =
//options.Password =
//options.Authority =
//options.EnablePrivileges = // If we are connecting to a remote host, we need to specify the hostname:
//string providerPath = @"\\Hostname\root\CIMv2";
string providerPath = @"root\CIMv2"; ManagementScope scope = new ManagementScope(providerPath, options);
scope.Connect();

我们使用WMI支持一种查询方式叫做WQL,它的用法是类似于SQL。我们可以使用WQL去查询某台服务器的上的服务运行状态:

ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_Service WHERE Name LIKE 'SQL%'");
ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query); foreach (ManagementObject o in searcher.Get())
{
string name = o["Name"];
...
}

我们可以使用ManagementObject去对单个远程的WindowsService进行控制:比如停止服务(Invoke函数:StopService)或者启动服务(Invoke 函数:StartService);

 ManagementPath path = new ManagementPath("Win32_Service.Name='SomeWindowsService'");
ManagementObject obj = new ManagementObject(scope, path, new ObjectGetOptions());
ManagementBaseObject outParams = obj.InvokeMethod("StartService", (ManagementBaseObject)null, null);
uint returnCode = System.Convert.ToUInt32(outParams.Properties["ReturnValue"].Value);

上边这种方法是一种同步的方法,当然我们也可以使用异步接收InvokeMethod执行结果。

 ManagementOperationObserver observer = new ManagementOperationObserver();
// The ObjectReadyHandler method will need a prototype of
// public void ObjectReadyHandler(object sender, ObjectReadyEventArgs e) { ... }
observer.ObjectReady += ObjectReadyHandler;
obj.InvokeMethod(observer, "StartService", new object[]);

ManagementOperationObserver有两个事件可以订约,你可以订约ObjectReady,也可以订约Completed事件。

WMI proxy classes

你可以使用.NET Framework包含的一个强类型WMI代理类生成工具,你可以是使用一下命令生成对类Win32_Service的代理类:

MgmtClassGen.exe Win32_Service /L CS /O some.namespace /N root\cimv2 /P ServiceProxy.cs

执行这些代码后,你将得到一个ServiceProxy.cs文件,在使用该代理类的时候,你还需要结合ConnectionOptions使用:

 string condition = "Name LIKE 'SQL%'";
ServiceProxy.ServiceCollection sc = ServiceProxy.GetInstances(scope, condition);
foreach (ServiceProxy s in sc)
{
string name = s.Name;
...
s.StartService();
}

Service Controller

System.Management.dll下微软封装好了一个这样的类,该类也是我们大多数人对本地服务进行操作时,搜选方案,当时远程机也可以,但该类在操作远程机时,必须要启动你的软件以有权限操作其他机子的账户(比如:账户A在你的远程机上也有该账户,在远程机上该账户也有对WMI操作权限)。

所以说,当在控制远程机上的服务时,使用该类的局限性很大,而且不可以切换用户。

 ServiceController controller = new ServiceController("servicename", "hostname");
if (ServiceControllerStatus.Stopped == controller.Status)
{
controller.Start();
// You can use the following line to wait for service to finish starting
// you can supply a TimeSpan object to this method to timeout after that period.
controller.WaitForStatus(ServiceControllerStatus.Running);
}

运行结果,果然不负众望。
