如何在.NET 中以编程方式重新启动 Windows 服务

看看 服务控制器类。

为了在服务重新启动时执行需要执行的操作，我想您应该自己在 Service 中执行该操作(如果它是您自己的服务)。
如果您不能访问服务的源，那么也许可以使用 ServiceController的 WaitForStatus方法。

本文 使用 ServiceController类编写用于启动、停止和重新启动 Windows 服务的方法; 值得一看。

文章的片段(“重新启动服务”方法) :

public static void RestartService(string serviceName, int timeoutMilliseconds)
{
ServiceController service = new ServiceController(serviceName);
try
{
int millisec1 = Environment.TickCount;
TimeSpan timeout = TimeSpan.FromMilliseconds(timeoutMilliseconds);


service.Stop();
service.WaitForStatus(ServiceControllerStatus.Stopped, timeout);


// count the rest of the timeout
int millisec2 = Environment.TickCount;
timeout = TimeSpan.FromMilliseconds(timeoutMilliseconds - (millisec2-millisec1));


service.Start();
service.WaitForStatus(ServiceControllerStatus.Running, timeout);
}
catch
{
// ...
}
}

看这个 文章。

下面是来自 文章的一个片段。

//[QUICK CODE] FOR THE IMPATIENT
using System;
using System.Collections.Generic;
using System.Text;
// ADD "using System.ServiceProcess;" after you add the
// Reference to the System.ServiceProcess in the solution Explorer
using System.ServiceProcess;
namespace Using_ServiceController{
class Program{
static void Main(string[] args){
ServiceController myService = new ServiceController();
myService.ServiceName = "ImapiService";
string svcStatus = myService.Status.ToString();
if (svcStatus == "Running"){
myService.Stop();
}else if(svcStatus == "Stopped"){
myService.Start();
}else{
myService.Stop();
}
}
}
}

怎么样

var theController = new System.ServiceProcess.ServiceController("IISAdmin");


theController.Stop();
theController.Start();

不要忘记将 System.ServiceProcess.dll 添加到您的项目中以使其工作。

您也可以调用 net命令来完成这项工作。例如:

System.Diagnostics.Process.Start("net", "stop IISAdmin");
System.Diagnostics.Process.Start("net", "start IISAdmin");

ServiceController 类使用的示例

private void RestartWindowsService(string serviceName)
{
ServiceController serviceController = new ServiceController(serviceName);
try
{
if ((serviceController.Status.Equals(ServiceControllerStatus.Running)) || (serviceController.Status.Equals(ServiceControllerStatus.StartPending)))
{
serviceController.Stop();
}
serviceController.WaitForStatus(ServiceControllerStatus.Stopped);
serviceController.Start();
serviceController.WaitForStatus(ServiceControllerStatus.Running);
}
catch
{
ShowMsg(AppTexts.Information, AppTexts.SystematicError, MessageBox.Icon.WARNING);
}
}

使用大于0的错误代码调用 Environment.Exit，这似乎是合适的，然后在安装时，我们将服务配置为在出错时重新启动。

Environment.Exit(1);

我在我的服务中也做过同样的事情，它运行得很好。

这个答案是基于@Donut 的答案(这个问题最受欢迎的答案) ，但是有一些修改。

1. 在每次使用后处理 ServiceController类，因为它实现 IDisposable接口。
2. 减少方法的参数: 不需要为每个方法传递 serviceName参数，我们可以在构造函数中设置它，每个方法都将使用该服务名。
   这也更加面向对象友好。
3. 处理 catch 异常的方式使这个类可以用作组件。
4. 从每个方法中删除 timeoutMilliseconds参数。
5. 添加两个新的方法 StartOrRestart和 StopServiceIfRunning，它们可以被认为是其他基本方法的包装器，这些方法的目的只是为了避免异常，如注释中所述。

这是全班同学

public class WindowsServiceController
{
private readonly string serviceName;


public WindowsServiceController(string serviceName)
{
this.serviceName = serviceName;
}


// this method will throw an exception if the service is NOT in Running status.
public void RestartService()
{
using (ServiceController service = new ServiceController(serviceName))
{
try
{
service.Stop();
service.WaitForStatus(ServiceControllerStatus.Stopped);


service.Start();
service.WaitForStatus(ServiceControllerStatus.Running);
}
catch (Exception ex)
{
throw new Exception($"Can not restart the Windows Service {serviceName}", ex);
}
}
}


// this method will throw an exception if the service is NOT in Running status.
public void StopService()
{
using (ServiceController service = new ServiceController(serviceName))
{
try
{
service.Stop();
service.WaitForStatus(ServiceControllerStatus.Stopped);
}
catch (Exception ex)
{
throw new Exception($"Can not Stop the Windows Service [{serviceName}]", ex);
}
}
}


// this method will throw an exception if the service is NOT in Stopped status.
public void StartService()
{
using (ServiceController service = new ServiceController(serviceName))
{
try
{
service.Start();
service.WaitForStatus(ServiceControllerStatus.Running);
}
catch (Exception ex)
{
throw new Exception($"Can not Start the Windows Service [{serviceName}]", ex);
}
}
}


// if service running then restart the service if the service is stopped then start it.
// this method will not throw an exception.
public void StartOrRestart()
{
if (IsRunningStatus)
RestartService();
else if (IsStoppedStatus)
StartService();
}


// stop the service if it is running. if it is already stopped then do nothing.
// this method will not throw an exception if the service is in Stopped status.
public void StopServiceIfRunning()
{
using (ServiceController service = new ServiceController(serviceName))
{
try
{
if (!IsRunningStatus)
return;


service.Stop();
service.WaitForStatus(ServiceControllerStatus.Stopped);
}
catch (Exception ex)
{
throw new Exception($"Can not Stop the Windows Service [{serviceName}]", ex);
}
}
}


public bool IsRunningStatus => Status == ServiceControllerStatus.Running;


public bool IsStoppedStatus => Status == ServiceControllerStatus.Stopped;


public ServiceControllerStatus Status
{
get
{
using (ServiceController service = new ServiceController(serviceName))
{
return service.Status;
}
}
}
}

如果你使用.NET 核心，你必须下载 System.ServiceProcess 包
这只能在 WINDOWS 上使用
