如何在.NET中以编程方式重新启动Windows服务？
此外，我需要在服务重启完成后执行操作。
答案 0 :(得分：69)
This article使用ServiceController类编写启动，停止和重新启动Windows服务的方法;可能值得一看。
文章中的片段（“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
{
// ...
}
}

查看ServiceController课程。
要执行重新启动服务时需要执行的操作，我想您应该自己在服务中执行此操作（如果它是您自己的服务）。
如果您无权访问该服务的来源，那么您可以使用WaitForStatus的{{1}}方法。

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);
}
}

您也可以调用net命令来执行此操作。例如：
System.Diagnostics.Process.Start("net", "stop IISAdmin");
System.Diagnostics.Process.Start("net", "start IISAdmin");

这个答案是基于@Donut答案（这个问题的最高投票答案），但有一些修改。
ServiceController类，因为它实现了IDisposable接口。serviceName参数，我们可以在构造函数中设置它，并且每个其他方法将使用该服务名称。 timeoutMilliseconds参数。StartOrRestart和StopServiceIfRunning，它们可以被视为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。这是班级
public class WindowsServiceController
{
private 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;
}
}
}
}

怎么样
var theController = new System.ServiceProcess.ServiceController("IISAdmin");
theController.Stop();
theController.Start();
不要忘记将System.ServiceProcess.dll添加到项目中以使其正常工作。

请参阅此article。
以下是article的摘录。
//[QUICK CODE] FOR THE IMPATIENT
using System;
using System.Collections.Generic;
using System.Text;

我需要更复杂的东西，因为有时依赖于服务的服务无法重新启动，只是抛出异常，或者服务可以设置为“禁用”，等等。
这就是我所做的：
（它检查服务是否确实存在，如果它的“ Disabled”将其设置为“ Auto”，当它无法重新启动服务时，它将使用taskkill命令通过PID终止服务，然后再次启动它（您需要谨慎使用相关服务，这也将导致您也需要启动/重新启动它们。
如果重新启动成功，它只会返回true / false
仅在WIN10上测试。
PS：正在使用可以在使用taskkill时检测相关服务并也将其重新启动的版本
//Get windows service status
public static string GetServiceStatus(string NameOfService)
{
ServiceController sc = new ServiceController(NameOfService);
switch (sc.Status)
{
case ServiceControllerStatus.Running:
return "Running";

return "Stopped";

return "Paused";

//finds if service exists in OS
public static bool DoesServiceExist(string serviceName)

ManagementObject objManage = new ManagementObject("Win32_Service.Name='"+serviceName+"'");
objManage.Get();
string status1 = objManage["StartMode"].ToString();
return status1;

您可以将服务设置为在失败后重新启动。因此，可以通过引发异常来强制重新启动。
使用服务属性上的恢复标签。
请务必使用重置失败计数属性，以防止服务完全停止。
答案 9 :(得分：-3)
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);
我在我的服务中做了同样的事情。它工作正常。
