如何在LAN断开连接并重新连接时使用C＃重新启动服务 [英] How to restart a service using C# when lan is disconnected and connected back

问题描述

您好我正在尝试执行一个c＃程序，该程序应该在拔下lan电缆并重新插入系统时重新启动服务。请帮帮我。



我的尝试：



我有尝试重新启动服务一段时间，但我需要它，当一个局域网被拔掉并插入后面。

Hi i am trying to execute a c# program which should restart a service when a lan cable is unplugged and plugged back to system. Please help me.

What I have tried:

I have tried restarting the service for a certain time period, but i need it when a lan is unplugged and plugged in back.

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);
  }

推荐答案

你可以监控NetworkChange.NetworkAvailabilityChanged Event（System.Net.NetworkInformation） [ ^ ]以便对更改作出反应。



但是，我必须说，单独的程序以这种方式重启服务听起来很奇怪。在大多数情况下，我认为服务应该自动处理这种情况。

You could monitor NetworkChange.NetworkAvailabilityChanged Event (System.Net.NetworkInformation)[^] in order to react upon changes.

However, I must say that it sounds odd that a separate program restarts the service this way. In most situations I believe that the service should autonomously handle the situation.
