为什么在Windows Service停止时调用base.OnStop()?

问题描述

我正在创建一个C#.Net Windows服务，想知道是否总是需要在该服务的 OnStop()方法中调用 base.OnStop(); 为什么?

I'm creating a C#.Net Windows Service and am wondering if you always have to call base.OnStop(); in the service's OnStop() method and why?

protected override void OnStop()
{
    threadRunning = false;

    this.ExitCode = 0;
    base.OnStop();
}

推荐答案

来自 ServiceBase.OnStop :

因此，它实际上用作停止服务的通知.

So it's really used as a notification to your service that it is stopping.

浏览一下ServiceBase.cs的.NET源代码，发现该方法无济于事:

A glance at the .NET source code for ServiceBase.cs reveals the method does nothing:

protected virtual void OnStop()
{
}

那么，您需要调用它吗?否.但是这样做仍然是一个很好的形式.基本实现可能有一天会更改.

So, do you need to call it? No. But it is still good form to do so. The base implementation may change someday.
