C＃Windows应用程序阻止Windows关机/注销 [英] C# Windows application prevents Windows from shutting down / logging off

问题描述

我写了一个C＃Windows窗体应用程序，而不是服务（当用户登录并具有图形用户界面，它只是使用）具有无限循环运行的后台线程。

当我尝试关闭Windows（7），但是，它告诉我的计划是防止它关闭或注销，并询问我是否要强制关机。

现在，是否有可能对我的程序意识到（得到处理）的视窗试图戒烟，或注销？

所以，我需要的是让当Windows试图退出应用程序实现的。

在此先感谢。

编辑：感谢伟大的意见！它是在任何可能的方式使用了这个念头的形式关闭事件，如果它有一个取消的事件处理程序？

解决方案

 公共Form1中（）
 {
的InitializeComponent（）; 
 
 this.FormClosing + =新FormClosingEventHandler（Form1_FormClosing）; 
} 
 
无效Form1_FormClosing（对象发件人，FormClosingEventArgs E）
 {
 //或任何适合你要完成
什么其他的原因如果（e.CloseReason == CloseReason.WindowsShutDown）
 {
 //停止你的无限循环
} 
} 
  

I have written a C# Windows Forms application, not a service (it is only used when the user is logged in and has a graphical user interface) that has a background thread running in an infinite loop.

When I try shutting down Windows (7) however, it tells me the program is preventing it from shutting down or logging off and asks me whether I want to force a shutdown.

Now, is there any possibility for my program to become aware (get a handler) of Windows trying to quit it or to log off?

So, what I need is to make the application realize when Windows tries to quit.

Thanks in advance.

EDIT: Thanks for the great advice! Is it in any way possible to use the idea with the form closing event if it has a CANCEL event handler?

解决方案

public Form1()
{
    InitializeComponent();

    this.FormClosing += new FormClosingEventHandler(Form1_FormClosing);
}

void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    // Or any of the other reasons suitable for what you want to accomplish
    if (e.CloseReason == CloseReason.WindowsShutDown)
    {
        //Stop your infinite loop
    }
}
