停止后台运行应用程序

你可以看看 this article on Detecting Form and Process Changes in CE .

我会听 Form.Deactivate event (或覆盖 Form.OnDeactivate Method 如果你拥有这门课)并检查 GetForegroundWindow 函数确定窗体是否在后台。如果不是,那么您就知道您的表单已发送到后台。

E.X.

using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Windows.Forms;
public class Form1 : Form
{
[DllImport("coredll")]
static extern IntPtr GetForegroundWindow();

[DllImport("coredll")]
static extern uint GetWindowThreadProcessId(IntPtr hWnd, out int lpdwProcessId);

protected override void OnDeactivate(EventArgs e)
{
    base.OnDeactivate(e);

    //if the foreground window was not created by this application, exit this application
    IntPtr foregroundWindow = GetForegroundWindow();
    int foregroundProcId;
    GetWindowThreadProcessId(foregroundWindow, out foregroundProcId);
    using (Process currentProc = Process.GetCurrentProcess())
    {
        if (foregroundProcId != currentProc.Id)
        {
            Debug.WriteLine("Exiting application.");
            Application.Exit();
        }
    }
}

}

我认为LostFocus事件可能是最可靠的解决方案。

如果是我,我会用反射来检查 发件人 LostFocus事件是我集会中的任何形式。如果没有,退出。
