应用程序停止响应

Question

我的Windows应用程序入口点是Main窗体构造函数。当应用程序启动时，它将启动一个线程，该线程保持运行状态。几天后，我的应用程序崩溃，提示应用程序弹出窗口停止工作。

public MDIForm()
{            
InitializeComponent();
AppDomain.CurrentDomain.UnhandledException += (s, e) =>
{
    Exception ex = (Exception)e.ExceptionObject;
    System.Diagnostics.Debug.WriteLine(ex.Message);
    logtofile"MDIForm; Error; UnhandledException;" + ex.Message);
    logtofile("MDIForm" + " StackTrace: UnhandledException: '{0}'" + Environment.StackTrace);
};
Application.ThreadException += (s, ex) =>
{
    Exception exc = (Exception)ex.Exception;
    System.Diagnostics.Debug.WriteLine(exc.Message);
    logtofile("MDIForm; Error; ThreadException; " + exc.Message);
    logtofile("MDIForm" + " StackTrace: ThreadException: '{0}'" + Environment.StackTrace);
};
}

以下功能在应用程序启动时从线程中调用。

private void MyFunction_RunThread()
{
try
{
    while (true)
    {
        //My Code
        Application.DoEvents();
        Thread.Sleep(200);
    }
}
catch (Exception Ex)
{
    //My Code
}
}

在添加了Stacetrace的代码之后，将捕获以下参考日志。
