Question

我有一个Winforms应用程序，它有一个Winform控件并启动一个线程。为了捕获Winform控件引发的异常，我实现了ThreadExceptionHandler。当控件中发生异常时，我想做两件事：记录它并停止线程以便应用程序停止。问题是我无法访问记录器和ThreadExceptionhandler中的线程，因为它是静态的。因此，我无法执行日志记录，更糟糕的是，结束线程。

 static void Main()
    {
        MainForm form = null;
        try
        {

            Application.ThreadException += new ThreadExceptionEventHandler(MainForm.ThreadExceptionHandler);

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            form = new MainForm();
            Application.Run(form);
        }
        catch (Exception ex)
        {
            form.logger.log(ex);
            form.thread.Stop();
        }
    }

和MainForm类：

 public partial class MainForm : Form
 {
    internal MyThread thread;
    internal Logger logger = new Logger();
    public MainForm()
    {
        MyForm formThatThrowsAnException = new MyForm();
        thread = new MyThread();
        thread.Isbackground = false; // prevents app from stopping
    }

    internal static void ThreadExceptionHandler(object sender, ThreadExceptionEventArgs args)
    {
        try
        {
            // log here
            // stop thread here
        }
        catch { }
    }
}

}

我试着这样做：

        MainForm form = null;
        try
        {
            form = new MainForm();
            Application.ThreadException += new ThreadExceptionEventHandler(form.ThreadExceptionHandler);
           ...

并从异常处理程序方法中删除static关键字，但这不起作用，因为没有调用该方法。

<强> MyThread的

internal static void Stop(){...}

<强>日志

internal static void log(){...}

主要形式：

internal MyThread thread;
internal Logger logger = new Logger();

public MainForm()
{
    MyForm formThatThrowsAnException = new MyForm();
    thread = new MyThread();
    thread.Isbackground = false; // prevents app from stopping

}

internal static void ThreadExceptionHandler
              (object sender, ThreadExceptionEventArgs args){
    try
    {
          Logger.log(new Exception());
          MyThread.Stop();
    }
    catch { }
}

主要功能：

static void Main()
{
    MainForm form = null;
    try
    {
        Application.ThreadException += MainForm.ThreadExceptionHandler;
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        form = new MainForm();
        Application.Run(form);
    }
    catch (Exception ex)
    {
        if (form != null)
        {
            Logger.log(ex);
            MyThread.Stop();
        }
    }
}

在UnhandledExceptionHandler中停止线程
