Question

我的逻辑层中有一个函数，它通过另一个线程插入信息，我希望如果在该线程中发生未知异常抛出它，但问题是在我的应用程序UnhandledExceptionEventHandler中获得一般异常会产生此错误我也不想关闭应用程序：

调用线程必须是STA，因为许多UI组件需要此

///////////////////// this is my function in logical layer //////////
public string MahaleInsert(Mahales Mahale)
{
    Thread t = new Thread(delegate()
    {
        try
        {
            Mahale.OutMessage = DA_Agency.MahaleInsertDB(Mahale);
            Mahale.OutMessage = "SuccessInsert";
        }
        catch (Exception ex)
        {
            if (ex.Message.ToLower().Contains("violation of unique key constraint"))
                Mahale.OutMessage = "MahaleInsUniqueError";
            else
                throw;
        }
    });
    t.Start();
    t.Join();
    return Mahale.OutMessage;    
}

//////////////////////////// this in my aplication level  //////////////////
void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
    try
    {
        string messsage = GeneralMethod.CatchException(e.ExceptionObject as Exception);
        MessageClass.MessageBox(messsage);
    }
    catch
    {


    }
}

尝试执行以下操作：

    public string MahaleInsert(Mahales Mahale)
    {
        Thread t = new Thread(new ThreadStart(ThreadBody));
        t.Start();
        t.Join();
        return Mahale.OutMessage;
    }
    [STAThread]
    void ThreadBody()
    {
        try
        {
            Mahale.OutMessage = DA_Agency.MahaleInsertDB(Mahale);
            Mahale.OutMessage = "SuccessInsert";
        }
        catch (Exception ex)
        {
            if (ex.Message.ToLower().Contains("violation of unique key constraint"))
                Mahale.OutMessage = "MahaleInsUniqueError";
            else
                throw;
        }
    }

    //////////////////////////// this in my aplication level  //////////////////
    void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
    {
        try
        {
            string messsage = GeneralMethod.CatchException(e.ExceptionObject as Exception);
            MessageClass.MessageBox(messsage);
        }
        catch
        {


        }
    }
