Asp.net中的线程异常处理 [英] Exception handling with threads in Asp.net

问题描述

我的代码在线程内部有一个线程.我使用了 try catch block ，所以当发生异常时，它将在标签中显示，例如...

My code has a thread inside thread. I used try catch block, so when an exception occurs, it will be shown in label like...

ThreadStart threadstartprint = () => CreatePDF();
Thread threadprint = new Thread(threadstartprint);

CreatePDF()
{
     try
     {
     }
     catch(Exception ex)
     {
          lbl.text=ex.message;
     }
}

我的问题是，即使发生异常，也不会显示.
有什么方法可以捕获线程中的异常并显示该异常吗?

My problem is that even if an exception is occurred, but it is not showed.
Is there any way to catch exception in thread and show that exception ?

推荐答案

您尚未启动线程，因此控件未调用我正在获取的CreatePDF()方法根据您指定的代码.

您更新的代码应如下所示:-尝试使用此代码可能会有所帮助...

You have not started your thread so control is not invoking CreatePDF() method Which i am getting by your given code.

Your updated code should be like below :- Try this one may help...

ThreadStart threadstartprint = () => CreatePDF();
Thread threadprint = new Thread(threadstartprint);
threadprint.Start();

CreatePDF()
{
     try
     {
     }
     catch(Exception ex)
     {
          lbl.text=ex.message;
     }
}
