如何从线程中获取异常消息...? [英] how to get an exception message from thread...???

问题描述

在我的线程中运行的方法给出了异常.我想将该异常消息发送到主线程.
请告诉我该怎么做.
这是我的代码部分

公共无效导入(字符串ID)
{
试试
{
线程t1 =新线程(ImportThread1);
线程t2 =新线程(ImportThread2);
t1.Start(obj1);
t2.Start(obj2);
t1.Join();
t2.Join();
}
catch(ex ex例外)
{
Console.WriteLine(ex.Message);
}
}

私有void ImportThread1(对象信息)
{
试试
{
Method1(info.ToString);
}
catch(ex ex例外)
{
扔前//我想将此异常传递给主线程
}
}

私有void ImportThread1(对象信息)
{
试试
{
Method2(info.ToString);
}
catch(ex ex例外)
{
扔前//我想将此异常传递给主线程
}
}

the method which runs in my thread gives an exception. i want to get that exception message to the main thread.
please tell me how to do this.
here is my code part

public void Import(string id)
{
try
{
Thread t1 = new Thread(ImportThread1);
Thread t2 = new Thread(ImportThread2);
t1.Start(obj1);
t2.Start(obj2);
t1.Join();
t2.Join();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}

private void ImportThread1(object info)
{
try
{
Method1(info.ToString);
}
catch (Exception ex)
{
throw ex; // i want to pass this exception to the main thread
}
}

private void ImportThread1(object info)
{
try
{
Method2(info.ToString);
}
catch (Exception ex)
{
throw ex; // i want to pass this exception to the main thread
}
}

推荐答案

有很多解决方案可以做到这一点.

您可以使用AppDomain.CurrentDomain.UnhandledException来执行此操作.看看这个:

There are lots of solutions to do this.

You might use AppDomain.CurrentDomain.UnhandledException to do this. Take a look into this :

Other than that, you can also create a callback to send exception as data after handling it properly inside the child thread and ReThrow the exception in the main thread from the callback.
