[Source] .NET/C# threads catch exception information

[Copy link]
Posted on 9/23/2020 7:59:52 PM | | | |
Recently, I had an interview with a question about how to get thread exceptions, and I answered incorrectly. I also get exceptions by writing try catch outside the thread I said.

In the past, when I was doing winform software development, I often used threads, and there were two ways for me to obtain exception information:

  • Write try catch in the thread, and call the delegate to output the exception information to the software log text box.
  • Write a try catch in the thread, call the log framework, and write to the file.


I also didn't write try catch outside the thread, so why did I answer incorrectly?

Test code:



No exception information was obtained outside the thread, and the main thread died, no "OK" printed.

What should I do if I want to get the exception information of the thread in the main thread? You can use events, which are actually delegates.

Tutorial on the event:

.net/c# event for details

The code is as follows:

Exceptions using Task are not handled and do not affect the main thread



If the Thread exception is not handled, the main thread crashes
