How can I "use" a variable to stop an error message saying it's not used?

Question

My IDE is always opening up and giving me this message:

try
{
   await Task.Delay(1000, App.tokenSource2.Token);
}
catch (TaskCanceledException ex) { ex = null; }

The variable ex is declared but never used.

I would like to avoid being the message. Any suggestions?

You can disable the pragma warning - https://stackoverflow.com/questions/3820985/suppressing-is-never-used-and-is-never-assigned-to-warnings-in-c-sharp — ArcX, Aug 29 '17 at 06:51

Just dont specify any variable if you are not planning to use it:

try
{
   await Task.Delay(1000, App.tokenSource2.Token);
}
catch (TaskCanceledException) { ... }

he might want it to breakpoint and look into it in the debugger – Haukinger Aug 29 '17 at 06:46

In the debugger you can always check exception via locals window or just add $exception in watch list. – 3615 Aug 29 '17 at 06:47
