The variable 'MyException' is declared but never used

Question

I need to clear this warning :

try
{
    doSomething()
}
catch (AmbiguousMatchException MyException)
{
    doSomethingElse()
}

The complier

Answer 1

but never used means that you should use it after catch() such as writing its value to console, then this warning message will disappear.

catch (AmbiguousMatchException MyException)
{
    Console.WriteLine(MyException); // use it here
}
