c# - The variable 'MyException' is declared but never used

Question

I need to clear this warning :

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

The complier is telling me :

The variable 'MyException' is declared but never used

How can I fix this.

1. You can remove it like this:

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

2. Use warning disable like this:

   try
   {
       doSomething()
   }
   #pragma warning disable 0168
   catch (AmbiguousMatchException exception)
   #pragma warning restore 0168
   {
       doSomethingElse()
   }
   

Other familiar warning disable

#pragma warning disable 0168 // variable declared but not used.
#pragma warning disable 0219 // variable assigned but not used.
#pragma warning disable 0414 // private field assigned but not used.
