try- catch. Handling multiple exceptions the same way (or with a fall through)

Question

There has already been a question posted here which is very similar. Mine is extending that question a bit more. Say you want to catch multiple types of exception but want to handle it the same way, is there a way to do something like switch case ?

switch (case)
{
  case 1:
  case 2:

  DoSomething();
  break;
  case 3:
  DoSomethingElse()
  break;

}

Is it possible to handle few exceptions the same way . Something like

try
{
}
catch (CustomException ce)
catch (AnotherCustomException ce)
{
  //basically do the same thing for these 2 kinds of exception
  LogException();
}
catch (SomeOtherException ex)
{
 //Do Something else
}

Answer 1

Currently there is no language construct to accomplish what you want. Unless the exception all derive from a base exception you need to consider refactoring the common logic to a method and call it from the different exception handlers.

Alternatively you could do as explained in this question:

Catch multiple Exceptions at once?

Personally I tend to prefer the method-based approach.

Answer 2

You should really have a BaseCustomException and catch that.

Answer 3

This is copied from another posting, but I am pulling the code to this thread:

Catch System.Exception and switch on the types

catch (Exception ex)            
{                
    if (ex is FormatException || ex is OverflowException)
    {
        WebId = Guid.Empty;
        return;
    }

    throw;
}

I prefer this to repeating a method call in several catch blocks.
