Catch multiple Exceptions at once?

Pravesh Singh 2787 13 Jun 2013

It is discouraged to simply catch System.Exception, instead only the "known" Exceptions should be caught.

Now, this sometimes leads to unneccessary repetetive code, for example:

try
{
    WebId = new Guid(queryString["web"]);
}
catch (FormatException)
{
    WebId = Guid.Empty;
}
catch (OverflowException)
{
    WebId = Guid.Empty;
}

I wonder: Is there a way to catch both Exceptions and only call the WebId =

Guid.Empty call once?

Hello Pravesh Singh!

Catch System.Exception and switch on the types


catch (Exception ex)            

{                

    if (ex is FormatException || ex is OverflowException)

    {

        WebId = Guid.Empty;

        return;

    }

 

    throw;

}
