Question

I guess there is no difference between these three parts of code, is not it?

   try
    {
       // .............
    }
    catch
    {
        // ............. 
    }

and

   try
    {
       // .............
    }
    catch(Exception)
    {
       // .............  
    }

and

try
{
   // .............
}
catch(Exception e)
{
    // ............. 
}

However I am almost savvy when should be used the first one and when – the second. But I would like you to tell your ideas.

Answer 1

The first one will also catch thrown objects that aren’t exceptions.
(this can happen from non-CLS-compliant code)

The second one will not give a compiler warning if you don’t actually use the exception variable.

The third one should be used only if you actually need to inspect the thrown exception (eg, to log it).
