C Sharp (C#) - Exception Handling

Consider this code snippet:

try {
  // code
} catch (Exception ex) when (ex is ArgumentException) {
  Console.WriteLine("Argument exception caught");
} catch (Exception ex) {
  Console.WriteLine("General exception caught");
}

BGeneral exception caught

CBoth messages printed

DArgument exception caught

Step-by-Step Solution

Solution:

Step 1: Understand exception filters with 'when'
The first catch block uses a filter to catch only ArgumentException instances.
Step 2: Exception matches filter and is caught by first block
The ArgumentException triggers the first catch block, printing "Argument exception caught".
