Description Jonathan Chambers 2016-10-13 16:37:50 UTC

"If an exception is thrown inside the filter block, it is intercepted and a value of 0 (exception_continue_search) is returned."

.Net Output
Finally block after filter
Caught exception not handled by filter

Mono Output
Finally block after filter
Caught exception thrown in filter

// Test  case
using System;

class Program
	class FilterException : Exception { }
	class ThrowInFilterException : Exception { }

	static void Main (string[] args)
			RaiseExceptionWithFilter (() =>
				throw new ThrowInFilterException ();
		catch (ThrowInFilterException)
			Console.WriteLine ("Caught exception thrown in filter");
		catch (FilterException)
			Console.WriteLine ("Caught exception not handled by filter");

	public static void RaiseExceptionWithFilter (Func<bool> filterFunc)
			throw new FilterException ();
		catch (FilterException ex) when (filterFunc ())
			Console.WriteLine ("Caught exception in filter " + ex);
			Console.WriteLine ("Finally block after filter");

		Console.WriteLine ("Code after filter");
