Assert.Catch

Assert.Catch is similar to Assert.Throws but will pass for an exception that is derived from the one specified.

Exception Assert.Catch( TestDelegate code );
Exception Assert.Catch( TestDelegate code, 
                        string message, params object[] parms);

Exception Assert.Catch( Type expectedExceptionType, TestDelegate code );
Exception Assert.Catch( Type expectedExceptionType, TestDelegate code, 
                        string message, params object[] parms);

T Assert.Catch<T>( TestDelegate code );
T Assert.Catch<T>( TestDelegate code, 
                 string message, params object[] parms);
