When I try to compile the code I get a slew of errors such as the ones below

Error	1	'int' does not contain a definition for 'InList'
Error	2	'string' does not contain a definition for 'InList'	
Error	3	'System.Array' does not contain a definition for 'Contains'	

have you compiled it ? ( I'm using VS2005 but have access to VS2008 )
