Creating CLR table function with T-SQL producing error msg 6208.

I created an assembly using T-SQL. I then tried to create the function using T-SQL but I get the error:"CREATE FUNCTION failed because the parameter count for the FillRow method should be one more than the SQL declaration for the table valued CLR function."I couldn't find anything helpful on the web.C# code and T-SQL statement attached.Any help would be greatly appreciated.Thanks!
