error CS017: is informing you that the Class you are using does not contain the method you are trying to call. In this case, it does not contain methods 'Writeline', 'Readline or 'ToInt'.
But it does contain 'WriteLine' and 'ReadLine', remember C# uses Pascal case as part of the method naming convention.
And the ToInt method should be ToInt16, ToInt32, or ToInt64 depending on how large the number is.
