System.Console has no Contents method.

But it looks like you had part of the right idea from the commented-out lines. One you select your streamreader using SetIn, you can then use ReadLine to get a line from it:

            Console.SetIn(reader); 
            Console.WriteLine(Console.ReadLine());
