Why use Console.SetIn(reader)?

Why use (option 1) Console.SetIn(reader) Console.WriteLine(Console.ReadLine()) instead of (option 2) Console.WrtieLine(reader.Reader.ReadLine())

What are the benefits to using option 1 over 2. 1 creates more lines and forces you to have to convert Console back to its standard input. By the how is that done? I tried OpenStandardInput but that still throws an error: System.ObjectDisposedException

It sounds like something being done of out order.

Your exception type makes it seem like you are trying to work with an object after it has been disposed. Perhaps your code needs to be moved into a using block?

You might need to show more of the code to make analysis possible.

I wasn't able to try it out, but what about this, starting at line 16:

            foreach (var line in fileLines) {
                using (var reader = new StreamReader(fileName))
                {
                  Console.SetIn(reader);
                  Console.WriteLine(Console.ReadLine());
                }
            }

If that's not it, please show the complete error message.
