Console end of input

Question

Consider the following loop:

While Console.In.Peek() >= 0
    Console.WriteLine(Console.ReadLine())
End While

It works as expected (i.e. echos the input) when the input is re-directed from a file. However, when the lines are typed in console, the program exits after the first line. Why does this happen and how can it be fixed? In other words, what should I write in the loop condition so that it exits only when Ctrl+Z is typed?

Answer 1

    While (Console.ReadLine IsNot Nothing)
        Console.WriteLine(Console.ReadLine())
    End While

You have to hit enter after Ctrl+Z for this to work. Ctrl+Z returns null
