Question

I have an interesting task: to write a program which captures input from the program called Redmon. It is basically a virtual printer which redirects the output to a program.

I installed Redmon and created a winforms application to catch the output. But I’m stuck here. I checked what does my program receives and it is nothing on the parameter level (the string[] on main args are empty).

Redmon starts my program, but then it is stopping. I guess I should read somehow the content it is sending to the program, but how?

I would assume that Redmon streams to stdin – in which case you’ll have to read from the input stream – either via Console.In (if it is character-based), or Console.OpenStandardInput (for raw binary stream access).

As a trivial example of something that reads from stdin (it reads text lines, reversing each):

static void Main() {     WriteReversedLines(Console.In); } static void WriteReversedLines(TextReader reader) {     string line;     while ((line = reader.ReadLine()) != null) {         char[] chars = line.ToCharArray();         Array.Reverse(chars);         Console.WriteLine(chars);     } } 

Obviously you need to treat binary data slightly differently, but conceptually it is similar.
