Question

I have a command line application called “MyApp.exe”, that I want to use like this:

DoSomething|MyApp.exe

That is, DoSomething outputs a string to standard out, and then the pipe sends it as standard in to MyApp.exe.

How can I accept this string in MyApp.exe?

UPD.

And what if I want to test this?
I’m using public methods to start my application activity:

using (MyApp app = new MyApp())
{ 
 result = app.Run(args);
}
If(result!=0) Assert.Fail("Failed");

I.e. I need to write some data into input stream before execute Run()

You can use Console.In to access stdin.

Or Console.ReadLine() which is just a shortcut for Console.In.ReadLine().
