That is sending the file to standard input, so you can get the data stream through the Console.In property.

Here's a quick proof of concept:

public static void Main(string[] args)
{
    var fileContents = System.Console.In.ReadToEnd();
    System.Console.Write(fileContents);
}

This was called on the command prompt with:

program.exe < file.txt

As pointed out by P0W, that is a function of cmd.exe, not C#. However, in C#, you would use the various Console.ReadXXX methods to get data from standard input.

Input/Output re-direction works for all executable independent of language.

So just read the file in normal way from standard input
