C# ReadKey crashing console app when called using <nul

Question

So I decided to start programming in C#, and one of the things I did was to create a "pausec.exe" (a pause.exe clone). It works, but when calling it like:

< nul pausec  

...it crashes. The error I get - translated from Spanish to the best of my knowledge - goes like this:

Unhandled exception: System.InvalidOperationException: Can't read keys when any of the applications doesn't have a console or when the console input has been redirected from a file. Try with Console.Read.

And the stacktrace telling me where the error is:

 in System.Console.ReadKey(Boolean intercept)  
 in System.Console.ReadKey()  
 in pausec.Program.Main(String[] args)

This is the code I'm running:

using System;

namespace pausec
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.Write("Press any key to continue . . . ");
            Console.ReadKey(true);
            Console.Write("\n");
        }
    }
}

I'm wondering if there's a workaround for this, maybe even a way to ignore the ReadKey when using < nul?

Any help is appreciated.
Thanks in advance

UPDATE: Found a way, by removing the intercept (as Alberto Solano suggested) and then, adding Console.Write("\b \b"); after the ReadKey method, it works. Weird thing is, when I copy the application to my desktop, it doesn't wait for user input and closes automatically.

UPDATE 2: It works perfectly now. Thank you all for answering!

The console has a method that you can check to see if stdin has been redirected.

public static bool IsInputRedirected { get; }
