c programming help for my simple program

• A very basic understanding of the C programming language.
• Knowing how fgets works (with stdin).
• Knowing how printf works.

using System;
using System.Runtime.InteropServices;

namespace ConsoleApplication1
{
  class Program
  {
    static void Main(string[] args)
    {
      Console.WriteLine("Enter text to display:");
      var input = Console.ReadLine();
      Console.WriteLine(input);
      //Last read line is just to make the console stay open
      Console.ReadLine();
    }
  }
}
