Console.ReadLine(); ??????

Reads the next line of characters from the standard input stream.

One of the most common uses of the ReadLine method is to pause program 

execution before clearing the console and displaying new information to 

it, or to prompt the user to press the Enter key before terminating the

application.

Console.WriteLine("Enter your name: "); 

name = Console.ReadLine();

// "Console.ReadLine()" is used to get user input

//for example

Console.WriteLine("What is your name?");

  string Name = Console.ReadLine();

    Console.WriteLine("Hello " + Name);

// C# program to illustrate

// the use of Console.ReadLine()

// to pause the console

using System;

using System.IO;

class Geeks {

    // Main Method

    public static void Main()

    {

        string name;

        int n;

        Console.WriteLine("Enter your name: ");

        // typecasting not needed as

        // ReadLine returns string

        name = Console.ReadLine();

        Console.WriteLine("Hello " + name +

             " Welcome to GeeksforGeeks!");

        // Pauses the console until

        // the user presses enter key

        Console.ReadLine();

    }
