I got answer of my question on internet which is as follow:
Because Key is used to determine which key has pressed.

If you press for example the A key you will get 'A' in output but there are two 2 keys on a standard keyboard. One is on top of keyboard and other one is on number pad.

Key represents Key Enum, by this you are able to determine which 2 key has pressed.

If you press 2 on top of keyboard you will get D2 in output.

If you press 2 on number pad you will get NumPad2 in output.

If you need exact '2' on output use KeyChar instead of key.
static void Main(string[] args)

{

    ConsoleKeyInfo m = Console.ReadKey();

    Console.WriteLine("\r\n Console key is:" + m.Key);

    Console.WriteLine("\r\n Unicode character is:" + m.KeyChar);

    Console.ReadKey();

}

m.Key returns the console key. To print character value use m.KeyChar like below

Console.WriteLine("\n" + m.KeyChar);
