Console.WriteLine("Enter a name");
string name ;
name = Console.ReadLine();

const string myname = "A";
const string sexyname = "B";
const string slliyname = "C";
const string forthname = "D";

switch (name.ToLower())

switch (name)
{
case "A":
Console.WriteLine("Right,this is your name");
break;
case "B":
Console.WriteLine("
