Switch Statement in C#
The switch statement is similar to the if statement in that it executes code conditionally based on the value of a test. However, switch enables you to test for multiple values of a test variable in one go, rather than just a single condition. This test is limited to discrete values, rather than clauses such as “ greater than X, ” so its use is slightly different. But it can be a powerful technique.
Example
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
const string myName = "karli";
const string sexyName = "angelina";
const string sillyName = "ploppy";
string name;
Console.WriteLine("What is your name?");
name = Console.ReadLine();
switch (name.ToLower())
{
case myName:
Console.WriteLine("You have the same name as me!");
break;
case sexyName:
Console.WriteLine("My, what a sexy name you have!");
break;
case sillyName:
Console.WriteLine("That’s a very silly name.");
break;
}
Console.WriteLine("Hello {0}!", name);
Console.ReadKey();
}
}
}
