C# Switch Statement

C# does support Switch statement. if any case of the switch is met it will be executed.

C# Switch Rules:

  • The switch expression is evaluated once
  • The value of the expression is compared with the values of each case
  • If there is a match, the associated block of code is executed
  • The break and default keywords will be described later in this chapter

C# Switch Syntaxt

switch(expression) 
{
  case 1:
    // code block
    break;
  case 2:
    // code block
    break;
  default:
    // code block
    break;
}

C# Switch Example

using System;

namespace MyApplication
{
  class Program
  {
    static void Main(string[] args)
    {
      int day = 1;
      switch (day) 
      {
        case 1:
          Console.WriteLine("It's Monday");
          break;
        case 2:
          Console.WriteLine("It's Tuesday");
          break;
        case 3:
          Console.WriteLine("It's Wednesday");
          break;
        case 4:
          Console.WriteLine("It's Thursday");
          break;
        case 5:
          Console.WriteLine("It's Friday");
          break;
        case 6:
          Console.WriteLine("It's Saturday");
          break;
        case 7:
          Console.WriteLine("It's Sunday");
          break;
        default:
          Console.WriteLine("Not a valid week day number.");
          break;
      }    
    }
  }
}

Output
