Switch Statements

Why use a Switch Statement?

Switch statements to exactly the same thing as If Statements. However, they look neater if you are checking for lots of values. For example the following code will check the month number and print out the month name:

switch (MonthNumber) 
{
    case 1:
        Console.WriteLine("January");
        break;
    case 2:
        Console.WriteLine("February");
        break;
    case 3:
        Console.WriteLine("March");
        break;
    case 4:
        Console.WriteLine("April");
        break;
    case 5:
        Console.WriteLine("May");
        break;
    case 6:
        Console.WriteLine("June");
        break;
    case 7:
        Console.WriteLine("July");
        break;
    case 8:
        Console.WriteLine("August");
        break;
    case 9:
        Console.WriteLine("September");
        break;
    case 10:
        Console.WriteLine("October");
        break;
    case 11:
        Console.WriteLine("November");
        break;
    case 12:
        Console.WriteLine("December");
        break;
    default:
        Console.WriteLine("Error. Please choose a number between 1 an 12");
        break;
}

Use default to catch any other value. This is like else in an if statement.
