Case "01" To "04" :

Hi,
If you r looking for switch case in c#:

string myInput;
        int myInt;

        begin:

        Console.Write("Please enter a number between 1 and 3: ");
        myInput = Console.ReadLine();
        myInt = Int32.Parse(myInput);

        // switch with integer type
        switch (myInt)
        {
            case 1:
                Console.WriteLine("Your number is {0}.", myInt);
                break;
            case 2:
                Console.WriteLine("Your number is {0}.", myInt);
                break;
            case 3:
                Console.WriteLine("Your number is {0}.", myInt);
                break;
            default:
                Console.WriteLine("Your number {0} is not between 1 and 3.", myInt);
                break;

I don't think c# has such a thing as "To" like Visual Basic. But it can be done like this:

switch (var)
{
        case "01":
        case "02":
        case "03":
        case "04":
                DoStuff();
                break;
        default:
                break;
}
