How do you create a method in C# that takes a multiple set amount of values?

Question

I'm wondering how in C# I would go about creating a method that would take a couple set values, kind of like an enum.

public static void SwitchState(enum State { On, Off, Idle }) {

}

Something like that I don't know...I don't want to have strings passed into the method because then I have to memorize what those strings are.

When using one of the answers below, it's always good to add the [Flags] attribute to your enum (when allowing multiples)- see answer here for info http://stackoverflow.com/questions/8447/what-does-the-flags-enum-attribute-mean-in-c — Darren Wainwright, Dec 09 '16 at 21:08

You actually can use enums like this

public enum SpotifyAction
{
            PlayPause,
            Next,
            Previous,
            VolumeUp,
            VolumeDown,
            Mute,
            Quit
};

public static void controlSpotify(SpotifyAction sa)
{
            BringToForeground("Spotify");

            switch (sa)
            {
                case SpotifyAction.Next:
                    SendKeys.SendWait("^({RIGHT})");
                    break;
                case SpotifyAction.Previous:
                    SendKeys.SendWait("^({LEFT})");
                    break;
                case SpotifyAction.VolumeUp:
                    SendKeys.SendWait("^({UP})");
                    break;
                case SpotifyAction.VolumeDown:
                    SendKeys.SendWait("^({DOWN})");
                    break;
                case SpotifyAction.PlayPause:
                    SendKeys.SendWait(" ");
                    break;
            }
}

You just create an enum and then pass it to the method.

public enum State
{
        On, 
        Off,
        Idle
}

private void SwitchState(State stateValue)
{

}

private void testCall()
{
    SwitchState(State.Idle);
}

void Main()
{
    SwitchState(State.On | State.Off);
}

public void SwitchState(State s)
{
    //...
}

public enum State
{
    None = 0,
    On = 1,
    Off = 2,
    Idle = 4
}
