Question

in the XNA framework for example there is a SpriteBatch Class. The SpriteBatch.Begin() method accepts parameters like this:

spriteBatch.Begin(SpriteSortMode.FrontToBack, BlendState.AlphaBlend);

How can I create a class that accepts parameters in the same way?

Answer 1

create an Enum:

enum FooBarMode
{
     FrontToBack,
     BackToFront,
     Whatever
}

and use that as a parameter:

void DoSomething(FooBarMode mode)
{
    switch (mode) // just as an example
    {
        case FooBarMode.FrontToBack:
            Console.WriteLine("FrontToBack");
            break;
        case FooBarMode.BackToFront:
            Console.WriteLine("BackToFront");
            break;
        case FooBarMode.Whatever:
            Console.WriteLine("Whatever");
            break;
        default:
            throw new ArgumentOutOfRangeException("mode");
    }
}
