C# How to use get, set and use enums in a class

I have a program where I use a class store settings. I need it to use set and get functions to change and store settings. I have tried this, and I don't get it to work. Can anyone help me with this one?

    private enum _Difficulty { Easy, Normal, Hard };

    public void SetDifficulty(Difficulty)
    {
        _Difficulty = Difficulty;
    }

    public enum GetDifficulty()
    {
        return _Difficulty;
    }

Is there no way to use enums in a class with get and set?

I also need this with bool and int.

Solution

There are several things wrong here:

Your enum is private, but your methods are public. Therefore you can't make your methods return type be the enum type, or have parameters with that type
Your SetDifficulty method has a parameter of just Difficulty - is that meant to be the parameter name or the type?
Your SetDifficulty method is trying to set the type rather than a field
Your GetDifficulty method is trying to use enum as a return type, and is then returning a type rather than a field

Basically, you seem to be confused about what your enum declaration is declaring - it's not declaring a field, it's declaring a type (and specifying what the named values of that type are).

I suspect you want:

// Try not to use nested types unless there's a clear benefit.
public enum Difficulty { Easy, Normal, Hard }

public class Foo
{
    // Declares a property of *type* Difficulty, and with a *name* of Difficulty
    public Difficulty Difficulty { get; set; }
}

You can use get/set methods if you really want to make your code look like Java instead of C#:

public enum Difficulty { Easy, Normal, Hard }

public class Foo
{
    private Difficulty difficulty;

    public void SetDifficulty(Difficulty value)
    {
        difficulty = value;
    }

    public Difficulty GetDifficulty()
    {
        return difficulty;
    }
}
