switch statement using an enum

Can you not use a straight enum in a switch statement?

It seems i have to cast it:

    public enum blah
    {
        p,b,s
    }

    public void dosomething(blah h)
    {
        switch (h)  // CANNOT DO THIS?
        {
            case 1:
                break;
            case 2:
                break;
            default:
                break;
        }


        switch ((int)h)  // THIS IS OKAY
        {
            case 1:
                break;
            case 2:
                break;
            default:
                break;
        }

    }

you can, but you have to use the enum names instead of numerical values in the case part...

 public void dosomething(blah h)

    {
        switch (h)  
        {
            case p:
                break;
            case b:
                break;
            default:
                break;
        }
