Enum values in a list

Question

I've a enum class like,

public enum USERTYPE
{
   Permanant=1,
   Temporary=2,
}

in my business object I just declare this enum as

private List<USERTYPE> userType=new List<USERTYPE>;

and in the get/set method, I tried like

public List<USERTYPE> UserType
    {
        get 
        {
            return userType;
        }
        set
        { 
            userType= value; 
        }
    }

here it returns the no of rows as 0, how can I get all the values in the Enum here, can anyone help me here...

You can use this to get all individual enum values:

private List<USERTYPE> userTypes = Enum.GetValues(typeof(USERTYPE)).Cast<USERTYPE>().ToList();

If you do things like this more often, you could create a generic utility method for it:

public static T[] GetEnumValues<T>() where T : struct {
    if (!typeof(T).IsEnum) {
        throw new ArgumentException("GetValues<T> can only be called for types derived from System.Enum", "T");
    }
    return (T[])Enum.GetValues(typeof(T));
}
