Check that integer type belongs to enum member

Question

I want to check that some integer type belongs to (an) enumeration member.

For Example,

public enum Enum1
{
    member1 = 4,

    member2 = 5,

    m         


        

Answer 1

You look through the values of the enum and compare them to the integer.

    static bool EnumTest(int testVal, Enum e)
    {
        bool result = false;
        foreach (var val in Enum.GetValues(typeof(Enum1)))
        {
            if ((int)val == testVal)
            {
                result = true;
                break;
            }
        }
        return result;
    }

Edit: Looks like Sam has a better solution.
