Question

I have an enum

enum myEnum2 { ab, st, top, under, below}

I would like to write a function to test if a given value is included in myEnum

something like that:

private bool EnumContainValue(Enum myEnum, string myValue)
{
     return Enum.GetValues(typeof(myEnum))
                .ToString().ToUpper().Contains(myValue.ToUpper()); 
}

But it doesn’t work because myEnum parameter is not recognized.

No need to write your own:

    // Summary:
    //     Returns an indication whether a constant with a specified value exists in
    //     a specified enumeration.
    //
    // Parameters:
    //   enumType:
    //     An enumeration type.
    //
    //   value:
    //     The value or name of a constant in enumType.
    //
    // Returns:
    //     true if a constant in enumType has a value equal to value; otherwise, false.

    public static bool IsDefined(Type enumType, object value);

Example:

if (System.Enum.IsDefined(MyEnumType, MyValue))
{
    // Do something
}
