Question

say i have an enum

public myEnum
{
   value1, value2

}

if I have an integer, can I see if it exists within myEnum?

Answer 1

Use Enum.IsDefined(). The full definition is

public static bool IsDefined(
    Type enumType,
    Object value
)

Example usage:

public enum MyEnum { A = 1, B = 2 };

Enum.IsDefined(typeof(MyEnum), 1) --> true
Enum.IsDefined(typeof(MyEnum), 3) --> false
