Trick of the trade – set enum to not zero
When defining enums set the first of the items to a non-zero value.
This way one knows whether one has forgotten to set the value.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | using System; public class Program { private static int SomeNonInitiatedValueFromSomewhere = 0; public enum MyEnum { AnItem = 1, AnotherItem } public static void Main() { var myEnum = MyEnum.AnotherItem; MyEnum myForgottenEnum = (MyEnum)SomeNonInitiatedValueFromSomewhere; Console.WriteLine("Now={0}", DateTime.Now.ToString("HH:mm")); Console.WriteLine("myEnum={0}", myEnum); // This enum is set. Console.WriteLine("myForgottenEnum={0}", myForgottenEnum); // This enum is not set. } } |
