How to determine the no of enum items declared in c#

Question

I need to know the number of enums that have been declared. So far I am using the following which works but I wonder if there is a better way?

 enum MyEnum 
 {
  foo = 1,
  bar = 2
 }

int noOfEnums = Enum.GetNames(typeof(MyEnum)).Count();

noOfEnums will be 2;

`Enum.GetNames(typeof(MyEnum)).Length` is slightly better. :) — Dmitry, Apr 16 '14 at 10:08
Because the length of an array is not calculated each time you access it in contrast with enumerating an `IEnumerable`. — Dmitry, Apr 16 '14 at 10:16

You may try to use:

enum MyEnum 
{
  foo = 1,
  bar = 2
}

var noOfEnums = Enum.GetNames(typeof(MyEnum)).Length;

The length property of this array equals the number of items defined in the enum
