Convert an Enum Array into an Interger Array

DayOfWeek[] enumArray = new DayOfWeek[] { 
    DayOfWeek.Monday, DayOfWeek.Wednesday };

//Convert enum to int array
int[] result = Array.ConvertAll<DayOfWeek, int>(enumArray,
    delegate(DayOfWeek value) { return (int)value; });

//with C# 3.0, a lambda:
int[] result2 = Array.ConvertAll(enumArray, value => (int) value);

//with C# 3.0 using Cast
int[] result3 = enumArray.Cast<int>().ToArray();
