Quickest way to enumerate the alphabet

Question

I want to iterate over the alphabet like so:

foreach(char c in alphabet)
{
 //do something with letter
}

Is an array of chars the best way

Answer 1

I found this:

foreach(char letter in Enumerable.Range(65, 26).ToList().ConvertAll(delegate(int value) { return (char)value; }))
{
//breakpoint here to confirm
}

while randomly reading this blog, and thought it was an interesting way to accomplish the task.
