string.Split Oddity

What's going on here?

Code:

string foo = "";
int i = foo.Split(new char[] {'*'}).Length;

The value of i is 1. Is this a bug or am i missing something?

No, this is not a bug. As far as the Split method is concerned, you have 1 zero length string in foo. If you made foo = "," you would have 2 zero length strings. You can tell the Split method to remove empty elements, it's the second parameter to the method (System.StringSplitOptions). This should then return a zero element array for an empty string.
