Array is immutable object. So, you can't remove from array. You can create new array without this value using LINQ:

values = values.Where(o=> o != "2").ToArray();

Or, you can create List and remove from list:

List<string> values = User.Split(';').ToList();
values.Remove("2");

Try this:

myArray = myArray.Where(w => w != myArray[2]).ToArray();

you can't be sure, that myArray[2] == "2"
