In the preceding code example, the range expression was an integer 1..4. In reality, they don’t have to be. In actual fact, they’re of a type called Index. The non-negative integer values convert to Index .

Because the range expression is of type Index, you can create an Index by using the new ^ operator.

Sometimes the new ^ operator is also referred to as the hat operator. Time will tell what is going to stick when referring to the ^ operator.

The new ^ operator means from-end, and so 1..^1 means 1 from the end. You can therefore have the following.string[] names = { "Dirk", "Jane", "James", "Albert", "Sally" };

foreach (var name in names[1..^1])

{

// do something

}
