14 lis 2023 · Indexes and ranges provide clear, concise syntax to access a single element or a range of elements in a sequence. An index expression typically returns the type of the elements of a sequence. A range expression typically returns the same sequence type as the source sequence.
Using the built in Range struct (C# 8+), we can create an extension method to check if an Index is within the original range. public static bool IsInRangeOf(this Range range, Index index) { return index.Value >= range.Start.Value && index.Value < range.End.Value; }
