بازهها و الگوهای بازگشتی در C# 8
- C# 8 Adds Ranges and Recursive Patterns
- Ranges easily define a sequence of data, replacing the Enumberable.Range()
- Recursive Patterns brings an F#-like construct to C#
- Recursive Patterns is an awesome feature, it giving you the flexibility to testing the data against a sequence of conditions and performing further computations based on the condition met.
- Ranges is very useful to generate sequences of numbers in the form of a collection or a list.
