Tuples in C#

 

Tuples (ValueTuple in modern C#) are data structures that are lightweight and enable the grouping of multiple values of varying types into a single object without the necessity of defining a custom class or struct. They pertain to the returning or temporarily holding multiple related pieces of data.
