A Tuple is a data structure that comprises an ordered, finite sequence of immutable, heterogeneous elements of fixed sizes. When we say the elements in a Tuple are immutable, we mean that they pertain to a specific type that cannot be changed.
A ValueTuple is a structure introduced in C# 7.0. A ValueTuple overcomes two major limitations of tuples—namely, that they are inefficient and that they must be referenced as Item1, Item2, etc. That is, ValueTuples are both performant and referenceable by names the programmer chooses. This article discusses what ValueTuples are and how we can use them in C#.
