I have come across many instances where I wanted to return more than one value from a method. As Mads Torgersen pointed out, the existing options available to developers are not optimal. C# 7.0 has, therefore, introduced Tuple types and Tuple literals to allow developers an easy way of returning multiple values from methods. Developers can also rest easy when creating Tuples. Tuples are structs, which are value types. This means that they are created locally and are passed by copying the contents. Tuples are also mutable and Tuple elements are public mutable fields. I am personally very excited about using Tuples. Let's explore Tuples in closer detail in the following recipe.
