You may also have a look at the following articles to learn more –, C# Training Program (6 Courses, 17 Projects). Also, the forwarding type is wrong, x is a tuple type and you need a tuple element type. Constructs an object of the appropriate tuple type to contain the elements specified in args. In a tuple, there are no names; a component is identified solely based on its position in the tuple. This allows a set of objects to act as a tuple, which is especially useful to unpack tuple objects. C# 4.x actually introduced the concept of a Tuple as part of dynamic programming techniques. Console.ReadLine(); C# provides a static Create method to create tuple as follows. The returning of the tuple from a method. Tuples in C# 7, provides a better mechanism to return multiple values from a method. The value tuple comes with .NET Framework 4.7 or .NET library 2.0. { And in the programming world, it is a very common thing to return multiple values from a method. In the following example, within the calculate method we create an instance of the Tuple class by calling the static Create method of the Tuple class. To make things even simpler, C++ offers not one but three helpers to build tuples and make our variadic template code more expressive: std::make_tuple, std::tie and std::forward_as_tuple.. All three reflect in their name the fact that they put values together to build … Tuple. Console.WriteLine(tuple.Item2.ToString()); The C++ 11 standard introduces a std::array which is equivalent to a traditional fixed length array, but is accessible through standard container methods.
