Tuple (Of T1, T2, T3, T4, T5, T6, T7, TRest) In .NET Framework, the Tuple will directly support only 1 to 7 elements. The return type of a function establishes the size and type of the value returned by the function and corresponds to the type-specifier in the syntax below: Syntax. For example, this is a tuple type: type PersonProps = [string, number] const [name, age]: PersonProps = ['Stefan', 37] brightness_4 unity - return tuple c# . Structures in C. We can also use structures in C to return more than one value from the function.

Or in other words a method can return a tuple as shown in the below example: Example: filter_none. Tuple is an ordered sequence of heterogeneous objects. The type of each element is known (and does not have to be the same). That’s because you can return a tuple by separating each item with a comma, as shown in the above example. Tuple vs string en tant que clé de dictionnaire en C# (6) Je veux savoir quelle approche est la meilleure en termes de performance et de maintenabilité. Returning multiple values from a C++ function, Returning two values from a function in PHP. I would like to return two objects from a method using swift.
