Passing a ValueTuple return type as an argument.

Guest User

I am interested in retrieving a tuple of multiple values from a class method and then passing that result directly to another class method. See example code to see what I intend (it does not compile):

Edit: I realize that I could use "(double, double) myVar" as the parameter and then use myVar.Item1, and myVar.Item2, but I would prefer to be able to use the terms that I define and not something so generic.

class ClassA
{
public static (double, double) GetTuple()
{
return (12.5, 13.5);
}
}
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
ClassB.ShowTuple(ClassA.GetTuple());
}
}
public static class ClassB
{
public static void ShowTuple((double myVar1, double myVar2))
{
Console.WriteLine(myVar1);
Console.WriteLine(myVar2);
}
}

The problem appears to be in ClassB with the parameter passed to ShowTuple. I tried it without the extra parenthesis, as a Tuple, ValueTuple, etc., but nothing seems to work.

Does anyone know what I am missing?

Thanks!

Hi Boris, I have fixed your issue check it.
using System;
namespace Tuples
{
    public class Program
    {
        static void Main(string[] args)
        {
            ClassB.ShowTuple(ClassA.GetTuple());
            Console.ReadKey();
        }
    }
}
public static class ClassA
{
    public static Tuple<double, double> GetTuple()
    {
        return Tuple.Create(12.5, 13.5);
    }
}
public static class ClassB
{
    public static void ShowTuple(Tuple<double, double> printValues)
    {
        Console.WriteLine($"myVar1 = {printValues.Item1}");//you can use printValues.Item1 directly
        Console.WriteLine($"myVar2 = {printValues.Item2}");// do
    }
}
