tuple variable name code example

Example 1: c# initialize tuple with default values

(double, int) t1 = (4.5, 3);
Console.WriteLine($"Tuple with elements {t1.Item1} and {t1.Item2}.");
// Output:
// Tuple with elements 4.5 and 3.

(double Sum, int Count) t2 = (4.5, 3);
Console.WriteLine($"Sum of {t2.Count} elements is {t2.Sum}.");
// Output:
// Sum of 3 elements is 4.5.

Example 2: c# tuple

var tupleList = new List<Tuple<int, string, string, string>>();
 tupleList.Add(Tuple.Create(1, "Sefat Anam", "Dhaka Bangladesh", "0.1245345"));

Example 3: tuple parameter name

// Tuples cannot be assigned parameter names.
//Instead you could do something like this:

(string name, int id) user = ("jack", 1);
Console.WriteLine($"{user.name}, {user.id}");
// Output:
//	jack, 1

// When working with lists:

List<(string name, int id)> users = new List<(string, int)>();

users.Add(("jack", 1));
users.Add(("john", 2));

users.ForEach((x) =>
	Console.WriteLine($"{x.name}, {x.id}")):

// Output:
//	jack, 1
//	john, 2
