How to create 4-Tuple or quadruple in C#?
The Tuple<T1, T2, T3, T4> class represents a 4-tuple, which is called quadruple. A tuple is a data structure that has a sequence of elements.
It is used in −
- Easier access to a data set.
- Easier manipulation of a data set.
- To represent a single set of data.
- To return multiple values from a method
- To pass multiple values to a method
Example
Let us now see an example to implement the 4-tuple in C# −
using System;
public class Demo {
public static void Main(string[] args) {
Tuple<string,string,string,string> tuple = new Tuple<string,string,string,string>("nathan", "steve", "katie", "tim");
Console.WriteLine("Value (Item1)= " + tuple.Item1);
Console.WriteLine("Value (Item2)= " + tuple.Item2);
Console.WriteLine("Value (Item3)= " + tuple.Item3);
Console.WriteLine("Value (Item4)= " + tuple.Item4);
if (tuple.Item1 == "nathan") {
Console.WriteLine("Exists: Tuple Value = " +tuple.Item1);
}
if (tuple.Item2 == "jack") {
Console.WriteLine("Exists: Tuple Value = " +tuple.Item2);
}
if (tuple.Item3 == "katie") {
Console.WriteLine("Exists: Tuple Value = " +tuple.Item3);
}
if (tuple.Item4 == "tom") {
Console.WriteLine("Exists: Tuple Value = " +tuple.Item4);
}
}
}Output
This will produce the following output −
Value (Item1)= nathan Value (Item2)= steve Value (Item3)= katie Value (Item4)= tom Exists: Tuple Value = nathan Exists: Tuple Value = katie
Example
Let us now see another example to implement the 4-tuple in C# −
using System;
public class Demo {
public static void Main(string[] args) {
Tuple<int,int,int,int> tuple = new Tuple<int,int,int,int>(100, 150, 300, 450);
Console.WriteLine("Value (Item1)= " + tuple.Item1);
Console.WriteLine("Value (Item2)= " + tuple.Item2);
Console.WriteLine("Value (Item3)= " + tuple.Item3);
Console.WriteLine("Value (Item4)= " + tuple.Item4);
if (tuple.Item1 == 100) {
Console.WriteLine("Exists: Tuple Item 1 = " +tuple.Item1);
}
if (tuple.Item2 == 250) {
Console.WriteLine("Exists: Tuple Item 2 = " +tuple.Item2);
}
if (tuple.Item3 == 270) {
Console.WriteLine("Exists: Tuple Item 3 = " +tuple.Item3);
}
if (tuple.Item4 == 300) {
Console.WriteLine("Exists: Tuple Item 4 = " +tuple.Item4);
}
}
}Output
This will produce the following output −
Value (Item1)= 100 Value (Item2)= 150 Value (Item3)= 300 Value (Item4)= 450 Exists: Tuple Item 1 = 100
