Tuple Class in C#
The Tuple<T1, T2, T3, T4, T5> class represents a 5-tuple, which is called quintuple. 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
It has five properties −
Item1− Get the value of the current Tuple<T1, T2, T3, T4, T5> object's first component.
Item2− Get the value of the current Tuple<T1, T2, T3, T4, T5> object's second component.
Item3− Get the value of the current Tuple<T1, T2, T3, T4, T5> object's third component.
Item4− Get the value of the current Tuple<T1, T2, T3, T4, T5> object's fourth component.
Item5− Get the value of the current Tuple<T1, T2, T3, T4, T5> object's fifth component.
Let us now see an example to implement the 5-tuple in C# −
Example
using System;
public class Demo {
public static void Main(string[] args) {
Tuple<int,int,int,int,int> tuple = new Tuple<int,int,int,int,int>(120, 150, 270, 300, 600);
Console.WriteLine("Value (Item1)= " + tuple.Item1);
Console.WriteLine("Value (Item2)= " + tuple.Item2);
Console.WriteLine("Value (Item3)= " + tuple.Item3);
Console.WriteLine("Value (Item4)= " + tuple.Item4);
Console.WriteLine("Value (Item5)= " + tuple.Item5);
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);
}
if (tuple.Item5 == 400) {
Console.WriteLine("Exists: Tuple Item 5 = " +tuple.Item5);
}
}
}Output
This will produce the following output −
Value (Item1)= 100 Value (Item2)= 150 Value (Item3)= 300 Value (Item4)= 450 Value (Item5)= 600 Exists: Tuple Item 1 = 100
Let us now see another example to implement the 5-tuple in C# −
Example
using System;
public class Demo {
public static void Main(string[] args) {
Tuple<string,int,string,int,int> tuple = new Tuple<string,int,string,int,int>("jack", 150, "pete", 300, 600);
Console.WriteLine("Value (Item1)= " + tuple.Item1);
Console.WriteLine("Value (Item2)= " + tuple.Item2);
Console.WriteLine("Value (Item3)= " + tuple.Item3);
Console.WriteLine("Value (Item4)= " + tuple.Item4);
Console.WriteLine("Value (Item5)= " + tuple.Item5);
if (tuple.Item1 == "kevin") {
Console.WriteLine("Exists: Tuple Item 1 = " +tuple.Item1);
}
if (tuple.Item2 == 250) {
Console.WriteLine("Exists: Tuple Item 2 = " +tuple.Item2);
}
if (tuple.Item3 == "pete") {
Console.WriteLine("Exists: Tuple Item 3 = " +tuple.Item3);
}
if (tuple.Item4 == 300) {
Console.WriteLine("Exists: Tuple Item 4 = " +tuple.Item4);
}
if (tuple.Item5 == 400) {
Console.WriteLine("Exists: Tuple Item 5 = " +tuple.Item5);
}
}
}Output
This will produce the following output −
Value (Item1)= jack Value (Item2)= 150 Value (Item3)= pete Value (Item4)= 300 Value (Item5)= 600 Exists: Tuple Item 3 = pete Exists: Tuple Item 4 = 300
