Tuple Class in C#
The Tuple<T1, T2> class represents a 2-tuple, which is called pair. 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 two properties −
Item1 − Get the value of the current Tuple<T1, T2> object's first component.
Item2 − Get the value of the current Tuple<T1, T2> object's second component.
Example
Let us now see an example to implement the 2-tuple in C# −
using System;
public class Demo {
public static void Main(string[] args) {
Tuple<string,string> tuple = new Tuple<string,string>("jack", "steve");
Console.WriteLine("Value = " + tuple.Item1);
if (tuple.Item1 == "jack") {
Console.WriteLine("Exists: Tuple Value = " +tuple.Item1);
}
if (tuple.Item2 == "david") {
Console.WriteLine("Exists: Tuple Value = " +tuple.Item2);
}
}
}Output
This will produce the following output −
Value = jack Exists: Tuple Value = jack
Example
Let us now see another example to implement the 2-tuple in C# −
using System;
public class Demo {
public static void Main(string[] args) {
Tuple<int,string> tuple = new Tuple<int,string>(20, "steve");
Console.WriteLine("Value = " + tuple.Item1);
if (tuple.Item1 == 20) {
Console.WriteLine("Exists: Tuple Value = " +tuple.Item1);
}
if (tuple.Item2 == "david") {
Console.WriteLine("Exists: Tuple Value = " +tuple.Item2);
}
}
}Output
This will produce the following output −
Value = 20 Exists: Tuple Value = 20
