Tuple Class in C#
The Tuple<T1,T2,T3,T4,T5,T6,T7> class represents a 7-tuple, which is called septet. 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 seven properties −
Item1− Get the value of the current Tuple<T1,T2,T3,T4,T5,T6,T7> object's first component.
Item2− Get the value of the current Tuple<T1,T2,T3,T4,T5,T6,T7> object's second component.
Item3− Get the value of the current Tuple<T1, T2, T3, T4, T5, T6, T7> object's third component.
Item4− Get the value of the current Tuple<T1,T2,T3,T4,T5,T6,T7>object's fourth component.
Item5− Get the value of the current Tuple<T1,T2,T3,T4,T5,T6,T7> object's fifth component.
Item6− Get the value of the current Tuple<T1,T2,T3,T4,T5,T6,T7> object's sixth component.
Item7− Get the value of the current Tuple<T1,T2,T3,T4,T5,T6,T7> object's seventh component.
Let us now see an example to implement the 7-tuple in C# −
Example
using System;
public class Demo {
public static void Main(string[] args) {
Tuple<int,int,int,int,int,int,int> tuple = new Tuple<int,int,int,int,int,int,int>(100, 150, 200, 300, 600, 1000, 2000);
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);
Console.WriteLine("Value (Item6)= " + tuple.Item6);
Console.WriteLine("Value (Item7)= " + tuple.Item7);
if (tuple.Item5 == 600) {
Console.WriteLine("Exists: Tuple Item 5 = " +tuple.Item5);
}
if (tuple.Item6 == 900) {
Console.WriteLine("Exists: Tuple Item 6 = " +tuple.Item6);
}
if (tuple.Item7 == 2000) {
Console.WriteLine("Exists: Tuple Item 7 = " +tuple.Item7);
}
}
}Output
This will produce the following output −
Value (Item1)= 100 Value (Item2)= 150 Value (Item3)= 200 Value (Item4)= 300 Value (Item5)= 600 Value (Item6)= 1000 Value (Item7)= 2000 Exists: Tuple Item 5 = 600 Exists: Tuple Item 7 = 2000
Let us now see another example to implement the 7-tuple in C# −
Example
using System;
public class Demo {
public static void Main(string[] args) {
Tuple<int,int,int,int,int,int,int> tuple = new Tuple<int,int,int,int,int,int,int>(100, 150, 200, 300, 600, 1000, 1000);
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);
Console.WriteLine("Value (Item6)= " + tuple.Item6);
Console.WriteLine("Value (Item7)= " + tuple.Item7);
if (tuple.Item5 == 600) {
Console.WriteLine("Exists: Tuple Item 5 = " +tuple.Item5);
}
if (tuple.Item6 == 900) {
Console.WriteLine("Exists: Tuple Item 6 = " +tuple.Item6);
}
if (tuple.Item7 == 2000) {
Console.WriteLine("Exists: Tuple Item 7 = " +tuple.Item7);
}
if (tuple.Item7 == tuple.Item6){
Console.WriteLine("Tuple Items Matched!");
}
}
}Output
This will produce the following output −
Value (Item1)= 100 Value (Item2)= 150 Value (Item3)= 200 Value (Item4)= 300 Value (Item5)= 600 Value (Item6)= 1000 Value (Item7)= 1000 Exists: Tuple Item 5 = 600 Tuple Items Matched!
