The Tuple<T1, T2, T3, T4, T5> class is used to create a 5-tuple or quintuple. It represents a tuple which contains the five elements in it. You can instantiate a Tuple<T1, T2, T3, T4, T5> object by calling either the Tuple<T1, T2, T3, T4, T5>(T1, T2, T3, T4, T5) constructor or by the static Tuple.Create method. You can retrieve the value of the tuple’s elements by using the read-only Item1, Item2, Item3, Item4, and Item5 instance property.
Important Points:
- It implements IStructuralComparable, IStructuralEquatable, and IComparable interface.
- It defined under System namespace.
- It represent multiple data into a single data set.
- It allows us to create, manipulate, and access data set.
- It returns multiple values from a method without using out parameter.
- It allows passing multiple values to a method with the help of single parameters.
- It can also store duplicate elements.
Constructor
| Constructor | Description |
|---|---|
| Tuple<T1, T2, T3, T4, T5>(T1, T2, T3, T4, T5) | Initializes a new instance of the Tuple<T1, T2, T3, T4, T5> class. |
Property
| Property | Description |
|---|---|
| Item1 | Gets the value of the Tuple<T1, T2, T3, T4, T5> object’s first component. |
| Item2 | Gets the value of the current Tuple<T1, T2, T3, T4, T5> object’s second component. |
| Item3 | Gets the value of the current Tuple<T1, T2, T3, T4, T5> object’s third component. |
| Item4 | Gets the value of the current Tuple<T1, T2, T3, T4, T5> object’s fourth component. |
| Item5 | Gets the value of the current Tuple<T1, T2, T3, T4, T5> object’s fifth component. |
Example:
// C# progtam to illustrate the constructor // and property of Tuple<T1, T2, T3, T4, T5> Class using System; class GFG { // Main Method static public void Main () { // Creating 5-Tuple // Using Tuple<T1, T2, T3, T4, // T5>(T1, T2, T3, T4, T5) constructor Tuple<int, int, int, string, int>mytuple = new Tuple<int, int, int, string, int>(79, 34, 67, "Geeks", 44); // Accessing the values Console.WriteLine("Value of the First Component: " + mytuple.Item1); Console.WriteLine("Value of the Second Component: " + mytuple.Item2); Console.WriteLine("Value of the Third Component: " + mytuple.Item3); Console.WriteLine("Value of the Fourth Component: " + mytuple.Item4); Console.WriteLine("Value of the Fifth Component: " + mytuple.Item5); } } |

Output:
Value of the First Component: 79 Value of the Second Component: 34 Value of the Third Component: 67 Value of the Fourth Component: Geeks Value of the Fifth Component: 44
Methods
| Method | Description |
|---|---|
| Equals(Object) | Returns a value that indicates whether the current Tuple<T1, T2, T3, T4, T5> object is equal to a specified object. |
| GetHashCode() | Returns the hash code for the current Tuple<T1, T2, T3, T4, T5> object. |
| GetType() | Gets the Type of the current instance. |
| MemberwiseClone() | Creates a shallow copy of the current Object. |
| ToString() | Returns a string that represents the value of this Tuple<T1, T2, T3, T4, T5> instance. |
Example:
// C# program to check whether the // given tuples are equal or not using System; class GFG { // Main method static public void Main() { // Creating 5-Tuple // Using Tuple<T1, T2, T3, T4, // T5>(T1, T2, T3, T4, T5) constructor Tuple<int, int, int, int, int> mytuple1 = new Tuple<int, int, int, int, int>(20, 40, 90, 89, 33); Tuple<int, int, int, int, int> mytuple2 = new Tuple<int, int, int, int, int>(20, 40, 90, 89, 33); // Using Equals method if (mytuple1.Equals(mytuple2)) { Console.WriteLine("Tuple Matched.."); } else { Console.WriteLine("Tuple not Matched.."); } } } |
