C# | Tuple<T1,T2,T3,T4,T5> Class
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); } } |
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.." ); } } } |
Tuple Matched..
