C# | Tuple<T1> Class
The Tuple<T1> class is used to create 1-tuple or singleton which contains only a single element in it. You can instantiate a Tuple <T1> object by calling either the Tuple<T1> constructor or by the static Tuple.Create method. You can retrieve the value of the tuple’s single element by using the read-only Item1 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>(T1) | Initializes a new instance of the Tuple<T1> class. |
Property
Property | Description |
---|---|
Item1 | Gets the value of the Tuple<T1> object’s single element. |
Example:
// C# program to illustrate the constructor // and property of class Tuple<T1> using System; class GFG { // Main method static public void Main() { // Creating 1-Tuple // Using Tuple<T1>(T1) Tuple< int > mytuple = new Tuple< int >(22); // Accessing the values Console.WriteLine( "Value of the Element is: " + mytuple.Item1); } } |
Output:
Value of the Element is: 22
Methods
Method | Description |
---|---|
Equals(Object) | Returns a value that indicates whether the current Tuple<T1> object is equal to a specified object. |
GetHashCode() | Returns the hash code for the current Tuple<T1> 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> instance. |
Example:
// C# program to determine the // given tuples are equal or not using System; class GFG { // Main method static public void Main() { // Creating 1-Tuple // Using Tuple<T1>(T1) Tuple< int > mytuple1 = new Tuple< int >(22); Tuple< int > mytuple2 = new Tuple< int >(22); // Using Equals method if (mytuple1.Equals(mytuple2)) { Console.WriteLine( "Tuple Matched.." ); } else { Console.WriteLine( "Tuple not matched.." ); } } } |
Output:
Tuple Matched..
