Represents a 1-tuple, or singleton.

Inheritance Hierarchy

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Class Tuple(Of T1) _
    Implements IStructuralEquatable, IStructuralComparable, IComparable

public class Tuple<T1> : IStructuralEquatable, IStructuralComparable, 
    IComparable

Type Parameters

T1
The type of the tuple's only component.

The Tuple<T1> type exposes the following members.

Constructors

	Name	Description
	Tuple<T1>	Initializes a new instance of the Tuple<T1> class.

Properties

	Name	Description
	Item1	Gets the value of the Tuple<T1> object's single component.

Methods

	Name	Description
	Equals	Returns a value that indicates whether the current Tuple<T1> object is equal to a specified object. (Overrides Object.Equals(Object).)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Returns the hash code for the current Tuple<T1> object. (Overrides Object.GetHashCode().)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the value of this Tuple<T1> instance. (Overrides Object.ToString().)

Explicit Interface Implementations

	Name	Description
	IComparable.CompareTo	Compares the current Tuple<T1> object to a specified object, and returns an integer that indicates whether the current object is before, after, or in the same position as the specified object in the sort order.
	IStructuralComparable.CompareTo	Compares the current Tuple<T1> object to a specified object by using a specified comparer, and returns an integer that indicates whether the current object is before, after, or in the same position as the specified object in the sort order.
	IStructuralEquatable.Equals	Returns a value that indicates whether the current Tuple<T1> object is equal to a specified object based on a specified comparison method.
	IStructuralEquatable.GetHashCode	Calculates the hash code for the current Tuple<T1> object by using a specified computation method.

Remarks

A tuple is a data structure that has a specific number and sequence of values. The Tuple<T1> class represents a 1-tuple, or singleton, which is a tuple that has a single component. A singleton is used comparatively rarely in application development.

You can instantiate a Tuple<T1> object by calling either the Tuple<T1> constructor or the static Tuple.Create method. You can retrieve the value of the tuple's single component by using the read-only Item1 instance property.
