Represents a 1-tuple, or singleton.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
[SerializableAttribute]
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.

Explicit interface implemetationPrivate methodIStructuralComparable.CompareToCompares 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.
Explicit interface implemetationPrivate methodIStructuralEquatable.EqualsReturns a value that indicates whether the current Tuple<T1> object is equal to a specified object based on a specified comparison method.

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.
