Attributes

Implements

A tuple is a data structure that has a specific number and sequence of values. The Tuple<T1,T2,T3,T4,T5,T6,T7> class represents a 7-tuple, or septuple, which is a tuple that has seven components.

You can instantiate a Tuple<T1,T2,T3,T4,T5,T6,T7> object by calling either the Tuple<T1,T2,T3,T4,T5,T6,T7> or the static Tuple.Create<T1,T2,T3,T4,T5,T6,T7>(T1, T2, T3, T4, T5, T6, T7) method. You can retrieve the value of the tuple's components by using the read-only Item1, Item2, Item3, Item4, Item5, Item6, and Item7 instance properties.

Tuples are commonly used in four different ways:

using System;

Constructors

Tuple<T1,T2,T3,T4,T5,T6,T7>(T1, T2, T3, T4, T5, T6, T7) Initializes a new instance of the Tuple<T1,T2,T3,T4,T5,T6,T7> class.

Properties

Item1 Gets the value of the current Tuple<T1,T2,T3,T4,T5,T6,T7> object's first component.
Item2 Gets the value of the current Tuple<T1,T2,T3,T4,T5,T6,T7> object's second component.
Item3 Gets the value of the current Tuple<T1,T2,T3,T4,T5,T6,T7> object's third component.
Item4 Gets the value of the current Tuple<T1,T2,T3,T4,T5,T6,T7> object's fourth component.
Item5 Gets the value of the current Tuple<T1,T2,T3,T4,T5,T6,T7> object's fifth component.
Item6 Gets the value of the current Tuple<T1,T2,T3,T4,T5,T6,T7> object's sixth component.
Item7 Gets the value of the current Tuple<T1,T2,T3,T4,T5,T6,T7> object's seventh component.

Methods

Equals(Object) Returns a value that indicates whether the current Tuple<T1,T2,T3,T4,T5,T6,T7> object is equal to a specified object.
GetHashCode() Returns the hash code for the current Tuple<T1,T2,T3,T4,T5,T6,T7> object.
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,T2,T3,T4,T5,T6,T7> instance.

Explicit Interface Implementations

IComparable.CompareTo(Object) Compares the current Tuple<T1,T2,T3,T4,T5,T6,T7> 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(Object, IComparer) Compares the current Tuple<T1,T2,T3,T4,T5,T6,T7> 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(Object, IEqualityComparer) Returns a value that indicates whether the current Tuple<T1,T2,T3,T4,T5,T6,T7> object is equal to a specified object based on a specified comparison method.
IStructuralEquatable.GetHashCode(IEqualityComparer) Calculates the hash code for the current Tuple<T1,T2,T3,T4,T5,T6,T7> object by using a specified computation method.
ITuple.Item[Int32] Gets the value of the specified Tuple element.
ITuple.Length Gets the number of elements in the Tuple.

Extension Methods

Deconstruct<T1,T2,T3,T4,T5,T6,T7>(Tuple<T1,T2,T3,T4,T5,T6,T7>, T1, T2, T3, T4, T5, T6, T7) Deconstructs a tuple with 7 elements into separate variables.
ToValueTuple<T1,T2,T3,T4,T5,T6,T7>(Tuple<T1,T2,T3,T4,T5,T6,T7>) Converts an instance of the Tuple class to an instance of the ValueTuple structure.
