Tuple(Of T1) Class
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Represents a 1-tuple, or singleton.
Assembly: mscorlib (in mscorlib.dll)
The Tuple(Of T1) type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Equals | Returns a value that indicates whether the current Tuple(Of 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(Of 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(Of T1) instance. (Overrides Object.ToString.) |
| Name | Description | |
|---|---|---|
![]() ![]() | IComparable.CompareTo | Compares the current Tuple(Of 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(Of 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(Of T1) object is equal to a specified object based on a specified comparison method. |
![]() ![]() | IStructuralEquatable.GetHashCode | Calculates the hash code for the current Tuple(Of T1) object by using a specified computation method. |
A tuple is a data structure that has a specific number and sequence of values. The Tuple(Of 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(Of T1) object by calling either the Tuple(Of 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.
