In C#, Tuple class is used to provide static methods for creating tuples and this class defined under System namespace. This class itself does not represent a tuple, but it provides static methods that are used to create an instance of the tuple type. Or in other words, the Tuple class provides helper methods that are used to instantiate tuple objects without having to explicitly specify the type of each tuple component. In tuple, you can only store elements from one to eight, if you try to store elements greater than eight without nested tuple, then the compiler will give an error.
Generally, tuples are used:
- To represent multiple data into a single data set.
- To create, manipulate, and access data set.
- To return multiple values from a method without using out parameters.
- To pass multiple values to a method with the help of single parameters.
Note: You can also, create a tuple with the help of the constructors which are provided by tuple classes, but in constructors, you have to specify the type of the elements present in the tuple as shown in the below example:
Element 1: 22 Element 2: 334 Element 3: 54 Element 4: 65 Element 5: 76 Element 6: 87 Element 7: 98
|Create <T1>(T1)||Creates a new 1-tuple, or singleton.|
|Create <T1, T2>(T1, T2)||Creates a new 2-tuple, or pair.|
|Create <T1, T2, T3>(T1, T2, T3)||Creates a new 3-tuple, or triple.|
|Create <T1, T2, T3, T4>(T1, T2, T3, T4)||Creates a new 4-tuple, or quadruple.|
|Create <T1, T2, T3, T4, T5>(T1, T2, T3, T4, T5)||Creates a new 5-tuple, or quintuple.|
|Create <T1, T2, T3, T4, T5, T6>(T1, T2, T3, T4, T5, T6)||Creates a new 6-tuple, or sextuple.|
|Create <T1, T2, T3, T4, T5, T6, T7>(T1, T2, T3, T4, T5, T6, T7)||Creates a new 7-tuple, or septuple.|
|Create <T1, T2, T3, T4, T5, T6, T7, TRest>(T1, T2, T3, T4, T5, T6, T7, T8)||Creates a new 8-tuple, or octuple.|
