C# | Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> Class

The Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> class is a generic class in the C# programming language that represents a tuple, or an ordered set of values. It is a part of the System namespace, and can be used to group together multiple values of different types.

Syntax

The syntax for creating an instance of the Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> class is as follows:

Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> name = new Tuple<T1,T2,T3,T4,T5,T6,T7,TRest>(value1, value2, value3, value4, value5, value6, value7, values);

• T1, T2, T3, T4, T5, T6, T7, and TRest are the generic type parameters for the tuple. They represent the types of the elements in the tuple.
• name is the name of the tuple.
• value1, value2, value3, value4, value5, value6, and value7 are the values of the first seven elements in the tuple.
• values is the value of the rest of the elements in the tuple.

Example

Here is an example of how to create a tuple using the Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> class:

Tuple<int, string, bool, double, int, string, int, int[]> tuple = new Tuple<int, string, bool, double, int, string, int, int[]>(1, "Hello", true, 3.14, 2, "World", 3, new int[] { 4, 5, 6 });

This creates a tuple with the following elements:

• int with a value of 1
• string with a value of "Hello"
• bool with a value of true
• double with a value of 3.14
• int with a value of 2
• string with a value of "World"
• int with a value of 3
• int[] with values of 4, 5, 6

Properties

The Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> class has several properties that can be used to access its elements:

• Item1 - Gets or sets the value of the first element in the tuple.
• Item2 - Gets or sets the value of the second element in the tuple.
• Item3 - Gets or sets the value of the third element in the tuple.
• Item4 - Gets or sets the value of the fourth element in the tuple.
• Item5 - Gets or sets the value of the fifth element in the tuple.
• Item6 - Gets or sets the value of the sixth element in the tuple.
• Item7 - Gets or sets the value of the seventh element in the tuple.
• Rest - Gets or sets the value of the rest of the elements in the tuple.

Conclusion

The Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> class is a useful tool for grouping together multiple values of different types in C#. By using this class, programmers can easily group together related data and pass it around as a single object.
