2. TUPLE
 A tuple is a data structure that has a specific number and
sequence of elements.
 An example of a tuple is a data structure with three elements
(known as a 3-tuple or triple) that is used to store an identifier
such as a person's name in the first element, a year in the second
element, and the person's income for that year in the third
element.
 The .NET Framework directly supports tuples with one to seven
elements.
 In addition, you can create tuples of eight or more elements by
nesting tuple objects in the Rest property of a Tuple<T1, T2, T3,
T4, T5, T6, T7, TRest> object.

3. TUPLE
 Provides static methods for creating tuple objects.

4. TUPLE EXAMPLE


5. TUPLES ARE COMMONLY USED IN FOUR
WAYS
 To represent a single set of data. For example, a tuple can
represent a database record, and its components can represent
individual fields of the record.
 To provide easy access to, and manipulation of, a data set.
 To return multiple values from a method without using out
parameters (in C#) or ByRef parameters (in Visual Basic).
 To pass multiple values to a method through a single parameter.

6. TUPLE<T1, T2, T3, T4, T5, T6, T7,
TREST>
 Represents an n-tuple, where n is 8 or greater.
 TRest
 Any generic Tuple object that defines the types of the tuple's remaining
components.
