C# Tuple

-       If you need quickly to  :

o   Pass multiple values to a method through a single parameter.

o   to return multiple values from a method without using out parameters

-       Tuple type is a class. Once we create the Tuple, we cannot change the values of its fields.

Example1:

Tuple<int, string> tuple = new Tuple<int, string>(33, "NADY");

Example2:

Tuple has 8 overloads and each of these overloads returns new object of Tuple<t1, t2...t8> class.  

However, if you write:

Tuple<int, string, int, int, int, int, int, int> tuple =

new Tuple<int, string, int, int, int, int, int, int>(33, "NADY", 39, 39, 59, 49, 30, 33);

-       You will get ArgumentException

-       Therefore, you should pass the last generic argument 8th as Tuple. Using this argument, you can create as many arguments as you want. 

-       Tuple<int, string, int, int, int, int, int, Tuple<int>> tuple =

new Tuple<int, string, int, int, int, int, int, Tuple<int>>(20, "NADY", 39, 39, 59, 49, 30, new Tuple<int>(33));

 

Result As CSV:

If you use ToString with Tuple objects, it will return comma separated string with braces around it.
