Examples of C # tuples are detailed

Summary of tuples:

Arrays combine objects of the same type, and tuples combine different types of objects. Tuples originate from functional programming languages (such as F #),
Tuples are frequently used in these languages. In N-Stare 4, tuples can be used with. NET fmmework for all NET languages.
. NET 4 defines 8 generic tuple classes and a static tuple class that are used as a factory for tuples. Here are the different generic tuple
class supports a different number of elements. For example,tuple<t1> contains an element,tuple<t1,t2> contains two elements, and so on.

1. A first example

Private Tuple<int, int> Divide (int dividend, int divisor)
{
int result = Dividend/divisor;
int reminder = dividend% divisor;
Return tuple.create<int, int> (result, reminder); Returns a tuple of two elements of the same type
}

--------Test-------------

private void Button1_Click (object sender, EventArgs e)
{
Tuple<int, int> result = Divide (13, 2);
Console.WriteLine ("Result of divison:{0}," +
"Reminder:{1}", result. ITEM1, result.                ITEM2); Accessing tuples ' items with property item1,item2
}

-------Results-------------

Result of Divison:6,reminder:1

2. A second example

Private Tuple<int, string> MyTest2 (int dividend, string Name)
{
int result = DIVIDEND/2;
String name = "Hello," + name;
Return tuple.create<int, string> (result, name); Returns a tuple of two different types of elements
}

--------Test-------------

private void Button2_Click (object sender, EventArgs e)
{
Tuple<int, string> result = MyTest2 ("Limin");
Console.WriteLine ("Result of divison:{0}," +
"Name:{1}", result. ITEM1, result.                ITEM2); Accessing tuples ' items with property item1,item2
}

-------Results-------------

Result of Divison:6,name:hello,limin

3. A third example

If a tuple contains more than 8 items, you can use a tuple class definition with 8 parameters. The last template parameter is trest,
Indicates that a tuple must be passed to it. This allows you to create a tuple with any parameters.
This feature is described below:
public class Tuple<t1,t2,t3,t4,t5,t6,t7,trest>
Where the last template parameter is a tuple type, you can create tuples with any number of items:
var tuple = tuple.create<string,string,string, int,int,int,double,
Tuple<int,int>> (
"Stephanie", "Alina", "Nagel", 2009,6,2,1.37,
Tuple.create<int,int> (52,3490));
