Simple Tuple Example

A Tuple has many items.Each item can have any type.Basically a Tuple is an ordered sequence,immutable,fixed-size and of heterogeneous objects,i.e., each object being of a specific type.It's an static class.It's introduced in C#-4.0.
We access the tuple properties by items.
We can understand it with an example:-

Tuple<int,string,bool> tuple_name = new Tuple<int,string,bool>(5,"Rajesh",true);

// Now Access tuple properties.
if (tuple_name.Item1 == 5)
{
    Response.Write(tuple_name.Item1);
}
if (tuple_name.Item2 == "Rajesh")
{
    Response.Write(tuple_name.Item2);
}
if (tuple_name.Item3)
{
    Response.Write(tuple_name.Item3);
}

Output:
5
Rajesh
True

//Another tuple example

public Tuple<int,int> GetAdditionAndSubtraction(int a, int b) 
{ 
    Tuple.Create(a+b,a-b); 
} 

public void Get_Result() 
{ 
    var tuple_number = GetAdditionAndSubtraction(5,5); 
    Response.Write(tuple_number.item1); 
    Response.Write(tuple_number.item2); 
}
