Comparing and sorting Tuples C# with Example

Tuples can be compared based on their elements. 
As an example, an enumerable whose elements are of type Tuple can be sorted based on comparisons operators 
defined on a specified element: 
List> list = new List>(); 
list.Add(new Tuple(2, "foo")); 
list.Add(new Tuple(1, "bar")); 
list.Add(new Tuple(3, "qux")); 
list.Sort((a, b) => a.Item2.CompareTo(b.Item2)); //sort based  on the string element 
foreach (var element in list) { 
Console.WriteLine(element); 
} 
// Output: 
 

// (1, bar) 
// (2, foo) 
// (3, qux) 
Or to reverse the sort use: 
list.Sort((a, b) => b.Item2.CompareTo(a.Item2));
