**SingleOrDefault** is similar to Single. On empty collections, it returns the default value for the type. With it you receive the single matching element, or the default value if no element is found.

```
using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace Prototype{    class Example    {
        static void Main()        {            int[] array = { 1, 2, 3,4,5,6,7,8,9 };            // Default is returned 0 if no element found.            int a = array.SingleOrDefault(element => element == 10);            Console.WriteLine(a);            // Value is returned if one is found.            int b = array.SingleOrDefault(element => element == 8);            Console.WriteLine(b);            Console.ReadLine();        }    }
}
```
