# Use  Union operator in Linq.

We want to use [Union](https://www.mindstick.com/articles/1510/union-example-in-sql-server) [operator](https://www.mindstick.com/blog/144/union-intersection-and-except-operator-in-sql-server) in Linq. How to use this please help me.

The Union extension method requires two collections, one collection on which the Union method is invoked and a second collection,\
which is passed as a parameter. The Union method returns distinct elements from both the collections.

```
using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace Prototype{
    class Example    {        static void Main()        {            IList<string> List1 = new List<string>() { "aditya", "manoj", "komal", "karan", "tarun" };            IList<string> List2 = new List<string>() { "tarun", "ajay", "vimal", "vijay", "manoj" };            var result = List1.Union(List2);
            foreach (string str in result)                Console.WriteLine(str);
            Console.ReadLine();
        }
    }
}
```
