The **Intersect** method or operator is used to combine multiple collections or lists into a single collection or list and return common elements from both collections.

## Syntax

```
var result = collection.Intersect(collection2);
```

## Example

```
using System;using System.Collections.Generic;using System.Linq;
public class Program{ public static void Main() {  List<string> count1= new List<string>() { 'UK', 'Australia', 'India', 'USA' };  List<string> count2 = new List<string>() { 'India', 'UAE', 'Canada', 'UK', 'China', 'Pok' };
  List<string> list = count1.Intersect(count2).ToList();  list.ForEach( country => Console.WriteLine(country) );
  Console.ReadLine(); }}
```

## Output

```
UK
India
```
