C# - Example of LINQ Intersect() Method with OrderBy() Method

Learn about the example of Linq Intersect() method with OrderBy() method and its C# implementation. By Nidhi Last updated : April 01, 2023

Here we will create two lists of integers, then find common items using Intersect() method and then sort integer numbers using OrderBy() method and then print them on the console screen.

C# program to demonstrate the example of LINQ Intersect() method with OrderBy() method

The source code to demonstrate Linq Intersect() method with OrderBy() using Linq, is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

//C# Program to demonstrate Linq Intersect() method 
//with OrderBy() method.

using System;
using System.Linq;
using System.Collections.Generic;

class Demo
{
    static void Main(string[] args)
    {
        List<int> List1 = new List<int>() { 10, 40, 30, 20, 90 };
        List<int> List2 = new List<int>() { 10, 20, 30, 40, 50 };

        var result = List1.Intersect(List2).OrderBy(lst => lst);

        foreach (var value in result)
        {
            Console.WriteLine(value + " ");
        }
    }
}

Output

10
20
30
40

Explanation

In the above program, we created a class Demo that contains the Main() method. In the Main() method we created two lists of integers.

var result = List1.Intersect(List2).OrderBy(lst => lst);

In the above code, we find common items from both lists using the Intersect() method and then sort them using OrderBy() method.

foreach (var value in result)
{
    Console.WriteLine(value + " ");
}

In the above code, we accessed the filtered values one by one and print it on the console screen.
