I have find the solution for download you tube videos using c# code.

First need install the "libvideo" on NuGet package manager console in visual studio.

Here Fire this command on package manger console :

Install-Package VideoLibrary

First add this namespace on top in your controller :

using VideoLibrary;

Now here just write just code and pass the url link :

var VedioUrl = "https://www.youtube.com/embed/" + objYouTube.VideoID + ".mp4";
var youTube = YouTube.Default;
var video = youTube.GetVideo(VedioUrl);
System.IO.File.WriteAllBytes(Server.MapPath("~/youtube/" + video.FullName + ".mp4"), video.GetBytes());

You can embed youtube-dl in your app.
It provides extensive Youtube download options.

Basically, you do something like this.

using System;
using System.Diagnostics;
using System.ComponentModel;

namespace MyProcessSample
{
    class MyProcess
    {
        public static void Main()
        {
            Process myProcess = new Process();

            try
            {
                myProcess.StartInfo.UseShellExecute = false;
                myProcess.StartInfo.FileName = @"yourpath\youtube-dl.exe";
                myProcess.StartInfo.CreateNoWindow = false;
                myProcess.StartInfo.Arguments = "https://www.youtube.com/watch?v=KFqrp4KSxio";
                myProcess.Start();
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
            }
        }
    }
}

You can use this C# wapper for youtube-dl.
You can extend it to suite your needs.
