Introduction

This is one of the social media implementations. Here we are fetching all the videos from a particular YouTube channel and showing in a console application
Description
We need to follow the following steps for implementing this application.
Step-1(Create an API Key)
Now before moving forward we should have a Google Developer account (e.g. any Google account).
Visit this URL. And it will come up like the following image.
create project
Now click on Create Project giving a project name and click Create. After this do as per the following image and follow the instructions.
After completing this a popup window will come and then click the Browser key. Now give a name and click Create. After this, you will get your API key by which you are going to get all the videos from a particular YouTube channel.
Step-2(Get Channel Name)
While fetching all the details of a particular channel we need to know the Channel Name.
See I am a die heart fan of Mumbai-Indians. Go to YouTube.com search Mumbai Indians as in the following image:
Youtube
You can see the 1st one is the channel as it has been written. Click on it you will get a URL as https://www.youtube.com/user/mipaltan.
Here mipaltan is the channel name. You can take any of your preferred channel names in this process.
Step-3(Programming)
Create a console application using visual studio.
Search and Install YouTube.V3 from the Nuget Package Manager Console.
Add your code as per below
  1. class Program
  2. {
  3. static void Main(string[] args)
  4. {
  5. try
  6. {
  7. var yt = new YouTubeService(new BaseClientService.Initializer() { ApiKey = "AIzaSyCT8kXaxJ2l29vYg4HBdYy36H-PhAH-Teg" });
  8. var channelsListRequest = yt.Channels.List("contentDetails");
  9. channelsListRequest.ForUsername = "mipaltan";
  10. var channelsListResponse = channelsListRequest.Execute();
  11. int VideoCount=1;
  12. foreach (var channel in channelsListResponse.Items)
  13. {
  14. var uploadsListId = channel.ContentDetails.RelatedPlaylists.Uploads;
  15. var nextPageToken = "";
  16. while (nextPageToken != null)
  17. {
  18. var playlistItemsListRequest = yt.PlaylistItems.List("snippet");
  19. playlistItemsListRequest.PlaylistId = uploadsListId;
  20. playlistItemsListRequest.MaxResults = 50;
  21. playlistItemsListRequest.PageToken = nextPageToken;
  22. // Retrieve the list of videos uploaded to the authenticated user's channel.
  23. var playlistItemsListResponse = playlistItemsListRequest.Execute();
  24. foreach (var playlistItem in playlistItemsListResponse.Items)
  25. {
  26. Console.WriteLine("Sl No={0}", VideoCount);
  27. Console.Write("Video ID ={0} ", "https://www.youtube.com/embed/" + playlistItem.Snippet.ResourceId.VideoId);
  28. //Console.Write("Video Title ={0} ", playlistItem.Snippet.Title);
  29. //Console.Write("Video Descriptions = {0}", playlistItem.Snippet.Description);
  30. //Console.WriteLine("Video ImageUrl ={0} ", playlistItem.Snippet.Thumbnails.High.Url);
  31. //Console.WriteLine("----------------------");
  32. VideoCount++;
  33. }
  34. nextPageToken = playlistItemsListResponse.NextPageToken;
  35. }
  36. Console.ReadLine();
  37. }
  38. }
  39. catch (Exception e)
  40. {
  41. Console.WriteLine("Some exception occured" + e);
  42. }
  43. }
  44. }
