No of Subscribers per Video

To get the number of subscribers, you need to use the channels endpoint of the YouTube Data API. The statistics part of the response will contain the subscriber count. Here’s how you can modify your code:

var client = new RestClient("https://www.googleapis.com/youtube/v3");
var request = new RestRequest("channels", Method.GET);
request.AddParameter("part", "snippet,statistics");
request.AddParameter("id", "UCg3ZngG-m_nNoVw");
request.AddParameter("key", "AIzaSyYUSl87HSSG9b5Ls8ECKH8");

IRestResponse response = client.Execute(request);

if (response.Data != null && response.Data.Items != null && response.Data.Items.Count > 0)
{
    var channel = response.Data.Items[0];
    Console.WriteLine($"Channel Title: {channel.Snippet.Title}");
    Console.WriteLine($"Subscriber Count: {channel.Statistics.SubscriberCount}");
}

 

In this code, YoutubeChannelResponse is a class that you would need to define to deserialize the response from the YouTube Data API. It should include properties that match the structure of the API response.

Please note that the subscriber count will only be visible if the channel has chosen to make this information public. If the channel has chosen to hide their subscriber count, this field will not be present in the API response. Also, please ensure that you have the necessary permissions and quota to make these API requests. You might need to handle API quota limits and pagination for large result sets.

Remember to replace "UCg3ZngG-m_nNoVw" and "AIzaSyYUSl87HSSG9b5Ls8ECKH8" with your actual channel ID and API key. Be careful not to share your API key publicly. It’s a sensitive piece of information that can be used to access and modify your YouTube Data.

To retrieve the number of subscribers along with the video details, you'll need to make an additional request to the YouTube Data API to fetch information about the channel. Below is an example of how you can modify your existing code to achieve this:

 

var client = new RestClient("https://www.googleapis.com/youtube/v3");
var videoRequest = new RestRequest("search", Method.GET);
videoRequest.AddParameter("part", "snippet");
videoRequest.AddParameter("type", "video");
videoRequest.AddParameter("maxResults", 400);
videoRequest.AddParameter("channelId", "UCg3ZngG-m_nNoVw");
videoRequest.AddParameter("key", "YOUR_API_KEY");

// Execute request to get video details
IRestResponse videoResponse = client.Execute(videoRequest);

if (videoResponse.IsSuccessful)
{
    // Extract video details
    List videoItems = videoResponse.Data.Items;

    foreach (var videoItem in videoItems)
    {
        string videoId = videoItem.Id.VideoId;

        // Now make another request to get channel statistics
        var channelRequest = new RestRequest("channels", Method.GET);
        channelRequest.AddParameter("part", "statistics");
        channelRequest.AddParameter("id", "UCg3ZngG-m_nNoVw");
        channelRequest.AddParameter("key", "YOUR_API_KEY");

        IRestResponse channelResponse = client.Execute(channelRequest);

        if (channelResponse.IsSuccessful)
        {
            // Extract subscriber count from channel statistics
            int subscriberCount = int.Parse(channelResponse.Data.Items[0].Statistics.SubscriberCount);

            // Now you can use both videoItem and subscriberCount as needed
            Console.WriteLine($"Video Title: {videoItem.Snippet.Title}");
            Console.WriteLine($"Video ID: {videoId}");
            Console.WriteLine($"Subscriber Count: {subscriberCount}");
            Console.WriteLine();
        }
        else
        {
            Console.WriteLine($"Error retrieving channel statistics: {channelResponse.ErrorMessage}");
        }
    }
}
else
{
    Console.WriteLine($"Error retrieving video details: {videoResponse.ErrorMessage}");
}

This code first retrieves video details using the provided channelId, then for each video, it fetches the subscriber count for the corresponding channel using the same channelId. Make sure to replace "YOUR_API_KEY" with your actual YouTube Data API key. Additionally, handle error cases appropriately in your actual application.
