            request.AddParameter("part", "snippet");

                foreach (var searchResult in tagResponse0.Data.items)
                {
                    listVideo.Add(searchResult);
                    var tags = searchResult.snippet.tags;
                }
            }

To extract search keywords from a video using the given code, you need to access the tags property within the snippet of each video item. The tags property contains the keywords associated with the video. By iterating through the items in the response and accessing the snippet.tags property, you can retrieve the search keywords.

Here is a snippet of how you can access the search keywords from the video data:

foreach (var searchResult in tagResponse0.Data.items)
{
    listVideo.Add(searchResult);
    var tags = searchResult.snippet.tags;
    // 'tags' variable now contains the search keywords for the current video
}
