Extract the video ID from youtube url in .net

Extract the video ID from youtube url in .net

To extract the video ID from a YouTube URL in .NET, you can use regular expressions to parse the URL and extract the ID.

Here is an example of how to extract the video ID from a YouTube URL in .NET:

using System.Text.RegularExpressions; public static string GetYouTubeVideoId(string url) { string videoId = null; // Regular expression pattern to match YouTube URLs string pattern = @"^(?:https?:\/\/)?(?:www\.)?(?:youtube\.com|youtu\.be)\/(?:watch\?v=)?([a-zA-Z0-9_-]+)"; // Attempt to match the URL with the pattern Match match = Regex.Match(url, pattern, RegexOptions.IgnoreCase); // If the URL matches the pattern, extract the video ID if (match.Success) { videoId = match.Groups[1].Value; } return videoId; }

In this example, we define a GetYouTubeVideoId method that takes a YouTube URL as input and returns the video ID as a string. The method uses a regular expression pattern to match YouTube URLs, and then extracts the video ID from the matched string.

The regular expression pattern matches the following formats of YouTube URLs:

  • https://www.youtube.com/watch?v=<videoId>
  • https://youtu.be/<videoId>
  • https://www.youtube.com/<videoId>
  • https://www.youtube.com/embed/<videoId>

If the URL matches one of these formats, the method extracts the video ID from the URL and returns it as a string. If the URL does not match any of these formats, the method returns null.

Here's an example of how to use the GetYouTubeVideoId method:

string url = "https://www.youtube.com/watch?v=dQw4w9WgXcQ"; string videoId = GetYouTubeVideoId(url); Console.WriteLine(videoId); // Output: dQw4w9WgXcQ
