Answer 1

In case you are writing some application with view model (e.g. ASP.NET MVC):

public string YouTubeUrl { get; set; }

public string YouTubeVideoId
{
    get
    {
        var youtubeMatch =
            new Regex(@"youtu(?:\.be|be\.com)/(?:.*v(?:/|=)|(?:.*/)?)([a-zA-Z0-9-_]+)")
            .Match(this.YouTubeUrl);
        return youtubeMatch.Success ? youtubeMatch.Groups[1].Value : string.Empty;
    }
}
