有一篇来自作者的帖子＆＃34; blatt＆＃34;在互联网博客上关于它： http://cerjam.net/showthread.php?t=14410  我只是复制下面的代码

 public enum dailyQuality
    {
        ld, sd, hd, hd720
    }

    public string dailyDownload(string code, dailyQuality quality)
    {
        WebClient aclient = new WebClient();
        string pgdata = aclient.DownloadString("http://www.dailymotion.com/video/" + code);

        string video = null;

        switch (quality)
        {
            case dailyQuality.ld:
                video = Regex.Split(pgdata, "ldURL%22%3A%22")[1];
                break;
            case dailyQuality.sd:
                video = Regex.Split(pgdata, "sdURL%22%3A%22")[1];
                break;
            case dailyQuality.hd:
                video = Regex.Split(pgdata, "hdURL%22%3A%22")[1];
                break;
            case dailyQuality.hd720:
                video = Regex.Split(pgdata, "hd720URL%22%3A%22")[1];
                break;
            default:
                return "...";
        }

        video = Regex.Split(video, "%22%2C%22")[0];

        return makeNormalDaily(video);
    }

    private string makeNormalDaily(string data)
    {
        string astring = data.Replace("%3A", ":");
        astring = astring.Replace("%5C%2F", "/");
        astring = astring.Replace("%3F", "?");
        astring = astring.Replace("%3D", "=");
        return astring;
    }
