    }
}

 

整个类没什么特别有技术含量的东西，

提供了3个方法

public string[] GetPageURIsByDword(string dWord, int page)

 

public Mp3Struck[] GetListByDword(string dWord, int page)

 

public Mp3Struck GetDownURI(string downURI)

 

第2方法是获取一个 MP3STRUCK的集合

MP3STRUCK是一个结构体用来保存MP3的各种信息 包括 歌手 歌名 下载地址 等等

但是由于这个方法一次要请求30多个 SOUGOU的页面 所以不推荐使用

 

第1个方法是返回歌曲下载链接的集合

 

第3个方法则可以通过返回的歌曲下载链接地址 获取MP3STRUCK

 

下面是利用片段

protected void Button1_Click(object sender, EventArgs e)
        {
            SougouMp3Search.Mp3Search cl = new Mp3Search();
            SougouMp3Search.Mp3Struck[] mp3Strucks = cl.GetListByDword(TextBox1.Text.Trim(), Convert.ToInt32(TextBox2.Text.Trim()));
            foreach (var struck in mp3Strucks)
            {
                Response.Write("歌手:" + struck.Author + "</br>");
                Response.Write("歌名:" + struck.Name + "</br>");
                Response.Write("类型:" + struck.Type + "</br>");
                Response.Write("大小:" + struck.Size + "</br>");
                int count = 1;
                foreach (var h in struck.DownloadURI)
                {
                    Response.Write("<a href=\""+h+"\">下载"+count + "</a></br>");
                    count++;
                }
                Response.Write("</br>");
            }
        }
