winform音频播放器(有声小说[凡人修仙传])

该程序采用多线程的技术及DataGridView单元格扩展的技术

1.获取下载列表

        private void GetDownList()
        {
            //System.Web.HttpUtility.UrlDecode(解密
            try
            {
                List<Model.Novel> list = new List<Model.Novel>();
                WebResponse response = null;
                StreamReader reader = null;
                string Result = "";
                Uri uri = new Uri("请求的有声小说地址");

                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri.AbsoluteUri);
                request.Method = "GET";
                response = request.GetResponse();
                reader = new StreamReader(response.GetResponseStream(), Encoding.Default);
                Result = reader.ReadToEnd();
                var htmlDocument = new HtmlAgilityPack.HtmlDocument();
                htmlDocument.LoadHtml(Result);
                var html = htmlDocument.DocumentNode;
                var title = html.CssSelect("title");
                foreach (var item in title)
                {
                    //MessageBox.Show(item.InnerHtml.ToString());
                }
                int i = 0;
                int m = 1;
                var ul = html.CssSelect("ul");
                foreach (var item in ul)
                {
                    if (i == 8)
                    {
                        foreach (var item1 in item.CssSelect("li"))
                        {
                            string no = m < 10 ? "00" + m : m < 100 ? "0" + m : m.ToString();
                            Model.Novel novel = new Model.Novel();
                            novel.Title = "凡人修仙传" + no;//item1.CssSelect("a").ToArray()[0].InnerText;
                            novel.DownDesc = "我要下载";
                            novel.PlayFile = "播放";
                            novel.DownPath = "下载地址/凡人修仙传/凡人修仙传" + no + ".mp3";//item1.CssSelect("a").ToArray()[0].Attributes["href"].Value;
                            list.Add(novel);
                            m++;
                        }
                    }
                    i++;
                }
                dgvFileList.DataSource = list;
            }
            catch (Exception ex)
            {
                WriteError(ex.Message);
                Application.Exit();
            }
            
        }

　　

2.下载文件的代码

public void DownloadFile(object RowIndex)
 {
            int index = RowIndex.GetDBNULLValue(0);
            string url = dgvFileList.Rows[index].Cells["DownPath"].Value.ToString();
            string filename = lblPath.Text + "\" + dgvFileList.Rows[index].Cells["Title"].Value.ToString() + ".mp3";
            float percent = 0;
            try
            {
                System.Net.HttpWebRequest Myrq = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(url);
                System.Net.HttpWebResponse myrp = (System.Net.HttpWebResponse)Myrq.GetResponse();
                long totalBytes = myrp.ContentLength;
                System.IO.Stream st = myrp.GetResponseStream();
                System.IO.Stream so = new System.IO.FileStream(filename, System.IO.FileMode.Create);
                long totalDownloadedByte = 0;
                byte[] by = new byte[1024];
                DateTime StartTime = DateTime.Now;
                int osize = st.Read(by, 0, (int)by.Length);
                while (osize > 0)
                {
                    totalDownloadedByte = osize + totalDownloadedByte;
                    System.Windows.Forms.Application.DoEvents();
                    so.Write(by, 0, osize);
                    osize = st.Read(by, 0, (int)by.Length);

                    DateTime EndTime = DateTime.Now;
                    TimeSpan ts = EndTime.Subtract(StartTime);
                    double iSpeed = totalDownloadedByte / ts.TotalSeconds;
                    dgvFileList[3, index].Value = Model.FileOperate.GetAutoSizeString(iSpeed, 2) + "/s";

                    percent = (float)totalDownloadedByte / (float)totalBytes * 100;
                    dgvFileList[2, index].Value = percent.GetDBNULLValue(0);
                }
                dgvFileList[3, index].Value = "下载完成,耗时" + Math.Round(DateTime.Now.Subtract(StartTime).TotalSeconds, 2) + "s";
                so.Close();
                st.Close();
            }
            catch (System.Exception ex)
            {
                WriteError(ex.Message);
            }
}
