利用WebClient获取远程数据（仅做备份）

public DataSet GetData(string httpUrl)
              {
                     string xmlPath = @"http地址"; // 该地址不能包含中文
                     DataSet ds = new DataSet();
                     WebClient wc = new WebClient();
                     byte[] bt = wc.DownloadData(xmlPath); 
                     XmlDocument xd = new XmlDocument(); 字串2

                     string source = Byte2String(bt);

字串3

                     xd.LoadXml(source); 字串3

                     XmlNodeReader xnr = new XmlNodeReader(xd);

字串4

                     ds.ReadXml(xnr);

 

                     DataTable dt = ds.Tables[0]; 字串7

 

字串8

                     this.DataGrid1.DataSource = ds;

                     this.DataGrid1.DataBind();
   字串8

                     return ds;   字串5

              } 字串7

  字串1

              public static string Byte2String(byte[] bt) 字串6

              { 字串9

                     System.Text.Encoding encoding = System.Text.Encoding.GetEncoding("gb2312");

字串4

                     string str = encoding.GetString(bt); 字串7

                     return str; 字串6

              }
