xml传参

前端调用后端方法时要传递多个参数，在前端js中拼接xml形式的字符串：

 var args = "<?xml version='1.0' encoding='utf-8' ?>";
 args += "<Bill>";
 for (var i = 0; i < dataChange.length; i++) {
     if (dataChange[i].bghsl != undefined) {
         if (dataChange[i].gcsl != undefined)
             args += "<Item PrimaryKey = '" + data.items[i].data.gxid + "' SSBM = '" + data.items[i].data.ssbm + "' BillCode = '" + data.items[i].data.qdbh + "' ProCount = '" + dataChange[i].gcsl + "' />";
         else
             args += "<Item PrimaryKey = '" + data.items[i].data.gxid + "' SSBM = '" + data.items[i].data.ssbm + "' BillCode = '" + data.items[i].data.qdbh + "' ProCount = '" + 0 + "' />";
     }
 }
 args += "</Bill>";

后端接收参数并解析：

 protected override string UpdateProCount(string strXml)
 {
     XmlDocument doc = new XmlDocument();
     doc.LoadXml(strXml);
     XmlElement root = doc.DocumentElement;

     StringBuilder strSql = new StringBuilder();
     StringBuilder strqd = new StringBuilder();
     foreach (XmlElement item in root.ChildNodes)
     {
         strSql.AppendFormat("update T_JJJ_JGBWQDGX set F_GCSL={0},F_BGHSL = isnull(F_BGSL,0) + {0},F_BGHJE = (isnull(F_BGSL,0) + {0}) * F_BGHDJ ", item.GetAttribute("ProCount"));
         strSql.AppendFormat("where F_ID = {0};", item.GetAttribute("PrimaryKey"));
         strqd.AppendFormat("'{0}',", item.GetAttribute("BillCode"));
     }
     int resault = GSqlDataAccess.ExecuteNonQuery("default", strSql.ToString(), null);
     if (resault == )
         return "保存失败！";
     else
     {
         string fid = root.FirstChild.Attributes["PrimaryKey"].Value;
         strSql.Clear();
         string tmp = strqd.ToString();
         strSql.Append("declare @BDBH number(19,0);");
         strSql.AppendFormat("select @BDBH = F_BDBH from T_JJJ_SGGCLQDFJ where F_ID = (select F_SGGCLQDFJ_ID from T_JJJ_JGBWQDGX where F_ID = {0});", fid);
         strSql.Append("select sum(F_GCSL) as CountSum,F_QDBH,F_BDBH from T_JJJ_SGGCLQDFJ ");
         strSql.Append("inner join T_JJJ_JGBWQDGX on T_JJJ_SGGCLQDFJ.F_ID = T_JJJ_JGBWQDGX.F_SGGCLQDFJ_ID ");
         strSql.AppendFormat("where T_JJJ_SGGCLQDFJ.F_BDBH = @BDBH and F_QDBH in {0} group by F_QDBH,F_BDBH ", "(" + tmp.Substring(, tmp.Length - ) + ")");
         IDataReader reader = GSqlDataAccess.SelectReader("default", strSql.ToString(), null);
         strSql.Clear();
         while (reader.Read())
         {
             strSql.AppendFormat("update T_JJJ_SGHTGCLQD set F_HLSL = {0}, ", reader["CountSum"].ToString() == "" ? "" : reader["CountSum"].ToString());
             strSql.AppendFormat("F_HLJE = {0} * (isnull(F_HTDJ,F_BGHDJ)) ", reader["CountSum"].ToString() == "" ? "" : reader["CountSum"].ToString());
             strSql.AppendFormat("where F_CODE = '{0}' and F_SSBM = {1};", reader["F_QDBH"].ToString(), reader["F_BDBH"].ToString());
         }
         reader.Dispose();
         resault = GSqlDataAccess.ExecuteNonQuery("default", strSql.ToString(), null);
         if (resault > )

             return "保存成功！";

         else
             return "保存失败！";
     }
 }
