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 == 0)
        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(0, tmp.Length - 1) + ")");
        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() == "" ? "0" : reader["CountSum"].ToString());
            strSql.AppendFormat("F_HLJE = {0} * (isnull(F_HTDJ,F_BGHDJ)) ", reader["CountSum"].ToString() == "" ? "0" : 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 > 0)

            return "保存成功！";

        else
            return "保存失败！";
    }
}
