如何解决Remoting无法传输存储过程参数的问题

   在项目的开发中使用Remoting，并且所有的数据请求服务都是通过Remoting完成的，所以自然就在其中到了传递参数的存储过程，在业务逻辑中把参数构建好后传递到Remoting服务端，在取出存储过程的参数时报错，具体错误不记得了，自己尝试了各种方法也不行，上网资讯也没有结果，最后变通了一下，问题解决了，例子如下：

以下部分为客户调用端

 1//先声明参数
 2        private const string PARAM_GUID = "@GUID";
 3        private const string PARAM_VGA_TREEGUID = "@VGATreeGUID";
 4        private const string PARAM_MB_TREEGUID = "@MBTreeGUID";
 5
 6        public static string GetProductTypeByGUID(string GUID, String VGATreeID, String MbTreeID)
 7        {
 8            try
 9            {
10                int lcID = Thread.CurrentThread.CurrentUICulture.LCID;
11
12                BaseModel bt = new BaseModel();
13
14                //构建一个哈希表，把参数依次压入
15                Hashtable parames = new Hashtable();
16                parames.Add(PARAM_PROGUID, GUID);
17                parames.Add(PARAM_VGA_TREEGUID, VGATreeID);
18                parames.Add(PARAM_MB_TREEGUID, MbTreeID);
19
20                //把存储过程名称和带参数的哈希表传入
21                DataAccess.DataBase.RunProcedureDataSet(lcID, "GetProductTypeByTreeID", parames, ref bt);
22
23                return bt.Rows[0]["ProductType"].ToString();
24            }
25            catch (Exception ex)
26            {
27                CommFunction.WriteErrorLogFile("public static string GetProductTypeByGUID(stirng GUID, String VGATreeID, String MbTreeID)出错：" + ex.Message);
28                return "Other";
29            }
30        }
31

以下为服务端：
    

 1public void Query(int lcid, string SQLString, Hashtable cmdHashtable, ref BaseModel baseModel)#region public void Query(int lcid, string SQLString, Hashtable cmdHashtable, ref BaseModel baseModel)
 2        // -----------------------------------------------------------------------------------------
 3        public void Query(int lcid, string SQLString, Hashtable cmdHashtable, ref BaseModel baseModel)
 4        {
 5            if (!CheckRemotingClient())
 6            {
 7                return;
 8            }
 9            Console.WriteLine(DateTime.Now.ToString() + "调用了Query(" + lcid.ToString() + ", string SQLString, Hashtable cmdHashtable, ref BaseModel baseModel)");
10            int i = cmdHashtable.Count;
11            //以下构造存储过程参数
12            SqlParameter[] cmdParms = new SqlParameter[i];
13            int j = 0;
14            foreach (DictionaryEntry de in cmdHashtable)
15            {
16                cmdParms[j] = new SqlParameter(de.Key.ToString(), de.Value);
17                j++;
18            }
19            Colorful.DBUtility.DbHelperSQL.Query(lcid, SQLString, cmdParms, ref  baseModel);
20        }
21        // -----------------------------------------------------------------------------------------
22        #endregion
