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
32

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
