在專案的開發中使用Remoting，並且所有的資料請求服務都是透過Remoting完成的，所以自然就在其中到了傳遞參數的預存過程，在業務邏輯中把參數建置好後傳遞到Remoting服務端，在取出預存程序的參數時報錯，具體錯誤不記得了，自己嘗試了各種方法也不行，上網資訊也沒有結果，最後變通了一下，問題解決了，例子如下：
以下部分為客戶調用端
1//先聲明參數
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 //建構一個哈希表，把參數依序壓入
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 //把預存程序名稱和帶參數的哈希表傳入
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)出錯：" + ex.Message);
28 return "Other";
29 }
30 }
31
32
以下為服務端：
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() + "呼叫了Query(" + lcid.ToString() + ", string SQLString, Hashtable cmdHashtable, ref BaseModel baseModel)");
10 int i = cmdHashtable.Count;
11 //以下建構預存程序參數
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
