'xxx.DataAccess.UDT_Table_Numbers'的自定義類型映射未指定或無效

Question

我有一個難題。有時我們的程序發生「xxx.DataAccess.UDT_Table_Numbers的自定義類型映射未指定或無效。」例外。重新啓動IIS服務器後，這是工作。 任何幫助將不勝感激。

關係代碼如下：

              List<string> LstPrice) 
    { 
     OracleConnection conn = new OracleConnection(OracleHelper.Wistron_WOMS_ConnStr); 
     OracleCommand cmd = new OracleCommand(); 

     try 
     { 
      ....

      parmArray[5].Direction = ParameterDirection.Input; 
      parmArray[6].Direction = ParameterDirection.Input; 
      parmArray[7].Direction = ParameterDirection.Output; 

      foreach (OracleParameter parm in parmArray) 
      { 
       cmd.Parameters.Add(parm); 
      } 

      cmd.Connection = conn; 
      cmd.CommandText = ProcedureName;
