Question

我有一个谜题。有时我们的程序出现“未指定'xxx.DataAccess.UDT_Table_Numbers'的自定义类型映射或无效。”例外。我重新启动IIS服务器后，它是工作。任何帮助将不胜感激。

关系代码如下：

                                            List<string> LstPrice)

        OracleConnection conn = new OracleConnection(OracleHelper.Wistron_WOMS_ConnStr);
        OracleCommand cmd = new OracleCommand();

        try
        {
            ....

            OracleParameter[] parmArray = {

            parmArray[7].Size = 5000;   

            parmArray[0].Direction = ParameterDirection.Input;
            parmArray[1].Direction = ParameterDirection.Input;
            parmArray[2].Direction = ParameterDirection.Input;

            foreach (OracleParameter parm in parmArray)
            {
