oledb连接oracle错误

Question

错误提示 多步 OLE DB 操作产生错误。如果可能，请检查每个 OLE DB 状态值。没有工作被完成。        OleDbConnection ConnObj = null;
        string _conn="Provider=MSDAORA.1;Password=123;User ID=oral;Data Source=\"(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.1)(PORT = 1521)))(CONNECT_DATA =(SERVICE_NAME = orcl)))\";"
        public bool JudgeConn()
         {
             if (!_conn.Contains("Connect Timeout"))
             {
                 _conn += "Connect Timeout=5;";
             }
             ConnObj = new OleDbConnection(_conn);
             try
             {
                 
                 ConnObj.Open();
                 ConnObj.Close();
                 return true;
             }
             catch (Exception ex)
             {
                 return false;
             }
         }连接字符串是正确的.这是oledb自动生成的,这在odbc数据源里就能正常连接.

 try
             {
                 
                 ConnObj.Open();
                 ConnObj.Close();
                 return true;
             }
             catch (Exception ex)
             {
                 return false;
             }
