报错如图：

监听配置：
# listener.ora Network Configuration File: e:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = e:\app\Administrator\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:e:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
(SID_DESC =
(GLOBAL_DBNAME = DBDMS)
(ORACLE_HOME = e:\app\Administrator\product\11.2.0\dbhome_1)
(SID_NAME = DBDMS)
)
(SID_DESC =
(GLOBAL_DBNAME = ORCL11G)
(ORACLE_HOME = e:\app\Administrator\product\11.2.0\dbhome_1)
(SID_NAME = ORCL11G)
)
)

LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1522))
)

ADR_BASE_LISTENER = e:\app\Administrator

tns配置：
LOCALDMS =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1522))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = DBDMS)
)
)

说明：
1、用sqlplus、PL/SQL Developer工具连接DBDMS库时无ORA-12518报错信息，一切正常
2、用C#编写的工具连接DBDMS时报上图错（在其它服务器上正常，应该是我本机Oracle配置问题）

网上搜了许多，一直找不到原因，求解答，谢谢！
