tnsping效果：
用SQL Plus和PL/SQL Developer能连接上
我的tnsnames.ora位置好像不对啊！D:\Oracle\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN下面只有：
tnsnames.ora在sample里面：
tnsnames.ora里没有我的数据库sid。
tnsnames.ora文件内容：
<alias>= [ (DESCRIPTION_LIST = # Optional depending on whether u have
# one or more descriptions
# If there is just one description, unnecessary ]
(DESCRIPTION=
[ (SDU=2048) ] # Optional, defaults to 2048

这要怎么办 ？
------解决方案--------------------
应该是你c#那边有问题，这个只是一个sample文件，没问题。
------解决方案--------------------
连接串写得有问题
"password=你的密码;user id=你的帐号;data source= " & Chr(34) & "(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=你服务器的ip地址)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=你数据库的oracle服务名)))" & Chr(34) & ";"
