参考技术A net manager重新为你的数据库配个listner吧。

像我的listner的格式为:

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = 7NQARM2O3BV7R51)(PORT = 1521))
)
)
ipc协议是不是你所需要的？7NQARM2O3BV7R51为我的计算机名，我怀疑你的listner中host用的IP需要联网情况下才能解析(而你此时仅为单机测评，无网络环境)，试着把它改为计算机名解析或设为127.0.0.1； 参考技术B 两个文件的SID和servername对不上 参考技术C net manager 设置 图形化方便

ado.net如何连接 oracle？

VS 2010 oracle11g
关键是connectionstring 的值是多少？
我连接不上啊

OracleConnection conn = new OracleConnection("DataSource=xxxxxxx;UserId=xxxxxx;Password=xxxxxxxx;");
conn.Open();
string sql = "........";
OracleCommand cmd = new OracleCommand(sql, conn);
conn.Close();
步骤就是：1.建立Oracle的连接conn，里面包含了数据库地址，用户名和密码。并打开连接
2.确定你的SQL查询语句，写在sql字符串里
3.声明OracleCommand执行变量 cmd，包含了SQL语句和连接变量conn
4. 关闭连接
连接字符串根据自己的实际情况设置 参考技术A OracleConnection conn = new OracleConnection( "Data Source=数据库名称;user=用户名;password=密码;");
conn.Open();
数据操作；
conn.Close(); 参考技术B 你用的软件还都挺先进的啊
