无法使用ADO.Net连接到远程Oracle服务器连接字符串错误？

Question

我一直在尝试使用以下连接字符串连接到Oracle服务器：

            OracleConnection conn = new OracleConnection();
            conn.ConnectionString = @"Data Source=
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.206.0.23)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SID = ORCLWEX3)
    )
 )
;User Id= RAMNIVAS_CI;Password= RAMNIVAS_CI;Persist Security Info=True;";
            conn.Open();

但是收到以下错误：

System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.

虽然我已经安装了它。

我已经能够使用Oracle Sql Developer连接到该服务器。设置如下：
TNSNAMES文件是这样的：

# tnsnames.ora Network Configuration File: F:\app1\product\11.1.0\db_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

ORCLWEX1 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = oracle-db.newvisionsoftware.com)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SID = ORCLWEX1)
    )
  )

ORCLWEX2 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = oracle-db2.newvisionsoftware.com)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SID = ORCLWEX2)
    )
  )

ORCLWEX3 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.206.0.23)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SID = ORCLWEX3)
    )
  )

我被告知要使用最后一个：ORACLEWEX3 我知道连接字符串中存在一些问题，如果有人能帮助我，我将不胜感激。

如果您使用的是用户名/密码，我认为您不需要使用“持久安全信息”。看一眼： http://connectionstrings.com/oracle 更多例子。

此外，您可以尝试使用Oracle自己的.net提供程序： http://www.oracle.com/technetwork/topics/dotnet/index-085163.html 看看这对你有用。
