我正在尝试在ASP.net项目上使用 Oracle ODP.NET 11g（11.1.0.6.20）Instant Client 作为
数据提供程序， 但是当我运行aspx页面时，出现“ 提供程序与版本不兼容Oracle客户端 错误消息。任何帮助，将不胜感激。

我在Visual Studio 2005中引用了数据提供程序，其背后的代码如下所示：

using Oracle.DataAccess.Client;
..

OracleConnection oOracleConn = new OracleConnection();
oOracleConn.ConnectionString =
    "Data Source=MyOracleServerName;" +
    "Integrated Security=SSPI";
oOracleConn.Open();

//Do Something

oOracleConn.Close();

该页面的错误如下所示：
