使用Oracle.DataClient时,提供程序与Oracle客户端错误的版本不兼容

Question

我正在使用Visual Studio 2008 Express Edition,我正在尝试使用Oracle.DataClient开发一个小应用程序.当我尝试连接到目标系统中的数据库时,我收到了上述错误.

我已经为Oracle 10gR2添加了对Oracle ODP.net提供程序的引用,并且在目标计算机中我安装了Oracle 10gR2数据库的副本.尽管如此,我收到了错误.在发布之前,我在SO上阅读了这篇文章,并且我安装了即时客户端,错误仍然存​​在.下面是完整的错误堆栈.

我在开发应用程序的机器上安装了Oracle 11g,它在那里工作正常,但在目标机器上,我收到了这个错误.任何输入将不胜感激.

PS:如上所述,引用的Oracle.DataClient.dll文件版本对应10gR2,而不是11g.

我一直在研究这个问题,你只需要从相同的下载版本的ODP.Net中获取所有相应的DLL,并将它们放在与Exe文件相同的文件夹中,因为ODP.Net对于不混合而言非常挑剔版本号,这是你看到的问题(或者oci.dll完全缺失,在这种情况下,它会产生相同的错误).

我在这里解释了如何做到这一点:http://splinter.com.au/using-the-new-odpnet-to-access-oracle-from-c 以下是它的要点:

• 下载http://www.oracle.com/technology/software/tech/windows/odpnet/index1110710beta.html
• 解压缩文件
• 解压缩其中的所有JAR
• 抓住刚刚解压缩的这些dll:oci.dll(从'oci.dll.dbl'重命名)Oracle.DataAccess.dll oraociicus11.dll OraOps11w.dll orannzsbb11.dll oraocci11.dll ociw32.dll(从'ociw32.dll重命名. DBL")
• 将所有DLL放在与C#Executable相同的文件夹中
