我注意到它说我有一个无效的连接字符串，但我测试了它，它的工作原理。我目前安装了Oracle 10g Express，之前我使用的是Oracle 8i Client。在我安装10g Express之前它正在工作。

Answer 1

我遇到了与oracle 10g相同的问题，从我所看到的这个错误似乎意味着.Net oracle驱动程序找不到oracle客户端。

有许多建议可以解决这个问题，包括检查PATH和ORACLE_HOME环境变量;在默认位置（C：\ oracle）重新安装oracle客户端（如果它尚不存在）;或者使用oracle的Oracle Data Provider for .NET（ODP.NET）而不是Microsoft oracle驱动程序（System.Data.OracleClient）。

上述情况都没有解决我的问题，所以如果有人有任何建议，我们将非常欢迎！

Answer 2

我们最近也遇到过这种情况;在我们的例子中，恢复ORACLE_HOME环境变量就行了（OMS10G的不完整安装使系统处于不一致状态，环境变量注册为null）。

Answer 3

我在Windows 7机器上遇到过这种情况。在“windows xp sp3”兼容模式（文件/属性/兼容性）中添加ORACLE_HOME环境变量并运行使用oracle客户端的可执行文件为我解决了这个问题。

Answer 4

虽然这个问题有点古老，但我会投入五美分。从我在互联网上阅读的内容来看，即使在调用者（用户登录到Windows）无权读取/执行Oracle二进制文件时一直配置的环境中也会出现这种情况。

Answer 5

从中删除System.Data.OracleClient.dll \Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5

请确保在出现任何其他错误时先备份

这对我有用。

或从以下文件夹中替换System.Data.OracleClient.dll Windows\Microsoft.NET\assembly\GAC_32\System.Data.OracleClient\v4.0_4.0.0.0__b77a5c561934e089
