我正在使用Windows 10和Oracle 11g上的Visual Studio 2012中的C#项目。
为了连接我的c#项目,我必须安装Oracle Data Access Components_ODTwithODAC121024
,一切正常。
我将项目的目标.NET框架更新为3.5,现在我收到此错误:
无法加载文件或程序集“Oracle.DataAccess,Version = 2.121.2.0,Culture = neutral,PublicKeyToken = 89b483f429c47342”或其中一个依赖项。试图加载格式不正确的程序。
经过长时间的搜索和测试,我认为是由不兼容问题引起的。 我尝试通过程序和功能启用.NET Framework 3.5 - >打开或关闭Windows功能。
我尝试从
读取引用并导入Oracle.DataAccess.dllC:\应用\萨默尔\产品\ 11.2.0 \ dbhome_1 \ ODP.NET \ BIN \ 2.x的
我还使用了Oracle数据访问组件附带的Oracle.DataAccess.dll
当我禁用处理oracle命令的方法时,我的项目工作正常。

答案 0 :(得分:0)
您指的是ODP.NET版本2. 121 .2.0。但似乎您已安装Oracle客户端 11.2 。版本必须相互匹配(至少是主版本号)
打开您的* .csproj文件并设置Oracle.DataAccess的引用,如下所示:
<Reference Include="Oracle.DataAccess">
<SpecificVersion>False</SpecificVersion>
</Reference>
不需要Version=...
或processorArchitecture=...
等属性。您的应用程序将加载正确的Oracle.DataAccess.dll
,具体取决于所选的体系结构和目标.NET框架
