该错误消息表明其中一个程序集正在引用以x86为目标构建的组件。 如果您运行x64应用程序（64位），则所使用的每个程序集必须定位到AnyCPU或x64。 任何本机代码（即：一个包装的COM对象，或通过P / Invoke调用的DLL）也必须编译为64位DLL。

项目中的一个DLL，或者由项目引用，仍然是针对x86。

That error message suggests that one of the assemblies is referencing a component that was built targetting x86.  If you run an x64 application (64bit), every assembly used must be targetting either AnyCPU or x64.  Any native code (ie: a wrapped COM object, or a DLL invoked via P/Invoke) must also be compiled as a 64bit DLL.

One of the DLLs in your project, or referenced by your project, is still targetting x86.
