推荐答案

右键点击你正在使用的应用程序池，然后转到高级设置。在（一般）有一个叫启用32位应用程序设置。如果你在64位操作系统上运行，这是设置为真然后应用程序池将是一个32位的过程，因此，你的64位的DLL将不会加载。将其设置为假来使你的应用程序池一个64位的过程。

Right click on the application pool you are using and go to Advanced Settings. Under (General) there is a setting called Enable 32-Bit Applications. If you're running on a 64 bit OS and this is set to true then the app-pool will be a 32bit process, and therefore your 64bit DLL won't load. Set it to false to make your app-pool a 64bit process.

此外，还要检查你正在构建为64位的DLL的依赖关系。它可以使用一个32位的DLL /组件。如果你有任何 [的DllImport] 属性在code，那么看看它们指的是.dll文件，并确保他们是64位兼容。

Also, check the dependencies of the DLL you're building as 64bit. It may be using a 32bit dll/assembly. If you've got any [DllImport] attributes in your code then look at the .dlls they refer to and ensure they're 64bit compatible.
