我想建立一个DLL类库使用COM互操作，用C＃，针对任何CPU，并将其注册为32位和64位接口。

I want to build a DLL Class Library use COM Interop, with C#, target ANY CPU, and register it as 32-bit and 64-bit interfaces.

我希望能够在运行时，显示的内容界面使用 - 如果我现在用的是32位版本或64位版本的

I want to be able to, at runtime, display what interface was used - if I am using the 32-bit version, or 64-bit version.

任何想法？

推荐答案

为了让一个进程加载32位的DLL，该过程必须是32位。而同样为64位。因此，要找出已经被加载，假设它已经工作，你只需要找出位岬的CLR的：

In order for a process to load a 32-bit DLL, the process has to be 32-bit. And same for 64-bit. So to find out what has been loaded, assuming it has already worked, you just need to find out the bit-ness of the CLR:

if (System.IntPtr.Size == 8)
{
    // 64-bit
}
else
{
    // 32-bit
}
