.net dllimport DllNotFoundException但dll确实存在。

Question

I'm using DllImport in my c# application. It works fine on my windows 7 machine, but on a windows 8 it gives the DllNotFoundException.

A customer of our has the same issue on his windows 7 machine.

I even hacked the code just to test it out by supplying the absolute path like so

[DllImport("C:\\Program Files (x86)\\MyApp\\A.dll", CallingConvention = CallingConvention.Cdecl)]
private static extern void foo(string filename, MulticastDelegate callback);

But it still gives the DllNotFoundException at the path C:\\Program Files (x86)\\MyApp\\A.dll ....

But the DLL is indeed there!!! ....

Answer 1

路径有空格，所以我的猜测是使用：

[DllImport("\"C:\\Program Files (x86)\\MyApp\\A.dll\"", ...]
