Python LoadLibrary找不到

Question

我想從Python加載.dll。我在Visual Studio 2017 Preview中使用Python 3.0.17114.1。我收到一個錯誤，說「NameError：名稱LoadLibrary未定義」。

下面是一個代碼剪斷（注意theDll出來完美）：

import ctypes 
from ctypes.util import find_library 
from ctypes import LibraryLoader 
from ctypes.util import find_library  
theDll = find_library('DsiLibrary_dll') 
dsi_lib = LoadLibrary(theDll) 

所以我在調用LoadLibrary念起來有幾個不同的方式來做到這一點。我嘗試了所有我能找到的：

cdll.LoadLibrary(theDll) 
CDLL.LoadLibrary(theDll) 
ctypes.CDLL.LoadLibrary(theDll) 
ctypes.LoadLibrary(theDll) 

我對Python很新，所以我可能犯了一些愚蠢的錯誤。有人可以提出建議嗎？

您可以訪問LoadLibrary這樣的：

import ctypes 
from ctypes import cdll 
from ctypes.util import find_library  
theDll = find_library('DsiLibrary_dll') 
lib = cdll.LoadLibrary(theDll) 
# do stuff with lib 

Ctypes documentation：

On Linux, it is required to specify the filename including the extension to load a library, so attribute access can not be used to load libraries. Either the LoadLibrary() method of the dll loaders should be used, or you should load the library by creating an instance of CDLL by calling the constructor:

>>> from ctypes import * 
>>> cdll.LoadLibrary("libc.so.6") 
<CDLL 'libc.so.6', handle ... at ...> 
>>> libc = CDLL("libc.so.6")  
>>> libc 
<CDLL 'libc.so.6', handle ... at ...> 
>>>
