- 1、如何用python调用应用程序的.dll文件
- 2、有谁知道python怎么调用c#的dll
- 3、python怎么调用dll共享库
在Python中可以方便地使用os模块运行其他的脚本或者程序，这样就可以在脚本中直接使用其他脚本，或者程序提供的功能，而不必再次编写实现该功能的代码。
为了更好地控制运行的进程，可以使用win32process模块中的函数。
如果想进一步控制进程，则可以使用ctype模块，直接调用kernel32.dll中的函数。
1、首选运行工具 makepy.py。
2、这样就可以查看 C# dll的 com导出的 py文件了。
Python编程makepy.py代码如下：
# -*- coding: mbcs -*-
# Created by makepy.py version 0.5.00

3、举例：Python调用C# dll中的 MD5加密方法。
可以的，python中一般有两种方法调用DLL中的函数。1.直接使用函数名，函数名可以用dependencywalker等工具查看。（这个工具在vc或者vs的工具包中）[python]viewplaincopyimportctypesdll=CTYPES.CDLL(“test.dll”)res=test(3,4)2.使用Ordinal，Ordinal可以用dependencywalker等工具查看。[python]viewplaincopyimportctypesdll=CTYPES.CDLL(“test.dll”)res=dll[1](3,4)
