在Python 中調用Dll

1.首先寫DLL文件，環境是在VC 6.0中

如下所示：

1. // funDll.cpp : Defines the entry point for the DLL application.
2. //
4. #include "stdafx.h"
5. #include <iostream>
6. using namespace std;
8. #ifdef _MANAGED
9. #pragma managed(push, off)
10. #endif
12. #ifdef __cplusplus
13. #define EXPORT extern "C"__declspec(dllexport)
14. #else
15. #define EXPORT __declspec(dllexport)
16. #endif
17. EXPORT int HelloWorld()
18. {
19. cout <<"hello world" <<endl;
20. return 0;
21. }
24. BOOL APIENTRY DllMain( HMODULE hModule,
25. DWORD ul_reason_for_call,
26. LPVOID lpReserved
27. )
28. {
29. return TRUE;
30. }
32. #ifdef _MANAGED
33. #pragma managed(pop)
34. #endif

2.然後書寫python調用DLL代碼。

1. #coding=utf-8
2. '''''

6. '''
7. from ctypes import *
8. fileName = "funDll.dll"
9. func = cdll.LoadLibrary(fileName)
10. #print func.HelloWorld()ffd天下第一
14. func.HelloWorld()

如果出現"Hello world"，說明運行成功。
