问题描述
- 关于python调用C#库的问题
-
大家好，我需要用python来调用C#的.dll，一直在研究http://blog.csdn.net/xugangjava/article/details/7202356这篇文章，现在碰到了一个问题，请大家帮忙出出主意，谢谢。首先是这篇文章中的最末尾，命令行中有一条“d.EncryptMd5('dsaf')”（如图1）。请问这个"d."是从何而来？之前也没有看到任何类例化成了"d"？
图1：
其次是我在调用由C# COM生成的.py文件中的方法时，出现了“CoClassBaseClass”类能正常例化，而“DispatchBaseClass”无法正常例化的情况（如图2和图3），请问这是为什么？如何才是正确的调用方法？

图3：
以下是用makepy转化C# COM生成的.py：
