关于python调用C#库的问题 5C

 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"?

 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?

以下是用makepy转化C# COM生成的.py:
