在我做任何评论之前，我想请你提供一些关于你想要实现的目标？的描述。 br />


因为，如果要将值分配给来自不同类型的任何变量，那么有时不使用类型转换或转换，简单的内存副本也可以这样做。 / blockquote>

我使用 GetIUknownForObject解决了这个问题 [ ^ ]然后 GetObjectForIUknown [ ^ ]。

Good luck!

Before I made any comment, I would rather like to ask you to provide a bit description about - "What you are trying to achieve?"

Because, if you want to assign value into any variable from a different type, then sometime with out type casting or converting, a simple memory copy can do the same.

I solved this by using GetIUknownForObject[^] and then GetObjectForIUknown[^].
