推荐答案

不，不是真的 - 这不是一个问题，它是一个教程！我们不能在这样的小文本框中给出复杂主题的教程 - 这绝对是 -



从MSDN开始：使用P / Invoke调用托管类中的非托管API [ ^ ]并查看如果这有帮助。

No, not really - that isn't a question, it's a tutorial! And we can't give tutorials on complex subjects - which this most definitely is - in a little text box like this...

So start with MSDN: Using P/Invoke to Call Unmanaged APIs from Your Managed Classes[^] and see if that helps.
