给定一个非DotNET来自某个未知地方的dll
我如何知道其中的类，或者如何查看类，方法，
属性等。

简答：你不是。


更长的答案：


你可以检查DLL输出的内容（使用MS工具） ）使用此命令


dumpbin / exports randomDLL.dll


它为您提供按名称导出的函数的公共名称。 br />
可以导出无名称的函数。并非需要导出类中的所有成员函数

。

在许多（所有？）情况下，事实证明C ++成员函数的名称是

由编译器修饰（包含）有关

参数的数量和类型以及返回值的信息。但是，C ++编译器

不要使用相同的装饰方案。所以，如果您知道用于生成目标代码的编译器，您可以收集一些信息，但不是很多。


问候。

感谢Will

我会尝试它

我试过使用dumpbin，我得到以下所有


C：\ Temp> dumpbin / exports" ; C：\Program Files\SOYO\HW Monitor\itevio.dll"

（null）：错误：无法执行LINK.EXE

Hello VC,

Given a non-DotNET dll from some unknown place
How do I know the classes in it, or how do I view the classes, methods,
properties etc..

Thank you

Given a non-DotNET dll from some unknown place
How do I know the classes in it, or how do I view the classes, methods,
properties etc..

Short answer: you don''t.

Longer answer:

You can inspect what a DLL exports (using the MS tools) with this command

dumpbin/exports randomDLL.dll

That gets you the public name of the functions that are exported by name.
Functions may be exported without names. Not all member functions in classes
need to be exported.

In many (all?) cases, it turns out that C++ member functions have names
which are decorated (mangled) by the compiler to include information about
the number and type of arguments and return value. However, C++ compilers
don''t use the same decoration scheme. So, if you know the compiler used to
generate the object code you may glean some information but not a lot.

Regards.
Will

Thank Will
I will try it
