Hi experts

I know that i can use DllImport for unmanaged dlls

C#

[DllImport("SomeFile.dll", EntryPoint="SomeFunction", SetLastError=true)]

But I got a DLL file which I don't know it's functions names.

Is there any way to find the functions of an unmanaged DLL file? like iterating or something? and how?

What I have tried:

I've been googling the issue and I haven't found anything useful so far.

You can find the names by using one of the many tools available from the internet such as Dependency Walker (depends.exe) Home Page[^]. However, you will most likely find that you need more information in order to use these functions.

5ed. Unknown signatures of those functions will still present a problem; name mangling, if it was used, can give some help, but not in all cases. So, you are right about "you need more information".

Isn't that what I said in my reply?

Let me see... Almost. You did not say what is that "more information", but I agree if you say that it's pretty obvious. Was my word "but" wrong? Well, I'll remove it.
