use unknown dll

[Eric]

Hi, I wonder if it is possible to import and use an unknown dll in a C#
program? I.e. get to know what public variables, methods, properties
etc. the dll contains and get to know what parameters to call the
methods with, what the properties return etc. Does it have to be a .net
dll?

Thanks!

Eric,

Well, you can use reflection for .NET dlls, but this isn't the
recommended way to handle unknown dlls. Typically, you will want types in
dlls (in a known location) to implement an interface, then create instances
of those types and cast to the interface.

Hope this helps.

It's a .net it's much easier , you can use reflection to know about all the
types the dll defines.

What are you trying to do?

Are you trying to implement plug ins ?

I'm affraid he's talking about non .NET DLL's, notice it's last sentence...
"Does it have to be a .net dll?"
