How can I export class methods from dll?

Question

C++ / C#

Several class methods are declared as _declspec(dllexport) int __cdecl SomeFunction();
The class resides in the library and is created when it is loaded into memory. Destroyed as soon as the library is unloaded from memory (respectively).
How can I get the addresses of these methods so that I can work with them after the library has been successfully loaded?
Explicit binding is used.

Answer 1

Apparently using GetProcAddress().
