Load a C++ DLL at runtime

I am using DllImport to load a C++ dll. A user uses my code by passing a string to the MyClass constructor

I want to load the specified DLL path that was provided in the MyClass constructor and then I want methods to be able to access the loaded DLL.

How do I code it so that all the user has to type is new MyClass().DoSomething()?

You need the LoadLibrary and GetProcAddress methods from Win32 and then the Marshal.GetDelegateForFunctionPointer method. For a detailed description see this msdn blog:
