DllImport vs LoadLibrary, What is the best way?

Question

i'm usually using Win32 API in c#.NET. But not declare all in one application. Sometimes usually using user32, sometimes gdi32 ... I think when i declare all api function, those use lot of memory. What is the best way using API in .NET ?

Answer 1

LoadLibrary is useful when you are writing code that might be used in an environment that may or may not have the desired dll -- for example, you might have a program that can use a special crypto dll if it is available, but can still operate without it. Using DllImport would require that dll to exist.
