I have a assembly. In this assembly I have a class and interface. I need to load this assembly at runtime and want to create an object of the class and also want to use the interface.

Assembly MyDALL = Assembly.Load("DALL"); // DALL is name of my dll
Type MyLoadClass = MyDALL.GetType("DALL.LoadClass"); // LoadClass is my class
object obj = Activator.CreateInstance(MyLoadClass);

This is my code. How could it be improved?

If your assembly is in GAC or bin use the assembly name at the end of type name instead of Assembly.Load().

object obj = Activator.CreateInstance(Type.GetType("DALL.LoadClass, DALL", true));
