Are you just talking about being able to load a DLL or instantiate a class via Reflection? If so, it's easy:

string DLLName = "MyDLL.dll";
string ClassName = "MyDll.MyClass";
System.Reflection.Assembly oDLL;
object oClass;

// This "loads" the .DLL
oDLL = System.Reflection.Assembly.LoadFrom(DLLName);

// This creates the class instance
oClass = oDLL.CreateInstance(ClassName, true);

And if you need to pass parameters

// Create an object array to pass your parameters
object [] args = new object[1];
args[0] = MyKey;
oForm = (Form)oDLL.CreateInstance(classname, true, System.Reflection.BindingFlags.CreateInstance, null, args, null, null);
