Assembly bedingt einbinden

[FredlFesl]

Mit Interfaces ist das aber obersimpel

Code:

public IMyInterface GetInstanceFromFile (string filename)
{
  Assembly assembly = Assembly.LoadFile(filename);
  foreach (Type type in assembly.GetTypes())
    if (type.IsClass && type.IsPublic)
      if (type.GetInterfaces().Contains(typeof(IMyInterface)))
        return (IMyInterface)Activator.CreateInstance(type);
}
