Creating a generic object based on a Type variable [duplicate]

Question

I need to create a generic object based on a type that is stored in a database. How can I acheive this? The code below (which won't compile) explains what I mean:

string typeString = GetTypeFromDatabase(key); Type objectType = Type.GetType(typeString);  //This won't work, but you get the idea! MyObject<objectType> myobject = new MyObject<objectType>(); 

Is it possible to do this kind of thing?

Thanks

Type type = typeof(MyObject<>).MakeGenericType(objectType); object myObject = Activator.CreateInstance(type); 

Also - watch out; Type.GetType(string) only checks the executing assembly and a few system assemblies; it doesn't scan everything. If you use an assembly-qualified-name you should be fine - otherwise you may need to get the Assembly first, and use someAssembly.GetType(string).
