How to auto find a component inside an assembly (dll)?

I'm first downloading the assembly

     private IEnumerator DownloadScripts(){
         string url = "http://www.zzzzz.com/scripts.dll"; //here is tocame code
         WWW wwwScripts = new WWW(url);
         yield return wwwScripts;
         Assembly assem = Assembly.Load(wwwScripts.bytes);
         System.Type[] TYPES = assem.GetTypes();
     }

Then a assetbundle that contain a reference to a component (tocame):

     private IEnumerator DownloadAssetBundle(){
         WWW wwwAssetBundle;
         string url = "http://zzzz.com/Cubes.unity3d";
         wwwAssetBundle = new WWW(url);
         yield return wwwAssetBundle;
         AssetBundle bundle = wwwAssetBundle.assetBundle;
         AssetBundleRequest request = bundle.LoadAsync("MainSC",typeof(GameObject));
         yield return request;
         Instantiate(request.asset) as GameObject;
     }

How can I force to Unity to find the script dependence into my TYPES Array (see code)or any way to achieve this?

I don't want to use Assembly.GetType("Tocame") and then AddComponent because Tocame component in assetbundle has public variables set in inspector.
