{
            if (null == this.myTarget)
            {
                return;
            }
            PrefabType prefabType = PrefabUtility.GetPrefabType(mCurEditScene);
            if (prefabType == PrefabType.PrefabInstance ||
                prefabType == PrefabType.DisconnectedPrefabInstance)
            {
                GameObject rootUploadGameObject = PrefabUtility.FindValidUploadPrefabInstanceRoot(mCurEditScene.gameObject);
                var prefabParent = PrefabUtility.GetPrefabParent(rootUploadGameObject);
