How would i export object to Qml by SetContextProperty ?

[jaredtao]

question

I want to export object to Qml by SetContextProperty, but qml report error on console:

   xxx.qml:  TypeError: Cannot read property 'transString' of null

detail

I have a class declare like this:

 public class Trans 
 {
        [NotifySignal("currentLangChanged")]
        public string currentLang { get; set; } = "English";

        [NotifySignal("transStringChanged")]
        public string transString { get; set; } = "";

        [NotifySignal("languagesChanged")]
        public List<string> languages { get; set; }
        
        ....

        public void loadFolder(string folder) 
        {  ....   }
 }

I want to call loadFolder in c# not qml, so i use SetContextProperty in main function

        static int Main(string[] args)
        {
             ...
             var trans = new Trans();
             trans.loadFolder(Config.Config.transPath);
             engine.SetContextProperty("trans", trans);
             .....
        }
