c# - Xamarin Image Grid from Folder -

i trying display image grid text. using images folder. have tries various approaches , tutorials no success. have both read , write permissions internal , external storage. whenever debug application blank screen. have tried setting breakpoint on adapters getview() method never gets hit.

here mainactivity oncreate() method:

protected override void oncreate(bundle bundle) {     if (!_dir.exists()) { _dir.mkdir(); }      base.oncreate(bundle);     setcontentview(r.layout.main);      string[] filepath = null;     string[] filename = null;      if (_dir.isdirectory)     {         droidio.file[] imagelist = _dir.listfiles();         filepath = new string[imagelist.length];         filename = new string[imagelist.length];          (int = 0; < imagelist.length; i++)         {             filepath[i] = imagelist[i].absolutepath;             filename[i] = imagelist[i].name;         }     }      var gvimagelist = findviewbyid<gridview>(r.id.gvimagelist);     gvimagelist.setadapter(new imagesfromfolderadapter(this, filepath, filename));     gvimagelist.itemclick += delegate { gvimagelist_itemclick(); }; } 

and image adapter class:

public class imagesfromfolderadapter : baseadapter {     private activity context;     private string[] filepath;     private string[] filename;      public  imagesfromfolderadapter(activity c, string[] fp, string[] fn)     {         this.context = c;         this.filename = fn;         this.filepath = fp;     }      public override int count { get; }      public int getcount()     {         return filepath.length;     }      public override java.lang.object getitem(int position)     {         return position;     }      public override long getitemid(int position)     {         return position;     }      public override view getview(int position, view convertview, viewgroup parent)     {         view view = convertview;         if (view == null)             view = context.layoutinflater.inflate(r.layout.gallery_item_layout, null);          view.findviewbyid<imageview>(r.id.gitemimage).setimagebitmap(bitmapfactory.decodefile(filepath[position]));         view.findviewbyid<textview>(r.id.gitemtext).text = filename[position];          return view;      } } 

any ideas going wrong? using lg g3 debug device if helps. thankyou in advance.

you returned 0 count grid adapter.

change

public override int count { get; }

to

 public override int count  {       { return filepath.length; }  }
