Hello TaeYoung,


Thanks for your post, S57FeatureLayer is working good at demo version too, what's the problem are you met?


Here I can show you some sample code to use it, also please remember you need to refer the FdoExtention.dll into your projet.



S57FeatureLayer worldLayer = new S57FeatureLayer(@"D:\MapData\OneDay_ENCs\ENC_ROOT\US2EC03M\US2EC03M.000", null, "OGRSchema", "Point");
worldLayer.ZoomLevelSet.ZoomLevel01.DefaultAreaStyle = AreaStyles.Country1;
worldLayer.ZoomLevelSet.ZoomLevel01.DefaultPointStyle = PointStyles.City1;
worldLayer.ZoomLevelSet.ZoomLevel01.ApplyUntilZoomLevel = ApplyUntilZoomLevel.Level20;

worldLayer.Open();
Map1.CurrentExtent = worldLayer.GetBoundingBox();
// Here you can get all features with their column values.
Collection<Feature> features = worldLayer.QueryTools.GetAllFeatures(ReturningColumnsType.AllColumns);
worldLayer.Close();

LayerOverlay layerOverlay = new LayerOverlay();
layerOverlay.Layers.Add(worldLayer);
Map1.Overlays.Add(layerOverlay);

Map1.Refresh();

Regards,


Gary
