skyline开发——加载Shapefile文件

 //1）获取道路的GroupID
                string dlId = ptm.FindGroupByName("道路");
                IFeatureLayer66 featureLayer = null;
                string tShapeFileName = path + "out_feature_class.shp";
                string tConnectionString = String.Format("FileName={0};TEPlugName=OGR;", tShapeFileName);
                featureLayer = sgworld.Creator.CreateFeatureLayer("clip_result", tConnectionString, dlId);
                //featureLayer.DataSourceInfo.ConnectionString = path + "out_feature_class.shp";

                featureLayer.FeatureGroups.Polyline.SetProperty("Line Color", 16776960);
                featureLayer.FeatureGroups.Polyline.SetProperty("Line Width", 10);

                var featureLayerDataSource = featureLayer.DataSourceInfo;
                //var cAttributes = cFeatureLayerDataSource.Attributes;
                featureLayerDataSource.Attributes.ImportAll = true;

                featureLayer.Streaming = false;
                featureLayer.Load();


                //2) 定位到道路
                var cFlyToPos = featureLayer.Position.Copy();
                cFlyToPos.Pitch = -89.0; // Set camera to look downward on polygon
                //cFlyToPos.X = 10.50;
                //cFlyToPos.Y = 47.50;
                cFlyToPos.Distance = 3500;
                sgworld.Navigate.FlyTo(cFlyToPos, ActionCode.AC_FLYTO);
