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

                 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 = ;
                 sgworld.Navigate.FlyTo(cFlyToPos, ActionCode.AC_FLYTO);
