ArcGIS Pro二次开发-获得一个要素的字段

var featLayer = MapView.Active.GetSelectedLayers().First() as FeatureLayer;
            QueuedTask.Run(() =>
            {
                List<FieldDescription> pFieldList = featLayer.GetFieldDescriptions();
                foreach (FieldDescription pField in pFieldList)
                {
                    MessageBox.Show(pField.Name);
                }
            });
