ArcGIS Pro批量加字段测试代码，很慢

  private async void BatchAddField()
        {
            MapView mapView = MapView.Active;
            if (mapView == null)
            {
                return;

            }
            FeatureLayer featureLayer = mapView.Map.Layers[0] as FeatureLayer;
            System.Diagnostics.Stopwatch MyWatch = new System.Diagnostics.Stopwatch();

            MyWatch.Start();
            for (int i = 0; i < 10; i++)
            {
                await YLPub.YLProPub.AddField(featureLayer, "A" + i.ToString(), "Long", 20);


            }
            MyWatch.Stop();

            MessageBox.Show("删除时间:" + MyWatch.ElapsedMilliseconds.ToString() + "毫秒");
            //featureLayer.GetFeatureClass().GetDatastore().
        }
