ArcGIS可以发布具有编辑功能的Feature Service。利用Feature Service我们可以实现对数据的在线编辑。 数据制作参考&＃xff1a; https://server.arcgis.com/zh-cn/server/latest/get-started/windows/tutorial-set-up-feature-service-data-for-offline-use.htm

其中OutFields控制着属性的编辑&＃xff0c;*代表都可以写入&＃xff0c;也可以只填写你需要编辑的属性字段。

主要是对Featureservice的图形进行编辑。 首先从Featureservice中获取table,在table中进行一系列的操作。UpdateAsync修改的feature&＃xff0c;DeleteAsync删除&＃xff0c;AddAsync添加。最后通过SaveResult&＃xff08;&＃xff09;将编辑结果上传到服务中。
