C# soe二次开发创建项目，并添加到server服务上
1.安装好arcdestop，arcengine环境，可参考：
https://www.cnblogs.com/hjyjack9563-bk/articles/16066361.html
2.本次是arcengine10.1+visual studio2010项目创建：
- 新建项目
- 配置一个全局IFeatureClass m_FeatureClass
- 设置生命周期开始时调试
- 释放
- 获取服务图层数据
- 接口编写

编译，重新生成后，找到.soe文件
打开自己部署好的arcgisserver :
http://127.0.0.1:6080/arcgis/manager
登录后，选择“站点”---->“拓展”---->“添加拓展”，如图
然后找到刚才生成的.soe文件，上传即可完成。
最后在需要的服务的“功能”勾选上所对应的拓展即可，“保存并重新启动”,服务的拓展就完成。
