原文:ArcGIS Engine开发的ArcGIS 版本管理的功能

转自：http://blog.csdn.net/linghe301/article/details/7965901

这是以前的ArcGIS Engine开发成果，主要是Geodatabase方面的，模仿ArcGIS版本的流程
系统环境：

VS2010、ArcGIS Engine10、DevExpress721（第三方控件，比较常用易于下载）

------------------------------------------------------------------

我跟大家分享了存在#百度网盘#上的文件，“DXperienceEval-7.2.1.exe”，点击链接进行查看和下载。 http://t.cn/zWsdZRY （分享自 @百度网盘官方微博）
------------------------------------------------------------------

系统的连接参数都写在代码里面了，如果有问题，跟踪一下代码即可解决

相关功能：

1：打开ArcSDE版本数据

2：切换版本

3：创建新版本

4：查看版本信息

5：协调版本

6：冲突解决

7：提交版本

8：历史归档管理

因为这是很早的东西了，是自己兴趣开发的，会有相关bug，如果有一定基础肯定可以顺利的进行参考！希望能给大家带来帮助！

仅供参考！
