C# CS结构发消息聊天模块，服务端和客户端同时运行，可简单互通消息，实现类似点对点聊天的功能，测试前请输入IP和端口号，登录功能需要服务器配合。

煤矿信息管理系统是基于SuperMap Object，使用 C#语言开发的煤矿信息管理系统 系统主要实现煤矿信息的管理，包括属性数据和图形数据的管理。其中最重要的部分是钻孔数据的管理， 比较理想的解决了钻孔数据的查询、浏览、修改、添加、删除和导出，并着重实现了钻孔剖面示意图的自动绘制， 此外还实现了计算机图件的管理、地图数据集导出、地图输出打印等功能。(Mine information management system is based on SuperMap Object, using the C# Language developed by the Information Management System for Mine realize mine of information systems management, including the attribute data and graphical data management. One of the most important part is the management of borehole data, a more satisfactory solution to the borehole data query, browse, modify, add, delete and export, and focus on the achievement of the drilling section diagram of automatic drawing, in addition to realize a computer management maps, maps derived data sets, maps output printing.)
