实验题目

开发一个采用XML格式存储数据的学生通讯录myContracts，具备学生信息添加，编辑、删除、查找等功能。学生通讯录myContracts是一个多窗体桌面程序，不同窗体上面分别布置了工具条、按钮、数据列表等控件，便于操作学生信息。

实验总结

本次实验整体代码难度不高，主要运用了调用XML文件的功能，主要实现运用C#对XML文件进行操作，其中包括对文件的添加，编辑，删除，查找等操作，还有就是对VS中的各种插件的熟练运用，对其功能的熟悉是实现这个实验的关键。
最后就是对于扩展的功能也是插件的使用，在插件的函数中插入查找的功能便能对其专业信息进行分类输出，备份和恢复的功能可以直接调用XML文件的文件拷贝函数就可以进行备份和恢复。
一些其他功能比如可以对学号进行排序，这个也是可以实现的，只是还没有在程序中进行实现，这个得加以改进。
