发帖数: 1750 | 2 一个.Net 面试问道的问题，一直没想到很满意的答案，写上来，看看各位达人有什么
建议。
用程序来实现一个many-to-many的数据表：一个employee可以有N个manager,一个
manager有N个employee.Manager也是一种employee 假设用户名就是Unique ID
要求：
1.实现如下几个函数:GetAllManager(),GetAllManager(strName),GetAllEmployee()，
GetAllEmployee(strName).
2. 不要写专门的类去实现manager和emplyee.
3. 尽量用.Net里的data type.
4. 保证少占内存和执行速度。 |
