求: C#与ACCESS合作之案例

Question

    在网上搜索了C#的案例,但都是与SQL相连的案例,作为初学者,学习了ACCESS 与C# 我想找些两者合作之案例,不知有哪能位高人能指点一二啊???!!!

Answer 1

用MSSQL是一样的，如果不涉及复杂的操作的话！

Answer 2

谢谢!! 但关键是要求是ACCESS 唉!!

Answer 3

网上应该有啊，CSDN下载就应该有，ACCESS和SQL SERVER的，用工厂模式的

Answer 4

C#的我不知道，有VB.NET的http://bingning.net/VB/SOURCE/database/access.html自定义类，参考一下。

Answer 5

和控制SQL一样，只是SQLConnection，SQLCommand等换成OleDBConnection,OleDBCommand
连接字符串要不会写的话你先手动绑定一个，看一下自动生成的字符串就OK了。
一切都和SQL一样用。

Answer 6
