推荐答案

这是一个非常普遍的问题，网络上必须有数百篇有关如何做到这一点的文章，并且要深入探讨在每本ASP.NET书籍中，每本都印刷.您是否在寻找有关此的文章?懒得买书看书?

这样做的代码甚至无法在论坛回复中找到.论坛最适合尝试自己工作但发现需要特定帮助的程序员.

This is a very common problem, there must be hundreds of articles on the web on how to do this, as well as being somethign that is thoroughly covered in every ASP.NET book every printed. Have you bothered looking for articles on this ? Bothered to buy a book and read it ?

There is no way the code to do this would even fit in a forum reply. Forums are best for programmers who try to do their own work, but find they need specific help.
