asp.net关于长文章的分页问题。

Question

 现在的问题是关于内容页中的 html 代码。如果实现分页，容易被截断出现问题，请问这个问题如何解决。谢谢各位！

Answer 1

添加分页标识，split
或过滤HTML分页

Answer 2

手动分页是最方便的，如果你要自己分页的话，告诉你一个思路：就是按照标签符和字符来分割，而不是单纯根据字符数，例如"<"开始后一定要到">"结束。这样才能保证HTML的完整。

Answer 3

手动分页就是在你文章中添加一些标识例如“111111 <#page#>111112”判断的时候发现<#page#>就分页。

各位大哥能给我一个例子参考一下吗？ 我不明白各位所说的手动分页是什么意思啊！还请指教一下。谢谢。
手动分页就是在你文章中添加一些标识例如“111111 <#page#>111112”判断的时候发现<#page#>就分页。
是不是我在添加文章的时候都要在添加文章的时候写上 “ 一些标识例如“111111 <#page#>111112” ”啊。

Answer 6

晕倒。你在文章中插入<#page#> 就可以了。
这样111111 是第一页。111112就是第二页啊。你在编辑框里面添加一个按钮，点击按钮，就在编辑框插入<#page#> 就可以了。
