本文实例讲述了C#实现HTML和UBB互相转换的方法。分享给大家供大家参考。具体实现方法如下：

html转UBB的还不是很完美，有空修改，一些代码来自百度谷歌，如下所示：

private string DoHtmlToUBB(string _Html)
{

_Html = Regex.Replace(_Html, "<br[^>]*>", "/n");
 _Html = Regex.Replace(_Html, @"<p[^>//]*//>", "/n");
 _Html = Regex.Replace(_Html, "//son[//w]{3,16}//s?=//s*([/'/"]).+?//1", "");
 _Html = Regex.Replace(_Html, "<hr[^>]*>", "[hr]");

_Html = Regex.Replace(_Html, "<(///)?blockquote([^>]*)>", "[$1blockquote]");
 _Html = Regex.Replace(_Html, "<img[^>]*smile=/"(//d+)/"[^>]*>", "'[s:$1]");
 _Html = Regex.Replace(_Html, "<img[^>]*src=[/'/"//s]*([^//s/'/"]+)[^>]*>", "");
 _Html = Regex.Replace(_Html, "<a[^>]*href=[/'/"//s]*([^//s/'/"]*)[^>]*>(.+?)<///a>", "[url=$1]$2[/url]");
 _Html = Regex.Replace(_Html, "(.+?)",@"/[b/]$1/[/b/]");
 _Html = Regex.Replace(_Html, "<[^>]*?>", "");
 _Html = Regex.Replace(_Html, "&", "&");
 _Html = Regex.Replace(_Html, " ", " ");
 _Html = Regex.Replace(_Html, "<", "<");
 _Html = Regex.Replace(_Html, ">", ">");

return _Html;
}
public string ubbtohtml(string content) //ubb转html
{
 content = Regex.Replace(content, @"/r/n", " ");
 content = Regex.Replace(content, " ", " ");
 content = Regex.Replace(content, @"/[b/](.+?)/[/b/]", "$1");
 content = Regex.Replace(content, @"/[i/](.+?)/[/i/]", "$1");
 content = Regex.Replace(content, @"/[u/](.+?)/[/u/]", "$1");
 content = Regex.Replace(content, @"/[p/](.+?)/[/p/]", "$1");
 content = Regex.Replace(content, @"/[align=left/](.+?)/[/align/]", "<align='left'>$1</align>");
 content = Regex.Replace(content, @"/[align=center/](.+?)/[/align/]", "<align='center'>$1</align>");
 content = Regex.Replace(content, @"/[align=right/](.+?)/[/align/]", "<align='right'>$1</align>");
 content = Regex.Replace(content, @"/[url=(?<url>.+?)]/[/url]", "<a href='${url}' target=_blank>${url}</a>");
 content = Regex.Replace(content, @"/[url=(?<url>.+?)](?<name>.+?)/[/url]", "<a href='${url}' target=_blank>${name}</a>");
 content = Regex.Replace(content, @"/[quote](?<text>.+?)/[/quote]", "<div class="quote">${text}</div>");
 content = Regex.Replace(content, @"/[img](?<img>.+?)/[/img]", "<img src='${img}' alt=''/>");
 return content;
}
