C#中HTML和UBB互相转换的代码

C#中HTML和UBB互相转换的代码html转UBB的还不是很完美，有空修改，一些代码来自百度谷歌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>(.+?)</b>",@"/[b/]$1/[/b/]"); _Html = Regex.Replace(_Html, "<[^>]*?>", ""); _Html = Regex.Replace(_Html, "&amp;", "&"); _Html = Regex.Replace(_Html, "&nbsp;", " "); _Html = Regex.Replace(_Html, "&lt;", "<"); _Html = Regex.Replace(_Html, "&gt;", ">"); return _Html; } public string ubbtohtml(string content) //ubb转html { content = Regex.Replace(content, @"/r/n", "<br/>"); content = Regex.Replace(content, " ", "&nbsp;"); content = Regex.Replace(content, @"/[b/](.+?)/[/b/]", "<b>$1</b>"); content = Regex.Replace(content, @"/[i/](.+?)/[/i/]", "<i>$1</i>"); content = Regex.Replace(content, @"/[u/](.+?)/[/u/]", "<u>$1</u>"); content = Regex.Replace(content, @"/[p/](.+?)/[/p/]", "<p class='load'>$1</p>"); 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; }
