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; }
