C#实现HTML和UBB互相转换的方法

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>(.+?)</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; }

希望本文所述对大家的C#程序设计有所帮助。
