asp.net razor 如何去掉html标签，只显示文字?

Question

asp.net razor 如何去掉html标签，只显示文字并限制最多字数? 如下图。

Answer 1

这种东西一般就是，要么不考虑性能什么的，用正则，简便；要么就找专门的HTML解析程序。。。

Answer 2

//去掉html标签函数
@functions{
    public static string RemoveHtml(String html)
    {
        string text = System.Text.RegularExpressions.Regex.Replace(html, "<[^>]+>", "");
        text = System.Text.RegularExpressions.Regex.Replace(text, "&[^;]+;", "");
        return text;
    }
}

//其他页面调用函数（helpers为函数的页面名字）
@helpers.RemoveHtml(item.Content)}

Answer 3

写个正则过滤掉html标签 后台过滤：

//删除脚本
Htmlstring = Regex.Replace(Htmlstring, @"<script[^>]*?>.*?</script>", "", RegexOptions.IgnoreCase);
//删除<style></style>样式
Htmlstring = Regex.Replace(Htmlstring, @"<style[^>]*?>[\s\S]*?</style>", "", RegexOptions.IgnoreCase);
//删除HTML
Htmlstring = Regex.Replace(Htmlstring, @"<(?!img|p|/p|br).*?>", "", RegexOptions.IgnoreCase);
//Htmlstring = Regex.Replace(Htmlstring, "/(?<=\" )style=\".*?\"/", "", RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, "style=\".+?\"", "", RegexOptions.IgnoreCase);
//Htmlstring = Regex.Replace(Htmlstring, @"([\r\n])[\s]+", "", RegexOptions.IgnoreCase);
//Htmlstring = Regex.Replace(Htmlstring, @"-->", "", RegexOptions.IgnoreCase);
//Htmlstring = Regex.Replace(Htmlstring, @"<!--.*", "", RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @"&(quot|#34);", "\"", RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @"&(amp|#38);", "&", RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @"&(lt|#60);", "<", RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @"&(gt|#62);", ">", RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @"&(nbsp|#160);", " ", RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @"&(iexcl|#161);", "\xa1", RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @"&(cent|#162);", "\xa2", RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @"&(pound|#163);", "\xa3", RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @"&(copy|#169);", "\xa9", RegexOptions.IgnoreCase);
Htmlstring = Regex.Replace(Htmlstring, @"&#(\d+);", "", RegexOptions.IgnoreCase);
//Htmlstring.Replace("<", "");
//Htmlstring.Replace(">", "");
//Htmlstring.Replace("\r\n", "");
// Htmlstring = HttpContext.Current.Server.HtmlEncode(Htmlstring).Trim();
return Htmlstring;

去网上找个正则去掉文本中的html标签，再截取长度

参考http://blog.csdn.net/gulijiang2008/article/details/7190281中的
