When done before the project, I have encountered a problem that the text should contain some html in html tag removed, and displays Label text above in winform after removal. Then search online for a long time, finally found a point of information, compiled under the control their own good, now for everyone to share:
/// <summary>
/// 清除文本中Html的标签
/// </summary>
/// <param name="Content"></param>
/// <returns></returns>
private string ClearHtml(string Content)
{
Content = Zxj_ReplaceHtml("&#[^>]*;", "", Content);
Content = Zxj_ReplaceHtml("</?marquee[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?object[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?param[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?embed[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?table[^>]*>", "", Content);
Content = Zxj_ReplaceHtml(" ", "", Content);
Content = Zxj_ReplaceHtml("</?tr[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?th[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?p[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?a[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?img[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?tbody[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?li[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?span[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?div[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?th[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?td[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?script[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("(javascript|jscript|vbscript|vbs):", "", Content);
Content = Zxj_ReplaceHtml("on(mouse|exit|error|click|key)", "", Content);
Content = Zxj_ReplaceHtml("<\\?xml[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("<\\/?[a-z]+:[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?font[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?b[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?u[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?i[^>]*>", "", Content);
Content = Zxj_ReplaceHtml("</?strong[^>]*>", "", Content);
string clearHtml = Content;
return clearHtml;
}
}
/// <Summary>

Private String Zxj_ReplaceHtml (PATRN String, String strRep, String Content)
{
IF (String.IsNullOrEmpty (Content))
{
Content = "";
}
the Regex the Regex rgEx new new = (PATRN, RegexOptions.IgnoreCase);
String strTxt = rgEx.Replace (Content, strRep);
return strTxt;
}
