C#匹配HTML标签，正则表达式谁会？

JS:
function StripHtml(html)
{
var scriptregex = ".]*>[sS]*?";
var scripts = new RegExp(scriptregex, "gim");
html = html.replace(scripts, " ");

//Stripts the ";
var styles = new RegExp(styleregex , "gim");
html = html.replace(styles, " ");

//Strips the HTML tags from the html
var objRegExp = new RegExp("<(.| )+?>", "gim");
varstrOutput = html.replace(objRegExp, " ");

//Replace all < and > with < and >
strOutput = strOutput.replace(/strOutput = strOutput.replace(/>/, ">");

objRegExp = null;
return strOutput;
}

.NET:

[AjaxPro.AjaxMethod()]
public String UnSafeHTMLFilter(string html)
{
Regex regex1 = new Regex(@"标记
html = regex2.Replace(html, ""); //过滤href=javascript: () 属性
html = regex3.Replace(html, " _disibledevent="); //过滤其它控件的on...事件
html = regex4.Replace(html, ""); //过滤iframe
html = regex5.Replace(html, ""); //过滤frameset
return html;
}
