c#去掉HTML所有标签

这个方法放在公共类中，然后后台调用

public StringBuilder Datatech(string name, string sql)

{

StringBuilder str = new StringBuilder()

DataTable dt = sqlhelper.publicFun("select top 6 * from tb_information where " + sql)

if (dt != null)

{

for (int i = 0i <dt.Rows.Counti++)

{

DataRow dr = dt.Rows[i]

string content = dr["information_Content"].ToString().Trim()

str.Append("<li class='li_KongGe'>" +

"<ul><li>" +

"<img src='images/rili.png' alt=''" + dr["information_Title"] + "'>" +

"<h4>" + Convert.ToDateTime(dr["information_Time"]).ToLongDateString().ToString() + "</h4>" +

"</li>" +

"<li>" +

"<h5><a href='serviceD.html?information_Id=" + dr["information_Id"]+"'>" + dr["information_Title"] + "</a></h5>" +

"<p>" + sqlhelper.ReplaceHtmlTag(content, 40) + "..." + "</p>" +

"</li>" +

"</ul>" +

"</li>")

}

}

return str

}

之所以用string content = dr["information_Content"].ToString().Trim()的作用是去掉所有空格。

去掉html标签: str.replace(/</?[a-zA-Z]+[^><]*>/g,"")

去掉标签里面的属性: str.replace(/<([a-zA-Z]+)\s*[^><]*>/g,"<$1>")

上面方法复制进去就行了。
