请问，ASP.net如何把带html格式的内容转换成纯文本的文字
请问，ASP.net如何把带html格式的内容转换成纯文本的文字 --------------------编程问答-------------------- 使用正则表达式对字符串进行过滤 --------------------编程问答----------------------------------------编程问答-------------------- 正则替换<[^>]+>就可以了 --------------------编程问答-------------------- 但是如两位所说， 并未被过滤掉 --------------------编程问答--------------------
public string LostHTML(string Str)
{
string Re_Str = "";
if (Str != null)
{
if (Str != string.Empty)
{
string Pattern = "<\\/*[^<>]*>";
Re_Str = Regex.Replace(Str, Pattern, "");
}
}
return (Re_Str.Replace("\\r\\n", "")).Replace("\\r", "");
}

HiddenField HTitle = e.Item.FindControl("HFTitle") as HiddenField;
Literal ltTitle = e.Item.FindControl("ltTitle") as Literal;
if (HTitle.Value.Length > 30)
{
ltTitle.Text = HTitle.Value.ToString().PadRight(30).Substring(0,30)+"...";

else { ltTitle.Text = HTitle.Value.ToString(); }
我用别人的代码..
补充：.NET技术 , ASP.NET
