html标记<变为&lt？_ASP.NET

html标记<变成&lt？？
我在后台写的是“<”,然后把它输出到前台就变成"&lt"了~~这个问题怎么解决啊？

绑定控件，设置HtmlEncode="false"即可

探讨
你使用什么控件显示的？

<asp:BoundField HtmlEncode="false"

serverdecode();

这样

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[0].Text = Server.HtmlDecode(e.Row.Cells[0].Text);
}
}
