Keyword 如何在页面中包含元关键字和元描述？

我有以下代码：

<%@ Page Title="Spam Filter, Free Exchange Spam Filter – Software to Stop Spam" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="ContentBreadCrumb" Runat="Server">
    Welcome to > <a href="Default.aspx">Home</a>
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="ContentBodyMain" Runat="Server">

您可以使用该控件。在.aspx文件中写入：

<asp:HtmlMeta ID="descriptionMeta" runat="server" />
<asp:HtmlMeta ID="keywordMeta" runat="server" />

this.descriptionMeta.Name = "description";
this.descriptionMeta.Content = "description of the page or whatever";
this.keywordMeta.Name = "keywords";
this.keywordMeta.Content = "some,keywords,and,things";
