该
HtmlMeta
控件提供对服务器上的 HTML
<meta>
元素的编程访问。 HTML
<meta>
元素是有关呈现页面的数据的容器，但不是页面内容本身。 标记
<meta>
放置在开始和结束 HTML
<head>
元素之间。 每个
<meta>
元素描述元数据属性名称及其关联值。
HtmlMeta
使用控件的属性
Name
指定元数据属性名称，以及
Content
用于指定元数据属性值的属性。 使用该
Scheme
属性可向用户代理指定有关如何解释元数据属性的其他信息。
HttpEquiv
使用 HTTP 检索生成的元数据属性时，使用属性代替
Name
属性。
可以使用对象的属性获取对页面
<head>
元素
Header
的
Page
引用。
