備註

使用此屬性,以程式設計方式判斷 HTML 伺服器控制項的元素名稱。Use this property to programmatically determine the element name of the HTML server control. 例如,伺服器端 <div id="myDiv" runat=server> 元素的 TagName 屬性包含 "div" 值。For example, the TagName property of the server-side <div id="myDiv" runat=server> element contains the value "div".
