備註

使用此建構函式，使用預設值建立和初始化 類別的新實例 HtmlGenericControl 。 它通常用來動態建立伺服器端 <span> 元素。

下表顯示 實例 HtmlGenericControl 的初始屬性值。

屬性 初始值
TagName 「span」 常值字串。

適用於

HtmlGenericControl(String)

使用指定的標記，初始化 HtmlGenericControl 類別的新執行個體。

public:
 HtmlGenericControl(System::String ^ tag);
public HtmlGenericControl (string tag);
new System.Web.UI.HtmlControls.HtmlGenericControl : string -> System.Web.UI.HtmlControls.HtmlGenericControl
Public Sub New (tag As String)

參數

tag
String

要建立這個類別執行個體的項目名稱。

備註

使用此建構函式，使用指定的標記來建立和初始化 類別的新實例 HtmlGenericControl 。 這可讓您動態建立任何不是由 .NET Framework 類別直接表示的 HTML 伺服器控制項專案。

下表顯示 實例 HtmlGenericControl 的初始屬性值。

屬性 初始值
TagName tag 參數的值。

注意

tag如果 參數為 null ，則 TagName 屬性會設定為 String.Empty 。
