HtmlInputControl.Name 屬性

  • 參考

定義

命名空間:
System.Web.UI.HtmlControls
組件:
System.Web.dll

取得或設定 HtmlInputControl 控制項的唯一識別項名稱。

public:
 virtual property System::String ^ Name { System::String ^ get(); void set(System::String ^ value); };
public virtual string Name { get; set; }
member this.Name : string with get, set
Public Overridable Property Name As String

屬性值

String

字串，表示 UniqueID 屬性的值。

範例

下列程式碼範例示範如何使用 Name 屬性來判斷已按一下的 HtmlInputControl 名稱。

備註

Name使用 屬性來判斷 的唯一 HtmlInputControl 識別碼名稱。 在此實作中，存取 get 子會傳回 屬性的值 Control.UniqueID 。 不過，存取 set 子不會將值指派給這個屬性。

注意

存取 set 子不會將值指派給這個屬性， Name 因為屬性必須具有與屬性相同的值 Control.UniqueID ，大部分控制項才能正常運作。

如有需要，繼承自 類別的 HtmlInputControl 類別可以覆寫此實作。
