HtmlInputControl.Name 属性

  • 参考

定义

命名空间:
System.Web.UI.HtmlControls
程序集:
System.Web.dll

获取或设置 HtmlInputControl 控件的唯一标识符名。

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

属性值

String

一个字符串，表示 UniqueID 属性的值。

示例

下面的代码示例演示如何使用 Name 属性来确定单击的 的名称 HtmlInputControl 。

注解

Name使用 属性确定 的唯一HtmlInputControl标识符名称。 在此实现中 get ，访问器返回 属性的值 Control.UniqueID 。 但是， set 访问器不会为此属性赋值。

注意

访问 set 器不会为此属性赋值，因为 Name 属性必须与 属性具有相同的值， Control.UniqueID 大多数控件才能正常工作。

如有必要，从 类继承的 HtmlInputControl 类可以重写此实现。
