TabPage.GetTabPageOfComponent(Object) 方法

定义

命名空间:

System.Windows.Forms

程序集:

System.Windows.Forms.dll

检索包含指定对象的选项卡页。

public:
 static System::Windows::Forms::TabPage ^ GetTabPageOfComponent(System::Object ^ comp);

public static System.Windows.Forms.TabPage GetTabPageOfComponent (object comp);

public static System.Windows.Forms.TabPage? GetTabPageOfComponent (object? comp);

static member GetTabPageOfComponent : obj -> System.Windows.Forms.TabPage

Public Shared Function GetTabPageOfComponent (comp As Object) As TabPage

参数

comp

Object

要查找的对象。

返回

TabPage

包含指定对象的 TabPage，如果无法找到该对象则为 null。

示例

下面的代码示例创建一个包含两TabPage个TabControl对象的对象，每个对象包含一个Button组件。 button2参数将GetTabPageOfComponent传递给方法，该方法检索TabPage包含 button2。 若要验证检索正确的选项卡页，该SelectedIndex属性会将包含button2设置为TabPage当前选定的选项卡页。
