示例

下面的代码示例在窗体上创建一个控件，并添加两StatusBarPanel个StatusBar对象。 其中一个名为StatusBarPanelpanel1，显示应用程序的状态文本。 第二 StatusBarPanel个，命名 panel2，显示当前日期，并使用 ToolTipText 类的属性 StatusBarPanel 显示当前时间。 该示例使用ShowPanels该属性来确保显示面板而不是标准面板，并且该属性用于Panels访问Add将面板添加到StatusBar其中的方法StatusBar.StatusBarPanelCollection。 该示例还使用 AutoSize、BorderStyle和ToolTipTextText属性初始化StatusBarPanel对象。 本示例假定从示例中定义的方法是从构造 Form函数中定义的并调用的。

注解

类 StatusBar.StatusBarPanelCollection 存储显示在 .. 中的 StatusBar面板。 集合中的每个对象都是类的 StatusBarPanel 实例，该实例定义显示在一 StatusBar个面板中的面板的显示特性和行为。

可通过多种方式将面板添加到集合。 该方法 Add 提供将单个面板添加到集合的功能。 若要向集合添加多个面板，请创建一个对象数组 StatusBarPanel 并将其分配给 AddRange 方法。 如果要在集合中的特定位置插入面板，可以使用该方法 Insert 。 若要删除面板，如果知道面板位于集合中的位置，则可以使用 Remove 该方法或 RemoveAt 方法。 通过此方法 Clear ，你可以从集合中删除所有面板，而不是使用 Remove 该方法一次删除单个面板。

除了用于添加和删除面板的方法和属性外， StatusBar.StatusBarPanelCollection 还提供用于查找集合中的面板的方法。 使用此方法 Contains 可以确定面板是否是集合的成员。 知道面板位于集合中后，可以使用 IndexOf 该方法确定面板位于集合中的位置。
