AdRotator 构造函数

定义

初始化 AdRotator 类的新实例。

public:
 AdRotator();
public AdRotator ();
Public Sub New ()

示例

下面的代码示例演示如何创建和初始化 类的新实例 AdRotator 。 然后,新 AdRotator 控件将添加到 Control.Controls 控件的 PlaceHolder 集合中,并显示在“Web 窗体”页上。

注意

下面的代码示例使用单文件代码模型,如果直接复制到代码隐藏文件中,可能无法正常工作。 必须将此代码示例复制到扩展名为 .aspx 的空文本文件中。 有关 Web 窗体代码模型的详细信息,请参阅 ASP.NET Web 窗体页代码模型
