以上所有代码都可以用以下标记以声明方式替换:All of the code above can be replaced declaratively with the following markup:

对于这些示例,web.config 文件必须具有以下元素:For these examples, the Web.config file must have the following elements:

注解

<有 >元素中,通常指定一个或多个<选项 >元素,其中每个元素都包含指定如何针对目标设备功能评估选项的属性。Within a <DeviceSpecific> element, you typically specify one or more <Choice> elements, each containing attributes that specify how to evaluate the choice against target device capabilities. 在运行时,将按顺序对每个选项进行计算,并使用成功计算的第一个选择。At run time, each choice is evaluated in order, and the first choice that is successfully evaluated is used. 使用了用来指定模板集和替代属性的选项;例如,它可用于指定 Image 控件的特定于设备的图像。The DeviceSpecific/Choice construct is used to specify template sets and override properties; for example, it can be used to specify device-specific images for the Image control.

备注

即使 DeviceSpecific 类从 Web 窗体 System.Web.UI.Control 命名空间继承,这只是一个实现细节。Even though the DeviceSpecific class inherits from the Web Forms System.Web.UI.Control namespace, this is only an implementation detail. <Choice> 元素的行为与控件不同。A <Choice> element does not behave like a control.
