示例

下面的代码示例演示如何使用 DeviceSpecificChoiceCollection 类获取对可选择的构造中的选项的访问。The following code example shows how to use the DeviceSpecificChoiceCollection class to gain access to the choices in a DeviceSpecific/Choice construct. 为方便起见,包含筛选器的 Web.config 文件遵循示例代码。For your convenience, a Web.config file containing the filters follows the example code.

备注

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,则可能无法正常工作。The following code sample uses the single-file code model and may not work correctly if copied directly into a code-behind file. 必须将此代码示例复制到扩展名为 .aspx 的空文本文件中。This code sample must be copied into an empty text file that has an .aspx extension. 有关详细信息,请参阅ASP.NET Web 窗体页代码模型For more information, see ASP.NET Web Forms Page Code Model.
