示例
此示例演示如何为 hostingEnvironment Element (ASP.NET 设置 Schema) 节的多个属性以声明方式指定值，该属性也可以作为类的成员HostingEnvironmentSection进行访问。
以下配置文件示例演示如何以声明方式为 hostingEnvironment 元素 (ASP.NET 设置架构) 部分指定值。
<system.web>
<hostingEnvironment
idleTimeout="20"
shutdownTimeout="30"
/>
</system.web>
下面的代码示例演示如何使用该 HostingEnvironmentSection 类。

注解
该HostingEnvironmentSection类提供了一种以编程方式访问和修改配置文件中节的值HostingEnvironmentSection的方法。当 ASP.NET 应用程序在指定时间内未使用时，可以根据和ShutdownTimeout属性从内存IdleTimeout中卸载该应用程序。
