TrustSection 类
定义
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
配置应用于应用程序的代码访问安全级别。 此类不能被继承。

示例
本部分提供两个代码示例。 第一个演示如何以声明方式指定类的 TrustSection 多个属性的值。 第二个演示了如何使用类型 TrustSection 。
以下配置文件示例演示如何以声明方式指定类的 TrustSection 多个属性的值。
<system.web>
<trust level="Full" originUrl=""/>
</system.web>
下面的代码示例演示如何使用该 TrustSection 类型。
