注解

基于公共语言运行时启动时所建立的主机保护首选项, 使用特性来确定是否可以加载类型或成员。HostProtectionAttributeA HostProtectionAttribute attribute is used to determine if a type or member can be loaded, based on the host's protection preferences established when the common language runtime is started. 如果调用具有活动HostProtectionAttribute的类型或成员, 则该保护特性会出现链接请求。If a type or member with an active HostProtectionAttribute is called, a link demand occurs for that protection attribute. 如果调用方不满足主机保护的需求, HostProtectionException则会引发。If the caller does not meet the demand for host protection, a HostProtectionException is thrown.

备注

HostProtectionAttribute不是权限, 即使它是链接请求的目标。A HostProtectionAttribute is not a permission, even though it is the target of a link demand. 由于链接HostProtectionException请求引发了, 因此无法对其进行处理, 因此不能在代码中对其进行捕获和处理。Because a HostProtectionException is thrown for a link demand, it cannot be handled, and therefore it cannot be trapped and processed in code.
