SocketPermissionAttribute 类

定义

指定安全操作以控制 Socket 连接。Specifies security actions to control Socket connections. 无法继承此类。This class cannot be inherited.

属性

注解

若要使用此属性,Socket 连接必须符合 SocketPermissionAttribute中指定的属性。To use this attribute, your Socket connection must conform to the properties that are specified in your SocketPermissionAttribute. 例如,若要将权限应用于端口80上的 Socket 连接,请将 SocketPermissionAttributePort 属性设置为 "80"。For example, to apply the permission to a Socket connection on port 80, set the Port property of the SocketPermissionAttribute to "80". SocketPermissionAttribute 中指定的安全信息存储在属性目标的元数据中,后者是应用 SocketPermissionAttribute 的类。The security information that is specified in SocketPermissionAttribute is stored in the metadata of the attribute target, which is the class to which the SocketPermissionAttribute is applied. 然后,系统将在运行时访问该信息。The system then accesses the information at run time. 传递给构造函数的 SecurityAction 确定允许的 SocketPermissionAttribute 目标。The SecurityAction that is passed to the constructor determines the allowable SocketPermissionAttribute targets.

备注

SocketPermissionAttribute 的属性的值必须不 nullThe properties of a SocketPermissionAttribute must have values that are not null. 另外,设置后,属性的值将无法更改。Also, once set, the values of the properties cannot be changed.
