注解

重要

不再支持部分受信任的代码。Partially trusted code is no longer supported. 此属性在 .NET Core 中不起作用。This attribute has no effect in .NET Core.

仅为 Url 中的代码和 HTTP、HTTPS 和 FTP 协议定义站点标识。Site identity is only defined for code from URLs with the protocols of HTTP, HTTPS, and FTP. 站点是 URL 协议后面的 "//" 之间的字符串和以下 "/" (如果存在,例如, www.fourthcoffee.com url 中的) http://www.fourthcoffee.com/process/grind.htmA site is the string between the "//" after the protocol of a URL and the following "/", if present, for example, www.fourthcoffee.com in the URL http://www.fourthcoffee.com/process/grind.htm. 这不包括端口号。This excludes port numbers. 如果给定的 URL 为 http://www.fourthcoffee.com:8000/ ,则该站点为 www.fourthcoffee.com ,而不是 www.fourthcoffee.com:8000If a given URL is http://www.fourthcoffee.com:8000/, the site is www.fourthcoffee.com, not www.fourthcoffee.com:8000.

站点可以精确匹配,也可以通过通配符 ( " * " ) 前缀。Sites can be matched exactly, or by a wildcard ("*") prefix at the dot delimiter. 例如,站点名称字符串 *.fourthcoffee.com 匹配 fourthcoffee.comwww.fourthcoffee.comFor example, the site name string *.fourthcoffee.com matches fourthcoffee.com as well as www.fourthcoffee.com. 如果没有通配符,则站点名称必须是精确匹配。Without a wildcard, the site name must be a precise match. 站点名称字符串 * 将匹配任何站点,但不会与没有站点证据的代码匹配。The site name string * will match any site, but will not match code that has no site evidence.

重要

从开始 .NET Framework 4.NET Framework 4 ,不使用标识权限。Starting with the .NET Framework 4.NET Framework 4, identity permissions are not used.

在 .NET Framework 版本1.0 和1.1 中,即使调用程序集是完全受信任的,对标识权限的要求仍有效。In the .NET Framework versions 1.0 and 1.1, demands on the identity permissions are effective even when the calling assembly is fully trusted. 也就是说,尽管调用程序集具有完全信任,但如果程序集不满足要求的条件,则标识权限的请求会失败。That is, although the calling assembly has full trust, a demand for an identity permission fails if the assembly does not meet the demanded criteria. 在 .NET Framework 版本2.0 中,如果调用程序集具有完全信任,则标识权限要求将无效。In the .NET Framework version 2.0, demands for identity permissions are ineffective if the calling assembly has full trust. 这将确保所有权限的一致性,从而不会将标识权限视为一种特殊情况。This assures consistency for all permissions, eliminating the treatment of identity permissions as a special case.

允许的声明的范围取决于所 SecurityAction 使用的。The scope of the declaration that is allowed depends on the SecurityAction that is used.

安全特性声明的安全信息存储在属性目标的元数据中,由系统在运行时进行访问。The security information declared by a security attribute is stored in the metadata of the attribute target and is accessed by the system at run time. 安全特性仅用于声明性安全。Security attributes are used only for declarative security. 对于命令性安全,请使用相应的权限类。For imperative security, use the corresponding permission class.

构造函数

SiteIdentityPermissionAttribute(SecurityAction)

使用指定的 SiteIdentityPermissionAttribute 初始化 SecurityAction 类的新实例。Initializes a new instance of the SiteIdentityPermissionAttribute class with the specified SecurityAction.

属性

(继承自 Attribute)
Match(Object)

当在派生类中重写时,返回一个指示此实例是否等于指定对象的值。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(继承自 Attribute)

(继承自 Object)
ToString()

返回表示当前对象的字符串。Returns a string that represents the current object.

(继承自 Object)

显式接口实现

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

将一组名称映射为对应的一组调度标识符。Maps a set of names to a corresponding set of dispatch identifiers.

(继承自 Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

检索对象的类型信息,然后可以使用该信息获取接口的类型信息。Retrieves the type information for an object, which can be used to get the type information for an interface.

(继承自 Attribute)
_Attribute.GetTypeInfoCount(UInt32)

检索对象提供的类型信息接口的数量(0 或 1)。Retrieves the number of type information interfaces that an object provides (either 0 or 1).

(继承自 Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)
