SiteIdentityPermission 类
为作为代码来源地的网站定义标识权限。无法继承此类。
**命名空间:**System.Security.Permissions
**程序集:**mscorlib（在 mscorlib.dll 中）
语法
声明
<SerializableAttribute> _
<ComVisibleAttribute(True)> _
Public NotInheritable Class SiteIdentityPermission
Inherits CodeAccessPermission
用法
Dim instance As SiteIdentityPermission
[SerializableAttribute]
[ComVisibleAttribute(true)]
public sealed class SiteIdentityPermission : CodeAccessPermission
[SerializableAttribute]
[ComVisibleAttribute(true)]
public ref class SiteIdentityPermission sealed : public CodeAccessPermission
/** @attribute SerializableAttribute() */
/** @attribute ComVisibleAttribute(true) */
public final class SiteIdentityPermission extends CodeAccessPermission
SerializableAttribute
ComVisibleAttribute(true)
public final class SiteIdentityPermission extends CodeAccessPermission
备注
使用该类可以确保调用方来自某特定网站。仅为来自带有 HTTP、HTTPS 和 FTP 协议的 URL 的代码定义站点标识。站点是 URL 的协议后面的“//”和之后的“/”（如果有）之间的字符串，例如 URL https://www.fourthcoffee.com/process/grind.htm 中的 www.fourthcoffee.com。其中不包括端口号。如果给定的 URL 是 https://www.fourthcoffee.com:8000/，则站点为 www.fourthcoffee.com，而非 www.fourthcoffee.com:8000。
站点可以完全匹配，也可以通过在点分隔符位置使用通配符（“*”）前缀进行匹配。例如，站点名称字符串 *.fourthcoffee.com 与 fourthcoffee.com 和 www.fourthcoffee.com 匹配。如果没有通配符，则站点名称必须是精确匹配。站点名称字符串 * 将与所有站点匹配，但不会与无站点证据的代码匹配。
警告
SiteIdentityPermission 将所有路径的权限授予给该站点，包括 URL 与 IP 地址。若要 Deny 对站点的访问，则必须 Deny 该站点所有可能的路径。例如，如果 www.fourthcoffee.com 的 IP 地址为 192.168.238.241，若要 Deny 对 www.fourthcoffee.com 的访问，则必须 Deny www.fourthcoffee.com、192.168.238.241 以及其他任何可用于访问该站点的路径。处理多路径的更好方法是结合使用 PermitOnly 和 Deny。有关此主题以及结合使用 PermitOnly 和 Deny 的更多信息，请参见 使用 Deny 方法 主题中的 Canonicalization Problems Using Deny。
提示
在 .NET Framework 1.0 和 1.1 版中，标识权限不能具有 Unrestricted 权限状态值。在 .NET Framework 2.0 版中，标识权限可以具有任何权限状态值。这意味着在 2.0 版中，标识权限与实现 IUnrestrictedPermission 接口的权限具有相同的行为。有关使用 1.1 版 CAS 策略执行 2.0 版应用程序的信息，请参见 <legacyV1CASPolicy> 元素。
