定义

注意

Code Access Security is not supported or honored by the runtime.", DiagnosticId="SYSLIB0003", UrlFormat="https://aka.ms/dotnet-warnings/{0}

允许对要使用声明性安全应用到代码中的 DataProtectionPermission 执行安全操作。Allows security actions for DataProtectionPermission to be applied to code using declarative security. 此类不能被继承。This class cannot be inherited.

属性

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.

允许的声明的作用域取决于所使用的 SecurityAction 值。The scope of the declaration that is allowed depends on the SecurityAction value 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. DataProtectionPermissionAttribute 仅用于声明性安全。DataProtectionPermissionAttribute is used only for declarative security. 对于命令性安全,请使用 DataProtectionPermission 类。For imperative security, use the DataProtectionPermission class.

构造函数

DataProtectionPermissionAttribute(SecurityAction)

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

属性

Action

获取或设置安全性操作。Gets or sets a security action.

(继承自 SecurityAttribute)
Flags

获取或设置数据保护权限。Gets or sets the data protection permissions.

ProtectData

获取或设置一个值,该值指示是否可使用 ProtectedData 类来加密数据。Gets or sets a value indicating whether data can be encrypted using the ProtectedData class.

ProtectMemory

获取或设置一个值,该值指示是否可使用 ProtectedMemory 类来加密内存。Gets or sets a value indicating whether memory can be encrypted using the ProtectedMemory class.

TypeId

在派生类中实现时,获取此 Attribute 的唯一标识符。When implemented in a derived class, gets a unique identifier for this Attribute.

(继承自 Attribute)
UnprotectData

获取或设置一个值,该值指示是否可使用 ProtectedData 类解密数据。Gets or sets a value indicating whether data can be unencrypted using the ProtectedData class.

UnprotectMemory

获取或设置一个值,该值指示是否可使用 ProtectedMemory 类解密内存。Gets or sets a value indicating whether memory can be unencrypted using the ProtectedMemory class.

Unrestricted

获取或设置一个值,该值指示是否声明了对受该特性保护的资源有完全(无限制的)权限。Gets or sets a value indicating whether full (unrestricted) permission to the resource protected by the attribute is declared.

(继承自 SecurityAttribute)

方法

(继承自 Attribute)
GetType()

获取当前实例的 TypeGets the Type of the current instance.

(继承自 Object)
IsDefaultAttribute()

在派生类中重写时,指示此实例的值是否是派生类的默认值。When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(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)
