实现

注解

此权限用于提供对密钥容器的有限访问权限。This permission is used to provide limited access to key containers.

构造函数

KeyContainerPermission(KeyContainerPermissionFlags)

使用指定的访问权限初始化 KeyContainerPermission 类的新实例。Initializes a new instance of the KeyContainerPermission class with the specified access.

KeyContainerPermission(KeyContainerPermissionFlags, KeyContainerPermissionAccessEntry[])

用指定的全局访问和特定的密钥容器访问权限来初始化 KeyContainerPermission 类的新实例。Initializes a new instance of the KeyContainerPermission class with the specified global access and specific key container access rights.

KeyContainerPermission(PermissionState)

用受限制或无限制的权限初始化 KeyContainerPermission 类的新实例。Initializes a new instance of the KeyContainerPermission class with either restricted or unrestricted permission.

属性

AccessEntries

获取与当前权限关联的 KeyContainerPermissionAccessEntry 对象的集合。Gets the collection of KeyContainerPermissionAccessEntry objects associated with the current permission.

Flags

获取密钥容器权限标志,该标志适用于所有与权限关联的密钥容器。Gets the key container permission flags that apply to all key containers associated with the permission.

方法

Assert()

声明调用代码能够通过调用此方法的代码,访问受权限请求保护的资源,即使未对堆栈中处于较高位置的调用方授予访问该资源的权限。Declares that the calling code can access the resource protected by a permission demand through the code that calls this method, even if callers higher in the stack have not been granted permission to access the resource. 使用 Assert() 会引起安全问题。Using Assert() can create security issues.

(继承自 CodeAccessPermission)
Copy()

创建并返回当前权限的相同副本。Creates and returns an identical copy of the current permission.

Demand()

如果未对调用堆栈中处于较高位置的所有调用方授予当前实例所指定的权限,则在运行时强制 SecurityExceptionForces a SecurityException at run time if all callers higher in the call stack have not been granted the permission specified by the current instance.

(继承自 CodeAccessPermission)
Deny()

防止处于调用堆栈较高位置的调用函数使用可以调用此方法来访问当前实例指定资源的代码。Prevents callers higher in the call stack from using the code that calls this method to access the resource specified by the current instance.

(继承自 CodeAccessPermission)
Equals(Object)

确定指定的 CodeAccessPermission 对象是否等于当前的 CodeAccessPermissionDetermines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission.

(继承自 CodeAccessPermission)
FromXml(SecurityElement)

从 XML 编码重新构造具有指定状态的权限。Reconstructs a permission with a specified state from an XML encoding.

GetHashCode()

获取 CodeAccessPermission 对象的哈希代码,此代码适合在哈希算法和数据结构(例如哈希表)中使用。Gets a hash code for the CodeAccessPermission object that is suitable for use in hashing algorithms and data structures such as a hash table.

(继承自 CodeAccessPermission)
GetType()

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

(继承自 Object)
Intersect(IPermission)

创建并返回一个权限,该权限是当前权限与指定权限的交集。Creates and returns a permission that is the intersection of the current permission and the specified permission.

IsSubsetOf(IPermission)

确定当前权限是否为指定权限的子集。Determines whether the current permission is a subset of the specified permission.

IsUnrestricted()

确定当前权限是否无限制。Determines whether the current permission is unrestricted.

MemberwiseClone()

创建当前 Object 的浅表副本。Creates a shallow copy of the current Object.

(继承自 Object)
PermitOnly()

防止处于调用堆栈较高位置的调用函数使用此代码,此代码将调用此方法来访问除当前实例指定的资源以外的所有资源。Prevents callers higher in the call stack from using the code that calls this method to access all resources except for the resource specified by the current instance.

(继承自 CodeAccessPermission)
ToString()

创建并返回当前权限对象的字符串表示形式。Creates and returns a string representation of the current permission object.

(继承自 CodeAccessPermission)
ToXml()

创建权限及其当前状态的 XML 编码。Creates an XML encoding of the permission and its current state.

Union(IPermission)

创建一个权限,该权限是当前权限与指定权限的并集。Creates a permission that is the union of the current permission and the specified permission.
