WebBrowserPermissionAttribute 类

定义

警告:已过时

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 WebBrowserPermission 执行安全操作。Allows security actions for WebBrowserPermission to be applied to code using declarative security.

public ref class WebBrowserPermissionAttribute sealed : System::Security::Permissions::CodeAccessSecurityAttribute
[System.AttributeUsage(System.AttributeTargets.Assembly | System.AttributeTargets.Class | System.AttributeTargets.Constructor | System.AttributeTargets.Method | System.AttributeTargets.Struct, AllowMultiple=true, Inherited=false)]

示例

下面的示例演示如何要求调用代码具有创建 Web 浏览器控件的无限制权限。The following example shows how to demand that the calling code has unrestricted permission to create a Web browser control.

[WebBrowserPermissionAttribute(SecurityAction.Demand, Level = WebBrowserPermissionLevel.Unrestricted)]
<WebBrowserPermissionAttribute(SecurityAction.Demand, Level:=WebBrowserPermissionLevel.Unrestricted)>
Public Sub Method03()
End Sub

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.

WebBrowserPermissionAttribute 控制 Web 浏览器控件在 Windows Presentation Foundation (WPF) 应用程序中运行的能力。WebBrowserPermissionAttribute controls the ability of a Web browser control to run in a Windows Presentation Foundation (WPF) application. 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 WebBrowserPermissionFor imperative security, use the corresponding permission class, WebBrowserPermission.

XAML 属性用法XAML Attribute Usage

此类通常不在 XAML 中使用。This class is not typically used in XAML.

构造函数

WebBrowserPermissionAttribute(SecurityAction)

使用指定的 WebBrowserPermissionAttribute 初始化 SecurityAction 类的新实例。Initializes a new instance of the WebBrowserPermissionAttribute 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)
Level

WebBrowserPermissionAttribute 获取或设置当前 Web 浏览器权限级别。Gets or sets the current Web browser permission level for the WebBrowserPermissionAttribute.

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)
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

CreatePermission()

创建并返回 WebBrowserPermission 类的新实例。Creates and returns a new instance of the WebBrowserPermission class.

Equals(Object)

返回一个值,该值指示此实例是否与指定的对象相等。Returns a value that indicates whether this instance is equal to a specified object.

(继承自 Attribute)
GetHashCode()

返回此实例的哈希代码。Returns the hash code for this instance.

(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)
MemberwiseClone()

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

(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)
