SecurityCriticalAttribute 类

定义

指定代码或程序集执行安全关键操作。Specifies that code or an assembly performs security-critical operations.

public ref class SecurityCriticalAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Assembly | System.AttributeTargets.Class | System.AttributeTargets.Constructor | System.AttributeTargets.Delegate | System.AttributeTargets.Enum | System.AttributeTargets.Field | System.AttributeTargets.Interface | System.AttributeTargets.Method | System.AttributeTargets.Struct, AllowMultiple=false, Inherited=false)]
[System.AttributeUsage(System.AttributeTargets.Assembly | System.AttributeTargets.Class | System.AttributeTargets.Constructor | System.AttributeTargets.Delegate | System.AttributeTargets.Enum | System.AttributeTargets.Event | System.AttributeTargets.Field | System.AttributeTargets.Interface | System.AttributeTargets.Method | System.AttributeTargets.Module | System.AttributeTargets.Property | System.AttributeTargets.Struct, AllowMultiple=false, Inherited=false)]
public sealed class SecurityCriticalAttribute : Attribute
type SecurityCriticalAttribute = class
    inherit Attribute
Public NotInheritable Class SecurityCriticalAttribute
Inherits Attribute

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.

安全关键操作是影响代码访问安全性的操作,例如通过使用 Assert 方法和调用不安全的托管代码来禁止代码访问安全检查的权限提升。Security-critical operations are actions that affect code access security, such as elevation of privilege through suppression of code access security checks by using the Assert method, calling unsafe managed code, and so forth. 若要执行安全关键操作,必须将 SecurityCriticalAttribute 特性或 @no__t 特性应用到代码。Either the SecurityCriticalAttribute attribute or the SecuritySafeCriticalAttribute attribute must be applied to code for the code to perform security-critical operations.

备注

@No__t-0 等效于完全信任的链接要求。The SecurityCriticalAttribute is equivalent to a link demand for full trust. 标记有 SecurityCriticalAttribute 的类型或成员只能由完全受信任的代码调用;它不必需要特定权限。A type or member marked with the SecurityCriticalAttribute can be called only by fully trusted code; it does not have to demand specific permissions. 它不能由部分受信任的代码调用。It cannot be called by partially trusted code.

在程序集级别应用 SecurityCriticalAttribute 会将程序集标识为安全关键程序集。Applying the SecurityCriticalAttribute at the assembly level identifies the assembly as a security-critical assembly. 可以通过将范围参数设置 SecurityCriticalScope.Everything 来将整个程序集标识为关键。The entire assembly can be identified as critical by setting the scope parameter SecurityCriticalScope.Everything.

构造函数

SecurityCriticalAttribute()

初始化 SecurityCriticalAttribute 类的新实例。Initializes a new instance of the SecurityCriticalAttribute class.

SecurityCriticalAttribute(SecurityCriticalScope)

用指定范围初始化 SecurityCriticalAttribute 类的新实例。Initializes a new instance of the SecurityCriticalAttribute class with the specified scope.

属性

Scope

获取特性的范围。Gets the scope for the attribute.

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)

方法

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()

返回一个表示当前对象的 string。Returns a string that represents the current object.

(继承自 Object)

显式界面实现

_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)

提供对某一对象公开的属性和方法的访问。Provides access to properties and methods exposed by an object.
