ContextStaticAttribute 类

定义

指示某静态字段的值对于特定上下文是唯一的。Indicates that the value of a static field is unique for a particular context.

public ref class ContextStaticAttribute : Attribute
[System.AttributeUsage(System.AttributeTargets.Field, Inherited=false)]
[System.Runtime.InteropServices.ComVisible(true)]
[System.Serializable]
public class ContextStaticAttribute : Attribute
type ContextStaticAttribute = class
    inherit Attribute
Public Class ContextStaticAttribute
Inherits Attribute
继承
ContextStaticAttribute
属性

注解

标记为的ContextStaticAttribute静态字段不在上下文之间共享。A static field marked with ContextStaticAttribute is not shared between contexts. 如果在不同的上下文中访问指示的静态字段, 则该字段将包含不同的值。If the indicated static field is accessed on a different context, it will contain a different value. 按原样使用此属性, 不从其派生。Use this attribute as it is, and do not derive from it.

下面的示例显示了此属性的语法:The following example shows the syntax of this attribute:

[ContextStatic][ContextStatic]

静态 int f = 7;static int f=7;

构造函数

ContextStaticAttribute()

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

属性

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.
