定义

指示应用程序设置属性具有特别意义。Indicates that an application settings property has a special significance. 无法继承此类。This class cannot be inherited.

public ref class SpecialSettingAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Property)]
public sealed class SpecialSettingAttribute : Attribute
type SpecialSettingAttribute = class
    inherit Attribute
Public NotInheritable Class SpecialSettingAttribute
Inherits Attribute
继承

属性

注解

某些应用程序设置属性具有特殊的意义,可改变其关联的设置提供程序处理方式。Certain application settings properties have a special significance that alters the way in which their associated settings provider should process them. SpecialSettingAttribute 用于标识此类属性。The SpecialSettingAttribute is used to identify such properties. 此类使用 System.Configuration.SpecialSetting 枚举来指示属性所属的特殊类别。This class uses the System.Configuration.SpecialSetting enumeration to indicate what special category the property belongs to.

SpecialSettingAttribute 只能应用于 settings 类或单个设置属性。SpecialSettingAttribute can only be applied to the settings class or to the individual settings property.

有关设置提供程序如何处理 SpecialSettingAttribute的示例,请参阅 LocalFileSettingsProvider 类的 GetPropertyValues 方法。For an example of how a settings provider deals with the SpecialSettingAttribute, see the GetPropertyValues method of the LocalFileSettingsProvider class.

构造函数

SpecialSettingAttribute(SpecialSetting)

(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.

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)
