ApplicationScopedSettingAttribute 类

定义

指定应用程序设置属性具有适用于应用程序所有用户的公共值。Specifies that an application settings property has a common value for all users of an application. 此类不能被继承。This class cannot be inherited.

public ref class ApplicationScopedSettingAttribute sealed : System::Configuration::SettingAttribute
[System.AttributeUsage(System.AttributeTargets.Property)]
public sealed class ApplicationScopedSettingAttribute : System.Configuration.SettingAttribute
[<System.AttributeUsage(System.AttributeTargets.Property)>]
type ApplicationScopedSettingAttribute = class
    inherit SettingAttribute
Public NotInheritable Class ApplicationScopedSettingAttribute
Inherits SettingAttribute
继承
ApplicationScopedSettingAttribute
属性

注解

应用程序设置属性具有基于应用程序或用户级别的作用域。Application settings properties have a scope that is based either at the application or the user level. 如类别所示,应用程序范围的设置属性向应用程序的所有用户提供统一的值,而用户范围的属性则为应用程序的每个用户提供专用值。As the categories imply, application-scoped settings properties present uniform values to all users of the application, whereas user-scoped properties have dedicated values for each user of the application.

ApplicationScopedSettingAttribute指示应将属性视为应用程序级别设置,并且应根据设置提供程序相应地做出适当的存储决策。The ApplicationScopedSettingAttribute indicates that a property should be considered an application-level setting, and that appropriate storage decisions should be made accordingly by the settings provider.

每个设置属性都需要一个作用域属性。A scope attribute is required for each settings property. 如果属性未应用于 ApplicationScopedSettingAttributeUserScopedSettingAttribute ,则设置提供程序无法识别该属性,因为它不会序列化。If a property is not applied with either a ApplicationScopedSettingAttribute or UserScopedSettingAttribute, the property is not recognized by the settings provider - it is not serialized. 但是,将两个特性应用于同一个属性是无效的。It is invalid, however, to apply both attributes to the same property. 此类尝试将导致 ConfigurationErrorsException 引发。Such an attempt will cause a ConfigurationErrorsException to be thrown.

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.
