NoSettingsVersionUpgradeAttribute 类

定义

指定设置提供程序应禁用检测到应用程序升级时调用的任何逻辑。Specifies that a settings provider should disable any logic that gets invoked when an application upgrade is detected. 此类不能被继承。This class cannot be inherited.

public sealed class NoSettingsVersionUpgradeAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.Property)>]
type NoSettingsVersionUpgradeAttribute = class
    inherit Attribute
Public NotInheritable Class NoSettingsVersionUpgradeAttribute

注解

若要创建支持应用程序版本控制的功能齐全的应用程序设置提供程序,提供程序必须实现 IApplicationSettingsProvider 接口。To create a fully featured application settings provider that supports application versioning, the provider must implement the IApplicationSettingsProvider interface. 此接口中的一个成员(即 Upgrade 方法)会被调用,通知提供程序已安装了新版本的应用程序。One of the members in this interface, the Upgrade method, is called to notify the provider that a new version of the application has been installed. 在响应中,提供程序应执行相应的操作,通常迁移过去的应用程序设置。In response, the provider is expected to perform an appropriate action, typically migrating past application settings.

NoSettingsVersionUpgradeAttribute通知提供程序取消与当前设置类关联的升级逻辑。The NoSettingsVersionUpgradeAttribute informs the provider to suppress the upgrade logic associated with the current settings class. 因此,此属性组的以前版本的值不应迁移到新安装。Therefore, the value of the previous version of this property group should not be migrated to the new installation.

备注

此属性仅可应用于单个应用程序设置属性。This attribute can only be applied to individual application settings properties.
