.net - Azure 存储 sdk v1.3 到 v2 => SetConfigurationSettingPublisher

Question

自从“SetConfigurationSettingPublisher”被删除后，如何在 Azure 存储 v2.0 中转换它？

CloudStorageAccount.SetConfigurationSettingPublisher( 
( configName, configSetter ) =>
{
  // Provide the configSetter with the initial value
  configSetter( RoleEnvironment.GetConfigurationSettingValue( configName ) );

  RoleEnvironment.Changed += ( sender, arg ) =>
  {
    if( arg.Changes.OfType<RoleEnvironmentConfigurationSettingChange>( ).Any( (change) => 
        ( change.ConfigurationSettingName == configName ) ) )
    {
      // The corresponding configuration setting has changed, so propagate the value
      if( !configSetter( RoleEnvironment.GetConfigurationSettingValue( configName ) ) )
      {
        // In this case, the change to the storage account credentials in the
        // service configuration is significant enough that the role needs to be
        // recycled in order to use the latest settings (for example, the 
        // endpoint may have changed)
        RoleEnvironment.RequestRecycle();
      }
    }
  };
}

);

谢谢

根据Windows Azure Storage Client Library 2.0 Breaking Changes & Migration Guide :

CloudStorageAccount.SetConfigurationSettingPublisher has been removed. Instead the members of StorageCredentials are now mutable allowing users to accomplish similar scenarios in a more streamlined manner by simply mutating the StorageCredentials instance associated with a given client(s) via the provided UpdateKey methods.

根据您的应用程序的要求，您可以直接使用 CloudConfigurationManager.GetSetting() 方法，如 Upgrading to Azure Storage Client 2.0 中所述。 :

var someSetting = CloudConfigurationManager.GetSetting(settingKey);

如果您需要在角色实例运行时响应配置更改，可以订阅 RoleEnvironment.Changing和 RoleEnvironment.Changed Read Configuration Settings for the Storage Client Library and Handle Changed Settings中描述的事件和 Responding to Role Topology Changes .
