Question

自从“SetConfigurationSettingPublisher”被删除后，你怎么能在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();
      }
    }
  };
}

）;

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

CloudStorageAccount.SetConfigurationSettingPublisher已被删除。相反，StorageCredentials的成员现在是可变的，允许用户通过简单地通过提供的UpdateKey方法改变与给定客户端相关联的StorageCredentials实例，以更简化的方式完成类似的场景。

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，则可以按RoleEnvironment.Changing和RoleEnvironment.Changed中所述订阅Read Configuration Settings for the Storage Client Library and Handle Changed Settings和Responding to Role Topology Changes个事件。
