C# 表达式编码器：编码后更改文件名

我正在使用Microsoft Expression Encoder，这是我的代码

using (LiveJob job = new LiveJob())
        {
            // Creates file source for encoding
            LiveFileSource fileSource = job.AddFileSource(DataDirectory);

            // Sets playback to loop on reaching the end of the file
            fileSource.PlaybackMode = FileSourcePlaybackMode.Jump;


            // Sets this source as the current active one
            job.ActivateSource(fileSource);

            job.ApplyPreset(LivePresets.VC1IISSmoothStreamingLowBandwidthStandard);


            PushBroadcastPublishFormat format = new PushBroadcastPublishFormat();
            format.PublishingPoint = new Uri(PublishPoint);
            job.PublishFormats.Add(format);

            // Starts encoding
            job.StartEncoding();
   }

这段代码对目录中的文件列表进行编码，当他完成一个目录时，他会跳到下一个目录

我想做的是在传递到另一个文件之前更改编码后的文件名

我添加了这个方法，我不知道它是否有效

public void liveJob_Status(object sender, EncodeStatusEventArgs e)
    {
        if (e.Status == EncodeStatus.Jumped)
        { LiveFileSource file = (LiveFileSource)e.LiveSource; 
          string name = file.Name;
          string modified_name = "Encode" + name;

          File.Move(DataDirectory + @"\" + name, DataDirectory + @"\" + name.Replace(name, modified_name)); 
        }
    }
