问题描述

我已经在使用标签库尖锐遇到了一个很奇怪的问题。我用下面所示的代码转换视频文件的评级。

I have encountered a very strange problem while using Taglib sharp. I am changes the rating of video file by using code shown below.

        TagLib.File file = TagLib.File.Create(FULLFILEPATH);
        TagLib.Tag Tag = file.GetTag(TagTypes.Id3v2);
        TagLib.Id3v2.PopularimeterFrame frame = TagLib.Id3v2.PopularimeterFrame.Get((TagLib.Id3v2.Tag)Tag, "WindowsUser", true);
        frame.Rating = 255;
        file.Save();

保存文件，当我打开从性能的视频文件的细节选项卡后，评价似乎并没有被改变。但是，当我再次读取该文件C＃编程，并检查其评级的价值，这是为什么255这样的情况，为什么额定值没有更新？

After saving file when i open the detail tab of video file from properties, rating seems not to be change. But when i again read that file programmatically in c# and check its rating value, it is 255. Why this happening and why rating value is not updating ?

推荐答案

综观答案的的，可能的原因是，您的代码可能会得到保存为iD3v2.4和Windows只支持ID3V2。 3

Looking at the answer to Check music file rating with VB.NET + WinForms, the likely cause is that your tags may be getting saved as iD3v2.4 and Windows only supports iD3v2.3.

您可以强制的TagLib＃保存您的标签，iD3v2.3用下面的代码：

You can force TagLib# to save your tags as iD3v2.3 with the following code:

TagLib.Id3v2.Tag.DefaultVersion = 3;
TagLib.Id3v2.Tag.ForceDefaultVersion = true;
