[QUOTE="hwahrmann, post: 225641, member: 10391"] As per ASF specification you should find the rating as a dword in the ContentDescriptor. The content descriptor should also be there for title, author, etc. But it looks like that no one is using it. WMP inserts some descriptors into the ExtendedContentDescriptors. When you browse a wma file with a hex editor you'll see those as "WM/xxxxxxx". For rating, we're interested in WM/SharedUserRating which is: Stars Value 1 1 2 25 3 50 4 75 5 99 Normally you can get the descriptor strings in taglib# with GetDescriptorStrin. However as the rating is a dword, taglib# does return null. I'll talk to Brian about that. so how to retrieve the value? [CODE] // Get the Generic Tag from the WMA file File tag = File.Create(@"D:\Temp\output.wma"); // Get a tagof type TagLib.Asf.Tag so that we may use the ASF Tag methods TagLib.Asf.Tag asftag = tag.GetTag(TagTypes.Asf) as TagLib.Asf.Tag; // Note: This will not work, because rating is a DWORD and Taglib# only return Unicode Values string rating = asftag.GetDescriptorString("WM/SharedUserRating"); // Because of the above not working, we use the one below to get the rating foreach (TagLib.Asf.ContentDescriptor desc in asftag.GetDescriptors("WM/SharedUserRating")) { if (desc == null) continue; rating = desc.ToString(); } Console.WriteLine(ratin); [/CODE] [/QUOTE]
