If (HTag & !_HaveTag) // just delete ID3Īn Mp3 file with ID3 looks something like this figure: This method just reads text from a specified FileStream, according to TextEncoding and the maximum available length.įileStream fs = new FileStream(_FilePath, FileMode.Open) And if the file contains ID3v1, HaveID3 tries to load it.įor reading text, I have used the ' Frame.ReadText' method. The HaveID3 method determines if file contains ID3v1. This method first defines a FileStream to a file and tries to find out if the file contains ID3 data. To load ID3v1 you must use the ' Load()' method. If the programmer wanted to load ID3v1 data in the constructor (With LoadData argument), otherwise load sets information to "". In the constructor, set the _FilePath variable to the path of the file. There's another variable that allows the ID3Info class to know if the current file must contain ID3v1. For example, _Comment does not allow comments to be more than 28 characters. There are some properties for each variable and they check the limitations of ID3v1. The variables in this class hold ID3v1 data. ID3v1 class, in ID3.ID3v1Frames namespace handles ID3v1 jobs.
ID3Info returns Genre number not Genre name.Īs you can see, there's nothing complex in ID3v1. 'TAG' keyword will follow with Title (30 character), Artist (30 Character), Album (30 Character), Year (4 Character), Comment (28 character), Track Number (1 byte) and Genre (1 byte). It starts with 'TAG', this is ID3v1 identifier. The last 128 bytes of file may contain ID3v1 information. I will try to make it better using my own time and other user's ideas. I just wrote the application to find bugs. This application doesn't use more than 60% of ID3Info's power. NET classes (like ArrayList, FileStream, MemoryStream, etc.). To understand how this class works you need to know some basics. In this article my focus is more on ID3v2 because there are too many other good references for ID3v1. The most popular version of ID3 is 2.3.0 and version 1. For ID3v2 minor versions this class can read ID3v2.2, ID3v2.3, ID3v2.4 and can write ID3v2.3 and ID3v2.4. This class can Read/Write both versions of ID3: ID3v1 and ID3v2. I'll just explain the basics of ID3 and how the ID3Info class works. In this article I won't explain the details of ID3. This is the best place to help you understand the details of ID3. To learn how ID3 works in detail, look at The ID3 Homepage. ID3Info is a class that allows you to manage ID3 of files. This information can be: text, files, images, lyrics and much more. ID3 is additional information that attaches to mp3 files.
