C#读取Mp3文件ID3v1标签信息

练习一下C#

参考了网上的一些资料,写了一个类

ID3v1还是比较简单的,也够用了

通过这个也熟悉了读取文件,特别是二进制的文件的方法,还有目录遍历的方法。

下面把源文件贴出来

ID3v1.cs

using System;
using System.Collections.Generic;

        public string album;       //专辑
        public string year;        //年代
        public string comment;     //备注
        public int trackNumberFlag;//编号标记
        public int trackNumber;    //编号
        public int genre;          //类型
    }
