[ASP.net教程]【ASP.NET 进阶】获取MP3文件信息并显示专辑图片


突发奇想,想弄个显示MP3文件信息和专辑图片的小Demo,个人不是大牛,遂百度之,总算搞定,现分享如下。

主要是依靠2个DLL文件:ID3.dll 和 Interop.Shell32.dll,步骤如下:

1.保存音乐文件到本地

       #region 保存音乐文件到本地        string strMp3 = @"~/upload/musics/";        if (!Directory.Exists(Server.MapPath(strMp3)))        {          Directory.CreateDirectory(Server.MapPath(strMp3));         }        strMp3+= fileMp3.FileName ;        if (File.Exists(Server.MapPath(strMp3)))        {          File.Delete(Server.MapPath(strMp3));        }        fileMp3.SaveAs(Server.MapPath(strMp3));        #endregion  

2.获取音乐文件信息

        #region 获取音乐文件信息        string mp3InfoInterHtml = "";        ShellClass sh = new ShellClass();        Folder dir = sh.NameSpace(Path.GetDirectoryName(Server.MapPath(strMp3)));        FolderItem item = dir.ParseName(Path.GetFileName(Server.MapPath(strMp3)));        mp3InfoInterHtml += "文件名:" + dir.GetDetailsOf(item, 0)+"<br>";        mp3InfoInterHtml += "文件大小:" + dir.GetDetailsOf(item, 1) + "<br>";        mp3InfoInterHtml += "歌曲名:" + dir.GetDetailsOf(item, 21) + "<br>";        mp3InfoInterHtml += "歌手:" + dir.GetDetailsOf(item, 13) + "<br>";        mp3InfoInterHtml += "专辑:" + dir.GetDetailsOf(item, 14) + "<br>";        mp3InfoInterHtml += "时长:" + dir.GetDetailsOf(item, 27) + "<br>";        #endregion

3.显示专辑图片

        #region 显示专辑图片        string picturePath = @"~/image/play_null_img.png";        if (!Directory.Exists(Server.MapPath(@"~/upload/images/")))        {          Directory.CreateDirectory(Server.MapPath(@"~/upload/images/"));        }        // 加载MP3        ID3Info info = new ID3Info(Server.MapPath(strMp3), true);        System.Drawing.Image image = null;        if (info.ID3v2Info.AttachedPictureFrames.Count > 0)        {          image = System.Drawing.Image.FromStream(info.ID3v2Info.AttachedPictureFrames.Items[0].Data);          picturePath = @"~/upload/images/" +DateTime.Now.ToString("yyyyMMddHHmmss")+ ".png";          if (File.Exists(Server.MapPath(picturePath)))          {            File.Delete(Server.MapPath(picturePath));          }          image.Save(Server.MapPath(picturePath));        }        imgMP3.ImageUrl = picturePath;        dMp3.InnerHtml = mp3InfoInterHtml;        #endregion

4.修改文件上传限制

 <httpRuntime maxRequestLength="1048576" executionTimeout="3600" />
