C#Amr轉MP3

 

一：打開管理NuGet程序包進行安裝NReco.VideoConverter.dll

 

二：實踐

        /// <summary>
        /// amr轉化為mp3
        /// </summary>
        /// <param name="model"></param>

        {
            if (model.FileType == 2)
            {
                var filePath = Config.FilePath + "\\" + model.FilePath;
                var newFilePath = Config.FilePath + "\\" + model.FilePath.Replace(".amr", ".mp3");

                //萬企鏈傳amr,需轉化為mp3
                if (".amr".Equals(model.FileExt, StringComparison.OrdinalIgnoreCase))
                {
                    //轉MP3
                    if (File.Exists(filePath) && !File.Exists(newFilePath))
                    {
                        CommonMethod.FormatConversion(filePath, "amr", newFilePath, "mp3");
                    }
                }
            }
        }
