获取mp3文件的持续时间 [英] Get duration of mp3 file

问题描述

我正在使用ASP.NET和C＃.NET 2.0。我在gridview中显示名为Sandler的文件夹的所有mp3文件。我想在gridview中显示每个mp3文件的持续时间。我尝试了但是我没有得到解决方案。



这是我的代码：

Hi, I am using ASP.NET and C#.NET 2.0. I am showing all the mp3 files of a folder called "Sandler" in a gridview. I want to display the duration of each mp3 file in the gridview. I tried but I didn''t get the solution.

Here is my code:

public void GetSandlerTrainingFiles()
{ 

String FileName="";
string[] filePaths = System.IO.Directory.GetFiles(Server.MapPath("sandler"/));

             List<listitem> files = new List<listitem>();
            foreach (string filePath in filePaths)
            {
                string p = filePath;
                string fileExt=Path.GetExtension(p);
                if (fileExt == ".mp3")
                {
                    files.Add(new ListItem(Path.GetFileName(filePath), filePath));
                }
            }


            dgrid_sandlertraining.DataSource = files;
            dgrid_sandlertraining.DataBind();
}

现在我想在gridview中显示音频文件的持续时间。这只能在.NET 2.0中完成。



请帮帮我。

推荐答案

我遇到了Windows计算持续时间错误的问题 - 特别是如果它们是VBR。

我使用 UltraId3 [ ^ ]读取元数据，因为这通常更准确。

I have had issues with Windows calculating the duration incorrectly - especially if they are VBR.
I use UltraId3[^] to read the meta data as that is usually more accurate.
