Get duration of mp3 file

ASP.NET

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();
}

Now I want to display audio file duration in gridview. This is to be done only in .NET 2.0.

Please help me.

Thanks
