Getting the size of an audio file in ASP.NET

Question

Given the sound file (mp3 or wav), can you get the duration, size (in bytes) and other file attributes here?

thank

Answer 1

For file size FileInfo is worth a look

System.IO.FileInfo file = new System.IO.FileInfo(string filename);
long fileSize = file.Length;

This will give you the file size.

and get attributes like hidden status. something like the following can get it

  if (file.Attributes & System.IO.FileAttributes.Hidden == System.IO.FileAttributes.Hidden)
  {
       // hidden file
  }

In the second NAudio library to search for track duration [in seconds]
