Getting size of an audio file in ASP.NET

Given an audio file (mp3 or wav), is here a way to get the duration, size (in bytes) and other other attributes of the file?

Thanks

For file size FileInfo would be worth looking at

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

This gets you the file size

and to 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
  }

I second the NAudio library for finding the duration of a track [in seconds]

Here's aC++ answer from a similar SO post about how to do it without using a library.

time length of an mp3 file

Although the author wanted Python code, he got something else usable. Maybe the logic is what you need.

You can get the file size by writing new FileInfo(path).Length.
If you have it in a stream, you can simply write stream.Length.

To get other information, you'll need audio codecs.

For the duration, you will need a library. I just found this one on google. http://www.codeplex.com/naudio

As for file size look at the System.IO.File class. http://msdn.microsoft.com/en-us/library/system.io.file.aspx
