How to get the length of a music track in C#

Check out this article :

Though its in VB, you can convert it using this tool : http://www.developerfusion.com/tools/convert/vb-to-csharp/[^]

I think you are looking for the

TagLib.File.Properties.Duration

which returns a TimeSpan object. From there you can use TotalSeconds to get the length of the mp3 in seconds.

or go through this link-

If you don't mind dealing with a Shell interop, you can use the GetDetailsOf[^] method.

Problem #1: using the Shell can be frustrating
Problem #2: the list of available file details will be different depending on the version of Windows, so you have to check for that, too.

However, this method can come in very handy, since it returns everything that it knows about the file.

Edit: A good starting example is here: http://www.codeproject.com/KB/files/detailedfileinfo.aspx[]

If you use it (or any other sample you find), increase the "i < 30" when getting the details. It's WAY above 30, now. Try 300, instead.

Am Not Sure One of The Way
Send It to StreamReader or byte array and then find length use (.Length)

If you are talking about MP3 files, you want a way to read the ID3 tags. Here's a good link demonstrating this with a library written for .NET: http://stackoverflow.com/questions/68283/view-edit-id3-data-for-mp3-files[^].

Here is a general purpose media library that can be used from C# as well:
