You can play a specified MP3 file or an MP3 file in an embedded resource.

The following is the source code of the MP3 operation class I wrote:

1. Import the MP3 file to Vs and set it to an embedded Resource:

 

MP3 files

 

2. import to the resource. C # regards MP3 as the file type and stores it in byte [] format:

 

3. Set the MP3 file as an embedded Resource:

 

4. Create a new form project and call the MP3 class method in the load event to play the music:

 

Private void formmain_load (Object sender, eventargs E)
{// Load the music mp3player MP3 = new mp3player (properties. Resources. Music, handle );

// Start playing mp3.open ();
}
