Mp3 Player in C#

Mp3 Player in C# can be created without using a media control. In most of tutorials you’ve learned designing Mp3 player in C# using Windows Media Player control. But in this tutorial we are not going to use that approach.

Tools Required:

1. Visual Studio 2010 or Later version.
2. Pichon desktop app (Optional) for icons. Download it from Here

Steps to Follow:

1. After creating a new project in Windows Forms App in Visual Studio right click on project file and Add a new class file.
2. Name that class as Mp3Player.cs and add the following code.

[DllImport("winmm.dll")]
        private static extern long mciSendString(string lpstrCommand, StringBuilder lpstrReturnString,int uReturnLength,int hwdCallBack);

        public void open(string File)
        {
            string Format = @"open ""{0}"" type MPEGVideo alias MediaFile";
            string command = string.Format(Format,File);
            mciSendString(command, null, 0, 0);
        }
        
        public void play()
        {
            string command = "play MediaFile";
            mciSendString(command, null, 0, 0);
        }
        public void stop()
        {
            string command = "stop MediaFile";
            mciSendString(command, null, 0, 0);
        }

In the above code, mciSendString will handle our commands to Load, Play or Stop our audio file.

Open method will load and prepare the audio file. The play and stop method can be used to play or stop the audio file respectively.

Open the design view of your form and add three buttons to open, play and stop the audio file.

Double click on Open button to create OnClick Event. But before adding the code inside this event, First of all create an instance of Mp3Player class on the top of Form1.cs class like,

private Mp3Player mp3Player = new Mp3Player();

and add the follwing code inside the onClick event of Open button:

using (OpenFileDialog ofd = new OpenFileDialog())
{
ofd.Filter = “Mp3 Files|*.mp3”;
if (ofd.ShowDialog() == DialogResult.OK)
{
mp3Player.open(ofd.FileName);
}
}

This will open a file dialog box to select your mp3 file.

Now go to the On Click event of Play Button and call the play method of Mp3Player class.

mp3Player.play();

Now go to the click event of stop button and call the stop method of Mp3Player class.

mp3Player.stop();
