MP3 Media Player in C# 4.0


In this article I describe how to play audio in C# .Net. There are several ways to create a player in C# but in this article I will describe the simplest way to create a MP3 player that plays .mp3 and .wav files only, because I set the Filter property of the opendialog box.

Use the following procedure to create it.

Step 1

  • Open Visual Studio 2010
  • "File" -> "New" -> "Project..."
  • Choose "Template" -> "Visual C#" -> "Windows Form Application "

Step 2

Now add the windows Media Player control in your Toolbox.

  • Right-click in toolbox
  • Select "Choose items"
  • Look for the Windows Media Player within the "COM components" tab of the Choose toolbox Items window



Note: Now the Windows Media Player control is added to your toolbox.

Step 3

Now deign the form as you need to for the control. Here I use a TableLayout panel control on the form and set these properties to "Columncount =1, Dock =Fill and Rows=3".  Now I have inserted the Windows Media Player control from the toolbox in the first row of the TableLayout panel and set the property "Dock=Fill". A list box and button control in the second and third row of the table layout panel with "Dock =Fill" property. And a OpenFileDialog to select one or more .mp3 files to play with the property.


Note: Now your windows look like this:


Step 4

Now write the following C# code in the "Form1.cs" page:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;


namespace media_player


    public partial class Form1 : Form


        public Form1()




        string[] files, path;

        private void button1_Click(object sender, EventArgs e)


            if (openFileDialog1.ShowDialog() ==System.Windows .Forms .DialogResult .OK)


                files = openFileDialog1.SafeFileNames;

                path = openFileDialog1.FileNames;       

                for (int i = 0; i< files.Length; i++)






        private void listBox1_SelectedIndexChanged(object sender, EventArgs e)


            axWindowsMediaPlayer1.URL = path[listBox1.SelectedIndex];





 Step 5

Run your program.
