How to: Loop a Sound Playing on a Windows Form

The following code example plays a sound repeatedly. When the code in the stopPlayingButton_Click event handler runs, any sound currently playing stops. If no sound is playing, nothing happens.

Example

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Media;
using System.Windows.Forms;

namespace SoundPlayerPlayLoopingExample
{
    public class Form1 : Form
    {
        private SoundPlayer Player = new SoundPlayer();

        public Form1()
        {
            InitializeComponent();
        }

        private void playLoopingButton_Click(object sender, EventArgs e)
        {
            try
            {
                // Note: You may need to change the location specified based on
                // the sounds loaded on your computer.
                this.Player.SoundLocation = @"C:\Windows\Media\chimes.wav";
                this.Player.PlayLooping();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message, "Error playing sound");
            }
        }

        private void stopPlayingButton_Click(object sender, EventArgs e)
        {
            this.Player.Stop();
        }

        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// Clean up any resources being used.

        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

            this.Text = "Form1";
            this.ResumeLayout(false);

        }

        #endregion

        private System.Windows.Forms.Button playLoopingButton;
        private System.Windows.Forms.Button stopPlayingButton;
    }

    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.Run(new Form1());
        }
    }
}

Compiling the Code

This example requires:

  • References to the System and System.Windows.Forms assemblies.

  • That you replace the file name "c:\Windows\Media\chimes.wav" with a valid file name.

For information about building this example from the command line for Visual Basic or Visual C#, see Building from the Command Line (Visual Basic) or Command-Line Building. You can also build this example in Visual Studio by pasting the code into a new project. How to: Compile and Run a Complete Windows Forms Code Example Using Visual Studio

Robust Programming

File operations should be enclosed within appropriate exception-handling blocks.

The following conditions may cause an exception:

Security

Do not make decisions about the contents of the file based on the name of the file. For example, the file Form1.vb may not be a Visual Basic source file. Verify all inputs before using the data in your application.
