Step 1: Create a new windows application. Open Visual Studio > File > New > Project > Windows Application > Rename it to ‘WindowsPlayAudio’.
Step 2: Drag and drop a label, 2 button controls and an OpenFileDialog component to the form. Rename them as follows :
Label1 – lblFile
Button1 – btnOpen
Button2 – btnPlay
TextBox – txtFileNm
OpenFileDialog – Set the Filter to ‘WAV Files|*.wav’
In the Form1.cs, add the following namespace
C#
using System.Media;
VB.NET
Imports System.Media
Step 3: On the ‘btnOpen’ click, display File Open dialog box and accept the selected .wav file in the txtFileNm textbox
C#
if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                txtFileNm.Text = openFileDialog1.FileName;
            }
VB.NET
If openFileDialog1.ShowDialog() = System.Windows.Forms.DialogResult.OK Then
            txtFileNm.Text = openFileDialog1.FileName
 End If
Step 4: Code the btnPlay click event to play the selected file asynchronously
C#
private void btnPlay_Click(object sender, EventArgs e)
        {
            if (txtFileNm.Text != String.Empty)
            {
                SoundPlayer wavPlayer = new SoundPlayer();
                wavPlayer.SoundLocation = txtFileNm.Text;
                wavPlayer.LoadCompleted += new AsyncCompletedEventHandler(wavPlayer_LoadCompleted);
                wavPlayer.LoadAsync();
            }
        }
 
        private void wavPlayer_LoadCompleted(object sender, AsyncCompletedEventArgs e)
        {
                ((System.Media.SoundPlayer)sender).Play();
        }
VB.NET
Private Sub btnPlay_Click(ByVal sender As Object, ByVal e As EventArgs)
      If txtFileNm.Text <> String.Empty Then
            Dim wavPlayer As SoundPlayer = New SoundPlayer()
            wavPlayer.SoundLocation = txtFileNm.Text
AddHandler wavPlayer.LoadCompleted, AddressOf wavPlayer_LoadCompleted
            wavPlayer.LoadAsync()
      End If
End Sub
 
Private Sub wavPlayer_LoadCompleted(ByVal sender As Object, ByVal e As AsyncCompletedEventArgs)
      CType(sender, System.Media.SoundPlayer).Play()
End Sub
