vb.net 中 如何實現(xiàn) 播放mp3文件

在.NET里，沒有托管的音樂播放器，用API只能播放WAV格式，對于MP3等形式的音頻文件，就要依賴于其他控件了，常用的就是

MediaPlayer。使用方法：

在工具箱上點右鍵，選擇“選擇項目(Choose

Items)”，切到COM選項卡，找到

Windows

Media

Player，

勾選，確定

在t工具箱上，把剛才加入的MediaPlayer控件，拖放到窗體上

代碼：

WindowsMediaPlayer1.URL

=

"mp3文件路徑，支持網(wǎng)絡(luò)路徑"

WindowsMediaPlayer1.Ctlcontrols.play

基本就OK了，至于其他的操作諸如下一曲上一曲暫停停止，直接看

WindowsMediaPlayer1.Ctlcontrols.

里面的方法吧。

VB.NET中播放背景音樂最簡單的辦法是什么啊?

給你我的程序，自己研究一下吧，我也不是很明白。

Public Class Form1

Private Declare Auto Function PlaySound Lib "winmm.dll" (ByVal lpszSoundName As String, ByVal hModule As Integer, ByVal dwFlags As Integer) As Integer

Const SND_filename As Integer = H20000

Const SND_alias As Integer = H10000

Const SND_sync As Integer = H0

Declare Auto Function waveOutGetNumDevs Lib "winmm.dll" Alias "waveOutGetNumDevs" () As Integer

Declare Auto Function sndPlaySound Lib "winmm.dll" (ByVal filename As String, ByVal options As Integer) As Integer

Private Const SND_memory As Integer = H4

Private Const SND_async As Integer = H1

Private Const proess_domain As String = ""

Const SND_sync1 = H0

Const SND_async1 = H1

Const SND_nodefault = H2

Const SND_loop = H8

Const SND_nostop = H10

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Beep()

End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

Dim strFileName As String = "start.wav"

PlaySound(strFileName, 0, SND_filename)

End Sub

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click

PlaySound("systemstart", 0, SND_alias Or SND_sync)

End Sub

Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click

Dim ret As Long

Dim strfilename As String

strfilename = "start.wav"

ret = sndPlaySound(strfilename.ToCharArray, 0)

End Sub

Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click

Dim i As Integer

i = waveOutGetNumDevs()

If i 0 Then

MsgBox("可以播放聲音", 64, "檢測")

Else

MsgBox("不能播放聲音", 64, "檢測")

End If

End Sub

End Class

vb.net中如何播放聲音，是要什么控件嘛？

My.Computer.Audio.Play("SoundFile.wav")

SoundFile.wav是你要播放的聲音文件的路徑
