在裝置(mobile)播放mp3檔案

Note：本篇開發端Media Player版本為11， WM6上Media版本為10.3
之前在"如何讓裝置發出聲音"這篇，我們有談過利用呼叫API的方式來播放wav檔，那如果要播放mp3那要怎麼做呢？
首先下面有一些參考資料

• play .wma and .mp3 in windows mobile 5
• .NET CF 2 - how to play video?

下面是測試的程式碼，可以參考看看
畫面上有一個ListBox名稱為ListBox1，兩個Button分別為btnStart、btnStop

Public Class Form1

    Dim Player As WMPLib.WindowsMediaPlayer

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        For Each s As String In IO.Directory.GetFiles("\儲存卡\Music")
            ListBox1.Items.Add(s)
        Next
        Player = New WMPLib.WindowsMediaPlayer
        Player.settings.volume = 10
    End Sub

    Private Sub btnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.Click
        If ListBox1.SelectedIndex >= 0 Then
            Player.URL = ListBox1.SelectedItem
            Player.controls.play()
        End If
    End Sub

    Private Sub btnStop_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStop.Click
        Player.controls.stop()
    End Sub
End Class
