Question

我在Visual Studio 2013中使用VB创建了一个简单的媒体播放器。我的要求是：只需按一个按钮，我就需要播放固定路径下可用的视频文件（使用我修复的OpenFileDialog路径）。例如。按下名为“A”的按钮应播放“C：/播放列表”

中的文件

如何做到这一点？如果需要，我可以分享我当前的代码。我是VB的新手。

代码：

Public Class Form1

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    With OpenFileDialog1
        .Filter = "MPEG-4|*.mp4"
        .ShowDialog()
        TextBox1.Text = .FileName
    End With
    AxWindowsMediaPlayer1.URL = (OpenFileDialog1.FileName)
End Sub

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
    AxWindowsMediaPlayer1.Ctlcontrols.play()
End Sub

Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click
    AxWindowsMediaPlayer1.Ctlcontrols.pause()
End Sub

Private Sub Button4_Click(sender As Object, e As EventArgs) Handles Button4.Click
    AxWindowsMediaPlayer1.Ctlcontrols.stop()
End Sub

Private Sub TrackBar1_Scroll(sender As Object, e As EventArgs) Handles TrackBar1.Scroll
    AxWindowsMediaPlayer1.settings.volume = TrackBar1.Value
End Sub

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    AxWindowsMediaPlayer1.settings.volume = 20
End Sub

End Class

我需要一个名为A，B，C等的按钮，比如播放，暂停，我已经拥有。按下按钮A应该从'C：\ Playlist'中播放'file_A.mp3'

Answer 1

AxWindowsMediaPlayer1.URL = "C:\Playlist\file_A.mp3"
AxWindowsMediaPlayer1.Ctlcontrols.play()

在Visual Studio 2013中，按钮是否可以硬编码以播放来自已知路径的视频？
