vb.net - 单击后如何更改图像按钮的图像？

Question

我正在尝试更改我的 Bunifu 图像按钮的图像，因为它是一个音量开/关按钮。但是我的代码有一个例外，上面写着“路径不是合法形式”。

这是我的代码：

Private Sub BtnMute_Click(sender As Object, e As EventArgs) Handles BtnMute.Click

    Dim OpenFileDialog As New OpenFileDialog
    Dim Filename = "D:\Storage\Team Tag\Corporation\Corporation 3D Logo (PNG).png"

    Dim mute As New System.Drawing.Bitmap(OpenFileDialog.FileName)

    If MissionBriefingPlayer.settings.volume > 0 Then
        MissionBriefingPlayer.settings.volume = 0
        BtnMute.Image = mute
    Else
        MissionBriefingPlayer.settings.volume = 100
    End If

End Sub

Answer 1

OpenFileDialog不需要。

这里有一个更好的方法。此外，您可以做的另一件事是，在取消静音时不要将音量设置为 100，而是在静音之前将音量保存在静态变量中，然后在取消静音时将其设置回保存的音量：

Private Sub BtnMute_Click(sender As Object, e As EventArgs) Handles BtnMute.Click

    Static _savedVolume as Integer = 0

    If MissionBriefingPlayer.settings.volume > 0 Then
        _savedVolume = MissionBriefingPlayer.settings.volume

        MissionBriefingPlayer.settings.volume = 0

        BtnMute.Image = New System.Drawing.Bitmap("D:\Storage\Team Tag\Corporation\Corporation 3D Logo (PNG).png")
    Else
        MissionBriefingPlayer.settings.volume = _savedVolume
    End If

End Sub
