vb.net 中的控制音量 [英] Control Volume in vb.net

问题描述

我需要在 vb.net 中控制主机音量.我在网上搜索并尝试了所有我能找到的例子.没有一个奏效.

I need to control the main computer volume in vb.net. I have searched the web and tried all the examples I could find. None of the have worked.

有没有人有一些与 vb.net 2010 一起使用来控制音量的代码片段?

Does anyone have some snippets of code that work with vb.net 2010 to control volume?

谢谢

推荐答案

我找到了答案.它使用 Nirsoft 的 NirCmd(32 位、64 位)

I found an answer. Its uses Nirsoft's NirCmd (32-bit , 64-bit)

Public Class Sound
    Dim nircmd As String
    Const MAXVOL As Integer = 65535

    Public Sub New(ByVal nircmd_location As String)
        nircmd = nircmd_location
    End Sub

    Public Sub setVol(ByVal level As Integer)

        Dim p As New ProcessStartInfo
        p.FileName = nircmd
        p.Arguments = "setsysvolume " & (MAXVOL * (level / 100)).ToString
        Process.Start(p)

    End Sub
End Class

然后你可以使用类似的东西

You can then use somthing like

Dim vol As New Sound(path_to_nircmd)
vol.setVol(50)
