主音量是静音还是静音？！ [英] Master volume is mute or is unmute?!

问题描述

如何在C＃编程中检查主音量是静音还是静音？

我有这段代码：

How i can check master volume is mute or is unmute in C# programming??
I have this code:

private const int APPCOMMAND_VOLUME_MUTE = 0x80000;
private const int WM_APPCOMMAND = 0x319;
[DllImport("user32.dll")]
public static extern IntPtr SendMessageW(IntPtr hWnd, int Msg, IntPtr wParam,IntPtr lParam);

但它没有给我音量状态。这段代码只是改变状态。

Tnx

but it does not give me volume status. this code just change the status.
Tnx

推荐答案

你可以使用

来完成一些复杂的代码

You can do it with some complicated code using

[DllImport("winmm.dll")]
public static extern int mixerGetControlDetails(IntPtr hmxobj,ref MIXERCONTROLDETAILS pmxcd, MIXER_GETCONTROLDETAILSFLAG fdwDetailsmixer);

最佳选择是获取Gustavo Franco的WaveLibMixer代码，例如来自
