C＃.NET：如何检查，如果我们使用电池运行？ [英] C# .NET: How to check if we're running on battery?

问题描述

我想成为一个优秀的开发人员的公民，支付我的税，如果​​我们正在运行通过远程桌面，或电池运行禁用的事情。

i want to be a good developer citizen, pay my taxes, and disable things if we're running over Remote Desktop, or running on battery.

如果我们通过远程桌面在运行中（或等价终端服务器会话），我们必须禁用动画和双缓冲。你可以检查此：

If we're running over remote desktop (or equivalently in a Terminal server session), we must disable animations and double-buffering. You can check this with:

/// <summary>
/// Indicates if we're running in a remote desktop session.
/// If we are, then you MUST disable animations and double buffering i.e. Pay your taxes!
/// 
/// </summary>
/// <returns></returns>
public static Boolean IsRemoteSession
{
    //This is just a friendly wrapper around the built-in way
    get
    {
        return System.Windows.Forms.SystemInformation.TerminalServerSession;
    }
}

现在我需要找出如果用户正在运行电池供电。如果是这样，我不希望通过他们的电池吹。我想要做的事情，如

Now i need to find out if the user is running on battery power. If they are, i don't want to blow through their battery. i want to do things such as

• 禁用动画


• 禁用背景拼写检查


• 关闭后台打印


• 关闭梯度


• 使用 graphics.Smoothi​​ngMode = Smoothi​​ngMode.HighSpeed ;


• 使用 graphics.InterpolationMode = InterpolationMode.Low;


• 使用 graphics.CompositingQuality = CompositingQuality.HighSpeed​​;


• 最大限度地减少硬盘的使用 - 避免旋转加速


• 最小化网络接入 - 节省的WiFi功率

• disable animations
• disable background spell-checking
• disable background printing
• turn off gradients
• use graphics.SmoothingMode = SmoothingMode.HighSpeed;
• use graphics.InterpolationMode = InterpolationMode.Low;
• use graphics.CompositingQuality = CompositingQuality.HighSpeed;
• minimize hard drive access - to avoid spin up
• minimize network access - to save WiFi power

有没有一种管理方法，如果机器的目前电池运行？

Is there a managed way to see if the machine is currently running on battery?

推荐答案

我相信你可以检查<一HREF =htt​​p://msdn.microsoft.com/en-us/library/system.windows.forms.systeminformation.powerstatus%28VS.80%29.aspx> SystemInformation.PowerStatus 来看看它在电池或没有。

I believe you can check SystemInformation.PowerStatus to see if it's on battery or not.

Boolean isRunningOnBattery =
      (System.Windows.Forms.SystemInformation.PowerStatus.PowerLineStatus == 
       PowerLineStatus.Offline);

编辑：除上述外，还有一个System.Windows.Forms的PowerStatus 类。它的一个方法是 PowerLineStatus ，这将等于PowerLineStatus.Online如果它使用交流电源。

In addition to the above, there's also a System.Windows.Forms.PowerStatus class. One of its methods is PowerLineStatus, which will equal PowerLineStatus.Online if it's on AC Power.
