C＃设置屏幕亮度的Windows 7 [英] C# setting screen brightness Windows 7

问题描述

我想通过我的自我ajust屏幕亮度。因为Windows让我只能调整幅度有限。我想调暗显示，从0到100％，将其关闭/开启。它应该是可能的，如果窗口可以自动做（DIM后显示：X分钟/关闭显示器后X分钟）。我尝试了一些源和类我由谷歌找到。但是，没有他们的工作。

I want ajust screen brightness by my self. Because Windows lets me only adjusting in limited range. I want dim the display from 0 to 100% and turning it off/on. It should be possible if windows can it do automatically (Dim display after: x minutes/Turn off display after: x minutes). I tried some sources and classes what I found by google. But no of them works.

你有没有试过这种，或者你可以推荐我的任何工作code？

Have you ever tried this or can you recommend me any working code?

感谢响应。

推荐答案

您可以使用 WmiSetBrightness 方法：

using System.Management;
//...
static void SetBrightness(byte targetBrightness) {
    ManagementScope scope = new ManagementScope("root\\WMI");
    SelectQuery query = new SelectQuery("WmiMonitorBrightnessMethods");
    using(ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query)) {
        using(ManagementObjectCollection objectCollection = searcher.Get()) {
            foreach(ManagementObject mObj in objectCollection) {
                mObj.InvokeMethod("WmiSetBrightness",
                    new Object[] { UInt32.MaxValue, targetBrightness });
                break;
            }
        }
    }
}
