如何从WPF applicatioin使用WMI让电池充电状态? [英] How to get Battery charging status from WPF applicatioin using WMI?
问题描述
我试图让充电%,而正是在Windows显示相同的文字 - 不充电,充满电,充电
I'm trying to get charging percent, and exactly the same text that is Windows showing - Not Charging, Full Charged, Charging
我使用WMI查询。
我不想硬code的文本,因为它每一次的工作不同。 有时,它显示95百分比不充电,也可以充电。
I don't want to hard-code that texts, because it's working differently every time. Sometimes it's showing 95 percent- Not Charging, or can be Charging.
有没有办法得到这一结果的文本?
Is there any way to get that result text?
我能做些什么,只是为了检查,如果它是100%的充电,显示充满电。
What I can do, just to check if it is 100 percent charged, to display Full Charged.
但对于96%,这是不同的工作,有时Windows显示带电或不充电
But for 96 percent, it is working differently, sometimes Windows display Charged, or Not Charging
推荐答案
使用的 Win32_Battery 类:
static string GetBatteryStatus() {
ManagementScope scope = new ManagementScope("//./root/cimv2");
SelectQuery query = new SelectQuery("Select BatteryStatus From Win32_Battery");
using(ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query)) {
using(ManagementObjectCollection objectCollection = searcher.Get()) {
foreach(ManagementObject mObj in objectCollection) {
PropertyData pData = mObj.Properties["BatteryStatus"];
switch((Int16)pData.Value) {
//...
case 2:return "Not Charging";
case 3:return "Fully Charged";
case 4:return "Low";
case 5: return "Critical";
//...
}
}
}
}
return string.Empty;
}
