C #, use the WMI Object to get the percentage of remaining power of the notebook battery

Sometimes you need to monitor the remaining power of the notebook battery. After investigation, you can find that the WMI object can be done.
Before using the WMI object, you must add a reference to System. Management, and then you can call the WMI Object.
The WMI object we use is: Win32_Battery
Object Reference: http://msdn.microsoft.com/zh-cn/library/aa394074 (v = VS.85). aspx
Code:
ManagementClass mc = new ManagementClass ("Win32_Battery ");
ManagementObjectCollection moc = mc. GetInstances ();

ManagementObjectCollection. ManagementObjectEnumerator mom = moc. GetEnumerator ();
If (mom. MoveNext ()){
Console. WriteLine ("EstimatedChargeRemaining: \ t {0 }%", mom. Current. Properties [" EstimatedChargeRemaining "]. Value );
}

Development Environment: VS2010,. Net FrameWork4.0
The Code passes the test in Win7.
