再 using
using System.Management;
using System.Management.Instrumentation;
using System.Diagnostics;
using System.Threading;
namespace ButterMain
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
Thread bty;
private void Battery()
{
ManagementClass mc = new ManagementClass("Win32_Battery");
ManagementObjectCollection moc = mc.GetInstances();
ManagementObjectCollection.ManagementObjectEnumerator mom =
moc.GetEnumerator();
if (mom.MoveNext())
{
if
(mom.Current.Properties["EstimatedChargeRemaining"].Value.ToString() == "100")
{
this.lb_12.Text = "使用交流電";
}
else
{
this.lb_12.Text =
mom.Current.Properties["EstimatedChargeRemaining"].Value.ToString() + "%";
//電池電量
}
}
else
{
this.lb_12.Text = "未知的狀態";
}
}
private void Form1_Load(object sender, EventArgs e)
{
CheckForIllegalCrossThreadCalls = true ;
Battery();
}
private void timer1_Tick(object sender, EventArgs e)
{
bty = new Thread(new ThreadStart(Battery));
bty.Start();//Time控件
}
}
}
