C# code
Double CPUtprt = 0;

System.Management.ManagementObjectSearcher mos = new System.Management.ManagementObjectSearcher(@"root\WMI", "Select * From MSAcpi_ThermalZoneTemperature");

foreach (System.Management.ManagementObject mo in mos.Get())

{

     CPUtprt = Convert.ToDouble(Convert.ToDouble(mo.GetPropertyValue("CurrentTemperature").ToString()) - 2732) / 10;

textBox1.Text = ("CPU 溫度 : " + CPUtprt.ToString() + " °C");

}

探讨

C# code
Double CPUtprt = 0;

System.Management.ManagementObjectSearcher mos = new System.Management.ManagementObjectSearcher(@"root\WMI", "Select * From MSAcpi_ThermalZoneTemperature");

CPU温度也能这样知道，呵呵，学习了

引用System.Management

加入如下代码：
Double CPUtprt = 0;
System.Management.ManagementObjectSearcher mos = new System.Management.ManagementObjectSearcher(@"root\WMI", "Select * From MSAcpi_ThermalZoneTemperature");
foreach (System.Management.ManagementObject mo in mos.Get())
{
   CPUtprt = Convert.ToDouble(Convert.ToDouble(mo.GetPropertyValue("CurrentTemperature").ToString()) - 2732) / 10;
   this.textBox1 .Text = ("CPU 溫度 : " + CPUtprt.ToString() + " °C");
}

这个需要主板的接口吧，应该是主板的功能。
