    第二讲 WMI完美秀出CPU编号厂商主频电压等全部信息

    作者:清清月儿

    关于WMI MSDN有详细说明。 本文列举数例算抛砖引玉吧。WMI是个好东西,看过本文后也许你应该能举一反三参考MSDN也许自己做个优化大师也是可能的。

    本文的例子在以下环境调试通过:Windows2003+AMD64双核CPU+VisualStudio2005(C#)下调试通过,无错版

     

    首先要添加“引用”一个dll,选择“System Management”;

    再引入2个命名空间:using  System.Management;using  System.IO;

    foreach循环:声明一个迭代变量自动获取数组中每个元素的值。String.Format:格式化字符,本站就有解释。

     

    代码:
