C#精髓
第二講 WMI完美秀出CPU編號廠商主頻電壓等全部資訊
作者:清清月兒
關於WMI MSDN有詳細說明。 本文列舉數例算拋磚引玉吧。WMI是個好東西,看過本文後也許你應該能舉一反三參考MSDN也許自己做個優化大師也是可能的。
本文的例子在以下環境除錯通過:Windows2003+AMD64雙核CPU+VisualStudio2005(C#)下除錯通過,無錯版!
首先要新增“引用”一個dll,選擇“System Management”;
再引入2個名稱空間:using System.Management;using System.IO;
foreach迴圈:宣告一個迭代變數自動獲取陣列中每個元素的值。String.Format:格式化字元,本站就有解釋。
程式碼:
