實現效果
- 本輔助類主要是用來方便實現獲取用戶硬件的相關信息，根據用戶各種硬件（CPU、網卡、磁盤、主板等）標識信息，獲取一個8位唯一標識數字。
- 本輔助類只提供了一個公共的方法Value，它集合了CPU、網卡、磁盤、主板等信息，通過這個8位的數字標識，我們可以唯一區分一臺電腦，類似我們每個人的指紋信息一樣，很少會發生重複的現象，可以用在一些關鍵的註冊授權機制上。
實現步驟
/// 根據用戶各種硬件（CPU、網卡、磁盤、主板等）標識信息，獲取一個8位唯一標識數字
public static string Value()
/// 獲取硬件的標識信息
private static string identifier(string wmiClass, string wmiProperty, string wmiMustBeTrue)
/// 獲取硬件的標識信息
private static string identifier(string wmiClass, string wmiProperty)
/// 獲取CPU信息
private static string cpuId()
/// 獲取BOIS主板標識信息
private static string biosId()
/// 獲取主硬盤的標識信息
private static string diskId()
/// 獲取主板的標識信息
private static string baseId()
/// 獲取主視頻控制器標識信息
private static string videoId()
/// 獲取第一個可用網卡信息
private static string macId()
/// 轉換內容爲8位數字
private static string pack(string text)
- 輔助類HardwareHelper的使用例子代碼如下所示
string identity = HardwareHelper.Value();
MessageUtil.ShowTips(identity);
