用.NET语言写一个获取硬盘序列号、CPU序列号和主板序列号的类

您可以使用以下代码获取硬盘序列号、CPU序列号和主板序列号：

using System.Management;

public class SystemInfo
{
    // 获取硬盘序列号
    public static string GetHddSerialNumber()
    {
        ManagementObjectSearcher searcher =
            new ManagementObjectSearcher("SELECT SerialNumber FROM Win32_DiskDrive");
        foreach (ManagementObject wmi_HD in searcher.Get())
        {
            string serial = wmi_HD["SerialNumber"].ToString().Trim();
            return serial;
        }
        return null;
    }

    // 获取CPU序列号
    public static string GetCpuSerialNumber()
    {
        ManagementObjectSearcher searcher =
            new ManagementObjectSearcher("SELECT ProcessorId FROM Win32_Processor");
        foreach (ManagementObject wmi_CPU in searcher.Get())
        {
            string serial = wmi_CPU["ProcessorId"].ToString().Trim();
            return serial;
        }
        return null;
    }

    // 获取主板序列号
    public static string GetBoardSerialNumber()
    {
        ManagementObjectSearcher searcher =
            new ManagementObjectSearcher("SELECT SerialNumber FROM Win32_BaseBoard");
        foreach (ManagementObject wmi_Board in searcher.Get())
        {
            string serial = wmi_Board["SerialNumber"].ToString().Trim();
            return serial;
        }
        return null;
    }

}

使用方法如下：

string hddSerial = SystemInfo.GetHddSerialNumber();
string cpuSerial = SystemInfo.GetCpuSerialNumber();
string boardSerial = SystemInfo.GetBoardSerialNumber();

请注意，该代码需要运行在拥有 Administrator 权限的用户下。
