有没有在c#中生成一个唯一的机器哈希

using System.Management;

public static string GetMachineHash()
{
    string machineHash = string.Empty;

    try
    {
        ManagementClass managementClass = new ManagementClass("Win32_ComputerSystemProduct");
        ManagementObjectCollection managementObjects = managementClass.GetInstances();

        foreach (ManagementObject managementObject in managementObjects)
        {
            machineHash = managementObject.Properties["UUID"].Value.ToString();
            break;
        }
    }
    catch (Exception ex)
    {
        // 处理异常
    }

    return machineHash;
}

using System.Security.Cryptography;
using System.Text;

public static string GetMachineHash()
{
    string machineHash = string.Empty;

    try
    {
        using (MD5 md5 = MD5.Create())
        {
            string machineIdentifier = GetMachineIdentifier(); // 获取机器的唯一标识符
            byte[] hashBytes = md5.ComputeHash(Encoding.UTF8.GetBytes(machineIdentifier));

            StringBuilder stringBuilder = new StringBuilder();
            for (int i = 0; i < hashBytes.Length; i++)
            {
                stringBuilder.Append(hashBytes[i].ToString("x2"));
            }

            machineHash = stringBuilder.ToString();
        }
    }
    catch (Exception ex)
    {
        // 处理异常
    }

    return machineHash;
}

private static string GetMachineIdentifier()
{
    // 返回机器的唯一标识符，可以根据需求自定义实现
    return Environment.MachineName;
