上面那个有问题，网卡或者ip变了，会生成新的机器码，所以，换下面这个吧

public class SoftReg
{
/// <summary>
/// 获取设备硬件码
/// </summary>
/// <returns></returns>
public static string Token()
{
string HDid = GetHDid();
//string mac=GetMoAddress();
string cpu = GetCpuID();
//应该总有一个能获取到吧！！
if (HDid != null || cpu != null)
{
string temp = HDid + cpu;
return GetMD5String(temp);
}
else {
return null;
}
}
public static string GetCpuID()
{
try
{
//获取CPU序列号代码
string cpuInfo = "";//cpu序列号
ManagementClass mc = new ManagementClass("Win32_Processor");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject mo in moc)
{
cpuInfo = mo.Properties["ProcessorId"].Value.ToString();
}
moc = null;
mc = null;
return cpuInfo;
}
catch
{
return "unknow";
}
}
/// <summary>
/// 获取硬盘ID
/// </summary>
/// <returns> string </returns>
public static string GetHDid()
{
try
{
string HDid = null;
using (ManagementClass cimobject1 = new ManagementClass("Win32_DiskDrive"))
{
ManagementObjectCollection moc1 = cimobject1.GetInstances();
foreach (ManagementObject mo in moc1)
{
HDid = (string)mo.Properties["Model"].Value;
mo.Dispose();
}
}
return HDid;
}
catch (Exception ex)
{
return null;
}
}
/// <summary>
/// 获取网卡硬件地址
/// </summary>
/// <returns> string </returns>
public static string GetMoAddress()
{
try
{
string MoAddress = null;
using (ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"))
{
ManagementObjectCollection moc2 = mc.GetInstances();
foreach (ManagementObject mo in moc2)
{
if ((bool)mo["IPEnabled"] == true)
MoAddress = mo["MacAddress"].ToString();
mo.Dispose();
}
}
return MoAddress;
}
catch (Exception ex)
{
return null;
}
}
/// <summary>
/// 通过字符串获取MD5值，返回32位字符串。
/// </summary>
/// <param name="str"></param>
/// <returns></returns>
public static string GetMD5String(string text)
{
MD5CryptoServiceProvider md5Hasher = new MD5CryptoServiceProvider();
byte[] data = md5Hasher.ComputeHash(Encoding.Default.GetBytes(text));
StringBuilder sBuilder = new StringBuilder();
for (int i = 0; i < data.Length; i++)
{
sBuilder.Append(data[i].ToString("x2"));
}
return sBuilder.ToString().ToLower();
}
}

在获取硬盘Id的时候，还是有问题

如果，插入一个u盘，就会导致，获取的机器码不正确，下面的代码凑合着用吧

不获取带usb的硬盘id

应该是比较完美的解决方案如下：
