C#获取CPU编号

[cuifengyin3044]

我想获取CPU编号 方法是这样的:

/// <summary>
/// 获取CPU
/// </summary>
/// <returns></returns>
public string getCPUID()
{
string cpuInfo = "";//cpu序列号
ManagementClass cimobject = new ManagementClass("Win32_Processor");
ManagementObjectCollection moc = cimobject.GetInstances();
foreach (ManagementObject mo in moc)
{
cpuInfo = mo.Properties["ProcessorId"].Value.ToString();
}
return cpuInfo;
}
为什么在不同电脑上，获取到得CPU编号是一样的。。。CPU应该不是一样的.这个方法是不是不正确。。
这个方法获取到得值是32位的，而我下了一个获取CPU编号的软件获取到得是64位的 谁能帮我解决下。。谢谢了！急!

给以一段源码，获取cpu号的方法，直接调用

/// <summary>
        /// 获得CUP编号
        /// </summary>
        /// <returns>获得CUP编号</returns>
        public String GetCpuID()
        {
            try
            {
                ManagementClass mc = new ManagementClass("Win32_Processor");
                ManagementObjectCollection moc = mc.GetInstances();

                String strCpuID = null;
                foreach (ManagementObject mo in moc)
                {
                    strCpuID = mo.Properties["ProcessorId"].Value.ToString();
                    break;
                }
                return strCpuID;
            }
            catch
            {
                return "";
            }

        }

试试看啦，我是可以用的

提醒LZ: CPU 是没有唯一序列号的!!!!除了Ｎ年前的奔３,
还有硬盘也是,现在大多是 SATA 硬盘,也是没有唯一序列号的,(IDE硬盘有)
所以如果LZ是想确定电脑的唯一性的话 , 最好是打网卡物理地址和主板的主意(但非品牌机的主板好象很多也没有唯一性)

using System.Management;
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";

为什么在不同电脑上，获取到得CPU编号是一样的？

现很多时候相同的CPU你得到的是相同的型号，CPU ID 现在不像以前那样是唯一的了。 你还是用网卡的 Mac 地址吧。下面是 Mac 地址的代码

建议使用硬盘序列号作为唯一标识

[henyzhang]

之前我也需要用到过这种功能，后来网上下载了一段代码解决的。

[cnwin]

取多个硬件的序列号组合一下更好.
