C#获取CPU编号
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!

试试看啦，我是可以用的 --------------------编程问答-------------------- 顶顶顶 --------------------编程问答--------------------

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

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) --------------------编程问答-------------------- using System.Management;
