为什么我用wmi取得cpu的processorid时是空的

[sulong1234]

processorid是cpu唯一的序列号吗？？？
如果不是，那什么可以唯一的标志cpu?

我看其它的例程取的processorid也是空的

你CMD方式下直接使用wmic cpu list试试

[modena]

c:\>wmic
wmic:root\cli>cpu list

胡涂了,不知道两位在说啥了.
楼主的意思是要用API找CPU标识吧

因为楼主是使用wmi获取CPU ID的,所以我建议楼主使用wmi的命令行方式先看看本机的CPUID是否能正确获取:
C:\Documents and Settings\Administrator>wmic cpu get name,processorid
Name ProcessorId
Intel(R) Pentium(R) 4 CPU 2.80GHz BFEBFBFF00000F34
