怎么使用C++或C#获取计算机CPU的序列号(唯

第一步，创建性能监视器对象：
PerformanceCounter _oPerformanceCounter=new PerformanceCounter("Processor","% Processor Time","_Total");
第二步，获取CPU使用情况：
float _nVal=_oPerformanceCounter.NextValue();
_nVal中就是当前CPU的使用率了，加上百分号(%)就是使用率的百分比，比如：
string _s="当前CPU使用率：" + nVal.ToString("0.0") + "%";

Process [] pro;
pro = Process.GetProcesses();
int total=0;
Process temp;
int i;
for(i=0;i<pro.Length ;i++)
{
temp =pro[i];
total=temp.PrivateMemorySize +total ;
}

获得内存的占用大小

//cpu频率

using Microsoft.Win32;

private int GetCPUFrequency()
{
RegistryKey rk = Registry.LocalMachine.OpenSubKey(@"HARDWARE\DESCRIPTION\System\CentralProcessor\0");

object obj = rk.GetValue("~MHz");
int CPUFrequency = (int)obj;
return CPUFrequency;
}

using System.Management;

disk.Get();
string totalByte = disk["FreeSpace"].ToString();
long freeDiskSpaceMb = Convert.ToInt64(totalbyte)/1024/1024;
return freeDiskSpaceMb;
}

} 嘿嘿

这个没有。。。有的话还有隐私吗？

网卡还有序列号？有Mac地址吧？

　　c#获取计算机任务管理器中进程对应的线程数量的方法
打开任务管理器， 查看---选择列----线程数 勾起来后，就可以查看到每个程序的线程数了。
或者
using System.Diagnostics;
Process.GetCurrentProcess().Threads.Count;
可获取到线程的数量。
获取正在使用的线程数量：
int n = 0;
foreach (ProcessThread th in Process.GetCurrentProcess().Threads)
{
if (th.ThreadState == ThreadState.Running)
{
n++;
}
}

去工作管理员看看
