如何获得cpu中的逻辑内核数？
我需要这个来确定我应用程序中应该运行多少个线程.
解决方法
您可以通过Environment类获得多个逻辑处理器
核心数：
核心数：
int coreCount = 0;
foreach (var item in new System.Management.ManagementObjectSearcher("Select * from Win32_Processor").Get())
{
coreCount += int.Parse(item["NumberOfCores"].ToString());
}
Console.WriteLine("Number Of Cores: {0}",coreCount);
逻辑处理器数量
foreach (var item in new System.Management.ManagementObjectSearcher("Select * from Win32_ComputerSystem").Get())
{
Console.WriteLine("Number Of Logical Processors: {0}",item["NumberOfLogicalProcessors"]);
}
Environment.ProcessorCount
using System;
class Sample
{
public static void Main()
{
Console.WriteLine("The number of processors on this computer is {0}.",Environment.ProcessorCount);
}
}
