如何在C#中获取CPU的逻辑内核/线程数？

Question

如何在CPU中获得多个逻辑核心？

我需要这个来确定我应该在我的应用程序中运行多少个线程.

Answer 1

使用Environment.ProcessorCount属性,它返回逻辑核心数.

Answer 2

您可以通过Environment类
核心数获取多个逻辑处理器:

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);

逻辑处理器的数量

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);
     }
 }
