如何获取 CPU 中的逻辑核心数?
我需要这个来确定我应该在我的应用程序中运行多少线程。
使用Environment.ProcessorCount 属性,它返回逻辑核心的数量。
您可以通过 Environment class
number of cores 获取逻辑处理器的数量:
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);
}
}
