How I can get number of logical cores in CPU?
I need this to determine how many threads I should run in my application.
使用Environment.ProcessorCount属性 ,它返回逻辑核心数。
You can get number of logical processors through the Environment class
number of cores:
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);
number of logical processors
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);
}
}
