C#取CPU核心数的算法

 ManagementObjectSearcher searcher = new ManagementObjectSearcher("select * from Win32_Processor");

            int count = 0;//核心数

            foreach (ManagementObject obj in searcher.Get())

            {

                object cores = obj["NumberOfCores"];

                if (cores == null)

                {

                    break;

                }

                string numberOfCores = obj["NumberOfCores"].ToString();

                int coreCount;

                bool success = int.TryParse(numberOfCores, out coreCount);

                if (success)

                {

                    count ++;

                }

            }
