很簡單的一個需求，在CMD下我們可以使用systeminfo命令來獲取相關資訊。當然我們也可以使用PROCESS來執行這個命令並重定向資料進一步分析製造商。但相對來說速度較慢。

下面程式碼使用WMI來獲取資訊

using System;
using System.Management;
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            // create management class object
            ManagementClass mc = new ManagementClass("Win32_ComputerSystem");
            //collection to store all management objects
            ManagementObjectCollection moc = mc.GetInstances();
            if (moc.Count != 0)
            {
                foreach (ManagementObject mo in mc.GetInstances())
                {
                    // display general system information
                    Console.WriteLine("\nMachine Make: {0}",
                                      mo["Manufacturer"].ToString());
                }
            }
            //wait for user action
            Console.ReadLine();
        }
    }
}
