在開發程式時，有時需要知道部份的硬體資訊等，像是ProcessId的編號、System Name等，可以利用System Manager的查詢來取得其內容。底下是可查詢到的資料

ProcessId的序號並非唯一而且一定取的到的，如果需要唯一值，建議可以使用Mac Address會比較好。
在使用時System.Manager需要被參考
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Management;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
try
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select * From Win32_Processor");
foreach (ManagementObject managementObject in searcher.Get())
{
foreach (PropertyData property in managementObject.Properties)
{
if (property.Value == null)
continue;
if (property.Name.ToLower() == "ProcessorId".ToLower())
Console.WriteLine("Processor序號:"+property.Value.ToString());
else
Console.WriteLine(property.Name+":"+property.Value.ToString());
}
}
}
catch (Exception ex)
{
Console.Write(ex);
}
Console.Read();
}
}
}
取得Mac Address
string mac= "";
NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
//for each j you can get the MAC ,nics[0]第一張網卡,1則為第二張網卡
PhysicalAddress address = nics[0].GetPhysicalAddress();
byte[] bytes = address.GetAddressBytes();
for (int i = 0; i < bytes.Length; i++)
{
// Display the physical address in hexadecimal.
mac+=bytes[i].ToString("X2");
// Insert a hyphen after each byte, unless we are at the end of the
// address.
if (i != bytes.Length - 1)
{
mac+= ("-");
}
}
Console.WriteLine(mac);
