C# 获取MAC地址
/*********************************************************************** C# 获取MAC地址
* 说明：
* 在C#中获取本机的MAC地址，文中提供两个参考，一个是能够所有的MAC
* 地址，一个是获取第一个MAC地址。

一、参考文档：
1. Reliable method to get machine's MAC address in C#
http://stackoverflow.com/questions/850650/reliable-method-to-get-machines-mac-address-in-c-sharp
二、解决方法：
using System;
using System.Collections.Generic;
using System.Text;
using System.Net.NetworkInformation;
namespace LocalDetectTest
{
class NetTools
{
/// <summary>
/// Finds the MAC address of the NIC with maximum speed.
/// </summary>
/// <returns>The MAC address.</returns>
public static void PrintAllMacAddress()
{
const int MIN_MAC_ADDR_LENGTH = 12;
string macAddress = string.Empty;
long maxSpeed = -1;
foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
{
Console.WriteLine(
"Name: " + nic.Name +
" Found MAC Address: " + nic.GetPhysicalAddress() +
" Type: " + nic.NetworkInterfaceType);
string tempMac = nic.GetPhysicalAddress().ToString();
if (nic.Speed > maxSpeed &&
!string.IsNullOrEmpty(tempMac) &&
tempMac.Length >= MIN_MAC_ADDR_LENGTH)
{
Console.WriteLine("New Max Speed = " + nic.Speed + ", MAC: " + tempMac);
maxSpeed = nic.Speed;
macAddress = tempMac;
}
}
// return macAddress;
}
/// <summary>
/// Finds the MAC address of the first operation NIC found.
/// </summary>
/// <returns>The MAC address.</returns>
public static string GetFirstMacAddress()
{
string macAddresses = string.Empty;
foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
{
if (nic.OperationalStatus == OperationalStatus.Up)
{
macAddresses += nic.GetPhysicalAddress().ToString();
Console.WriteLine(macAddresses);
break;
}
}
return macAddresses;
}
}
}
