1、 SendArp 获取MAC地址
SendARP函数用来发送ARP数据包并在定义的MAC缓冲区中返回定义的IP对应的MAC地址
SendARP(
IPAddr DestIP,
IPAddr SrcIP,
PULONG pMacAddr,
PULONG PhyAddrLen
);
第一个参数是IP地址的网络字节顺序，而不是一个指针，当初我就是赋值成指针而使得获取不了MAC地址。
第二个参数填0就可以
第三个参数是MAC缓冲区指针
第四个参数是一个指向一个DWORD型数值为6的指针
代码如下：
[DllImport("Iphlpapi.dll")]
static extern int SendARP(Int32 DestIP, Int32 SrcIP, ref Int64 MacAddr, ref Int32 PhyAddrLen);
/// <summary>
/// SendArp获取MAC地址
/// </summary>
/// <returns></returns>
public string GetMacAddressBySendARP()
{
StringBuilder strReturn = new StringBuilder();
try
{
System.Net.IPHostEntry Tempaddr = (System.Net.IPHostEntry)Dns.GetHostByName(Dns.GetHostName());
System.Net.IPAddress[] TempAd = Tempaddr.AddressList;
Int32 remote = (int)TempAd[0].Address;
Int64 macinfo = new Int64();
Int32 length = 6;
SendARP(remote, 0, ref macinfo, ref length);
string temp = System.Convert.ToString(macinfo, 16).PadLeft(12, '0').ToUpper();
int x = 12;
for (int i = 0; i < 6; i++)
{
if (i == 5) { strReturn.Append(temp.Substring(x - 2, 2)); }
else { strReturn.Append(temp.Substring(x - 2, 2) + ":"); }
x -= 2;
}
return strReturn.ToString();
}
catch
{
return "";
}
}
2、通过适配器信息获取MAC地址
iphlpapi.dll是Windows IP辅助API应用程序接口模块。其中一个函数GetAdaptersAddresses：返回和适配器关联的地址
uint GetAdaptersAddresses(uint Family, uint flags, IntPtr Reserved,
IntPtr PAdaptersAddresses, ref uint pOutBufLen);
Family：[输入]获得地址族，必须是以下值之一：
AF_INET (仅返回IPv4地址)，
AF_INET6（仅返回IPv6地址），
AF_UNSPEC（从所有的地址族返回地址）
Flags：[输入]返回地址类型，这个参数为0或是以下值的联合值：
GAA_FLAG_INCLUDE_PREFIX （返回IPv6地址前缀）
GAA_FLAG_SKIP_UNICAST（不返回unicast地址）
GAA_FLAG_SKIP_ANYCAST（不返回anycast地址）
GAA_FLAG_SKIP_FRIENDLY_NAME（不返回适配器的友好名称）
GAA_FLAG_SKIP_MULTICAST （不返回多点传送（multicast）地址）
GAA_FLAG_SKIP_DNS_SERVER （不返回DNS服务器地址）
Reserved：调用程序必须将此参数置为NULL
pAdapterAddresses：[输入，输出] 指向一段IP_ADAPTER_ADDRESSES缓存，成功的话，该缓存包含地址信息。
pOutBufLen：[输出] 返回pAdapterAddresses所在缓存的大小
返回值：成功，返回0；失败，返回错误代码。
代码如下：
[DllImport("Iphlpapi.dll")]
public static extern uint GetAdaptersAddresses(uint Family, uint flags, IntPtr Reserved,
IntPtr PAdaptersAddresses, ref uint pOutBufLen);
/// <summary>
/// 通过适配器信息获取MAC地址
/// </summary>
/// <returns></returns>
public string GetMacAddressByAdapter()
{
string macAddress = "";
try
{
IntPtr PAdaptersAddresses = new IntPtr();
uint pOutLen = 100;
PAdaptersAddresses = Marshal.AllocHGlobal(100);
uint ret =
GetAdaptersAddresses(0, 0, (IntPtr)0, PAdaptersAddresses, ref pOutLen);
if (ret == 111)
{
Marshal.FreeHGlobal(PAdaptersAddresses);
PAdaptersAddresses = Marshal.AllocHGlobal((int)pOutLen);
ret = GetAdaptersAddresses(0, 0, (IntPtr)0, PAdaptersAddresses, ref pOutLen);
}
IP_Adapter_Addresses adds = new IP_Adapter_Addresses();
IntPtr pTemp = PAdaptersAddresses;
while (pTemp != (IntPtr)0)
{
Marshal.PtrToStructure(pTemp, adds);
string adapterName = Marshal.PtrToStringAnsi(adds.AdapterName);
string FriendlyName = Marshal.PtrToStringAuto(adds.FriendlyName);
string tmpString = string.Empty;
for (int i = 0; i < 6; i++)
{
tmpString += string.Format("{0:X2}", adds.PhysicalAddress[i]);
if (i < 5)
{
tmpString += ":";
}
}
RegistryKey theLocalMachine = Registry.LocalMachine;
RegistryKey theSystem
= theLocalMachine.OpenSubKey(@"SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces");
RegistryKey theInterfaceKey = theSystem.OpenSubKey(adapterName);
if (theInterfaceKey != null)
{
macAddress = tmpString;
break;
}
pTemp = adds.Next;
}
}
catch
{ }
return macAddress;
}
3、 通过NetBios获取MAC地址
NetBIOS（网络基本输入/输出系统）是一套用于网络通讯的调用接口，包含NetBIOS Name和MAC地址等信息。该方法获取MAC地址的效率较高。
代码如下：
/// <summary>
/// 通过NetBios获取MAC地址
/// </summary>
/// <returns></returns>
public string GetMacAddressByNetBios()
{
string macAddress = "";
try
{
string addr = "";
int cb;
ASTAT adapter;
NCB Ncb = new NCB();
char uRetCode;
LANA_ENUM lenum; Ncb.ncb_command = (byte)NCBCONST.NCBENUM;
cb = Marshal.SizeOf(typeof(LANA_ENUM));
Ncb.ncb_buffer = Marshal.AllocHGlobal(cb);
Ncb.ncb_length = (ushort)cb;
uRetCode = Win32API.Netbios(ref Ncb);
lenum = (LANA_ENUM)Marshal.PtrToStructure(Ncb.ncb_buffer, typeof(LANA_ENUM));
Marshal.FreeHGlobal(Ncb.ncb_buffer);
if (uRetCode != (short)NCBCONST.NRC_GOODRET)
return ""; for (int i = 0; i < lenum.length; i++)
{
Ncb.ncb_command = (byte)NCBCONST.NCBRESET;
Ncb.ncb_lana_num = lenum.lana[i];
uRetCode = Win32API.Netbios(ref Ncb);
if (uRetCode != (short)NCBCONST.NRC_GOODRET)
return ""; Ncb.ncb_command = (byte)NCBCONST.NCBASTAT;
Ncb.ncb_lana_num = lenum.lana[i];
Ncb.ncb_callname[0] = (byte)'*';
cb = Marshal.SizeOf(typeof(ADAPTER_STATUS)) + Marshal.SizeOf(typeof(NAME_BUFFER)) * (int)NCBCONST.NUM_NAMEBUF;
Ncb.ncb_buffer = Marshal.AllocHGlobal(cb);
Ncb.ncb_length = (ushort)cb;
uRetCode = Win32API.Netbios(ref Ncb);
adapter.adapt = (ADAPTER_STATUS)Marshal.PtrToStructure(Ncb.ncb_buffer, typeof(ADAPTER_STATUS));
Marshal.FreeHGlobal(Ncb.ncb_buffer); if (uRetCode == (short)NCBCONST.NRC_GOODRET)
{
if (i > 0)
addr += ":";
addr = string.Format("{0,2:X}:{1,2:X}:{2,2:X}:{3,2:X}:{4,2:X}:{5,2:X}",
adapter.adapt.adapter_address[0],
adapter.adapt.adapter_address[1],
adapter.adapt.adapter_address[2],
adapter.adapt.adapter_address[3],
adapter.adapt.adapter_address[4],
adapter.adapt.adapter_address[5]);
}
}
macAddress = addr.Replace(' ', '0'); }
catch
{
}
return macAddress;
}
4、 通过DOS命令获得MAC地址
这个就是使用ipconfig命令，并需要在程序中启用cmd，程序中使用cmd如下即可，或参见http://blog.****.net/yysyangyangyangshan/article/details/6799489,
代码如下：
/// <summary>
/// 通过DOS命令获得MAC地址
/// </summary>
/// <returns></returns>
public string GetMacAddressByDos()
{
string macAddress = "";
Process p = null;
StreamReader reader = null;
try
{
ProcessStartInfo start = new ProcessStartInfo("cmd.exe"); start.FileName = "ipconfig";
start.Arguments = "/all"; start.CreateNoWindow = true; start.RedirectStandardOutput = true; start.RedirectStandardInput = true; start.UseShellExecute = false; p = Process.Start(start); reader = p.StandardOutput; string line = reader.ReadLine(); while (!reader.EndOfStream)
{
if (line.ToLower().IndexOf("physical address") > 0 || line.ToLower().IndexOf("物理地址") > 0)
{
int index = line.IndexOf(":");
index += 2;
macAddress = line.Substring(index);
macAddress = macAddress.Replace('-', ':');
break;
}
line = reader.ReadLine();
}
}
catch
{ }
finally
{
if (p != null)
{
p.WaitForExit();
p.Close();
}
if (reader != null)
{
reader.Close();
}
}
return macAddress;
}
5、 NetworkInterface获取MAC地址
NetworkInterface，提供网络接口的配置和统计信息。NetworkInterface.GetAllNetworkInterfaces，返回描述本地计算机上的网络接口的对象。
代码如下：
/// <summary>
/// 通过网络适配器获取MAC地址
/// </summary>
/// <returns></returns>
public string GetMacAddressByNetworkInformation()
{
string macAddress = "";
try
{
NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface adapter in nics)
{
if (!adapter.GetPhysicalAddress().ToString().Equals(""))
{
macAddress = adapter.GetPhysicalAddress().ToString();
for (int i = 1; i < 6; i++)
{
macAddress = macAddress.Insert(3 * i - 1, ":");
}
break;
}
} }
catch
{
}
return macAddress;
}
