1。用C#调用DOS命令获取本机网卡的MAC地址
System.Diagnostics.Process p=new System.Diagnostics.Process();
p.StartInfo.CreateNoWindow=true;
p.StartInfo.UseShellExecute=false;
p.StartInfo.RedirectStandardOutput=true;
p.StartInfo.FileName="ipconfig";
p.StartInfo.Arguments="/all";
p.Start();
p.WaitForExit();
string s=p.StandardOutput.ReadToEnd();
MessageBox.Show(s.Substring(s.IndexOf("Physical Address. . . . . . . . . :")+36,17));
2。使用API，利用ARP协议，只能获得同网段计算机的MAC
#region By ARP
[DllImport("Iphlpapi.dll")]
private static extern int SendARP(Int32 dest, Int32 host, ref Int64 mac, ref Int32 length);
[DllImport("Ws2_32.dll")]
private static extern Int32 inet_addr(string ip);
public static string GetMacByARP(string clientIP)
{
string ip = clientIP;
Int32 ldest = inet_addr(ip);
Int64 macinfo = new Int64();
Int32 len = 6;
try
{
SendARP(ldest, 0, ref macinfo, ref len);
}
catch
{
return "";
}
string originalMACAddress = Convert.ToString(macinfo, 16);
if (originalMACAddress.Length < 12)
{
originalMACAddress = originalMACAddress.PadLeft(12, '0');
}
string macAddress;
if (originalMACAddress != "0000" && originalMACAddress.Length == 12)
{
string mac1, mac2, mac3, mac4, mac5, mac6;
mac1 = originalMACAddress.Substring(10, 2);
mac2 = originalMACAddress.Substring(8, 2);
mac3 = originalMACAddress.Substring(6, 2);
mac4 = originalMACAddress.Substring(4, 2);
mac5 = originalMACAddress.Substring(2, 2);
mac6 = originalMACAddress.Substring(0, 2);
macAddress = mac1 + "-" + mac2 + "-" + mac3 + "-" + mac4 + "-" + mac5 + "-" + mac6;
}
else
{
macAddress = "";
}
return macAddress.ToUpper();
}
public static IPAddress[] GetLocalIP()
{
string hostName = Dns.GetHostName();
IPHostEntry ipEntry = Dns.GetHostByName(hostName);
return ipEntry.AddressList;
}
#endregion
