如何使用C＃获取IP地址的物理（MAC）地址？
从C＃开始，我想做相同的以下内容：
arp -a |findstr 192.168.1.254 或者，答案可以调用SendARP函数并获得结果。
这将允许我的应用程序执行一些需要MAC地址的其他处理。
SendARP P / Invoke是这样的：
[DllImport("iphlpapi.dll", ExactSpelling=true)] public static extern int SendARP( int destIp, int srcIP, byte[] macAddr, ref uint physicalAddrLen );
PInvoke.NET有这个例子：
IPAddress dst = IPAddress.Parse("192.168.2.1"); // the destination IP address byte[] macAddr = new byte[6]; uint macAddrLen = (uint)macAddr.Length; if (SendARP(BitConverter.ToInt32(dst.GetAddressBytes(), 0), 0, macAddr, ref macAddrLen) != 0) throw new InvalidOperationException("SendARP failed."); string[] str = new string[(int)macAddrLen]; for (int i=0; i
这是我的解决方案。
public static class MacResolver { /// /// Convert a string into Int32 /// [DllImport("Ws2_32.dll")] private static extern Int32 inet_addr(string ip); /// /// The main funtion /// [DllImport("Iphlpapi.dll")] private static extern int SendARP(Int32 dest, Int32 host, ref Int64 mac, ref Int32 len); /// /// Returns the MACAddress by a string. /// public static Int64 GetRemoteMAC(string remoteIP) { Int32 ldest = inet_addr(remoteIP); try { Int64 macinfo = 0; Int32 len = 6; int res = SendARP(ldest, 0, ref macinfo, ref len); return macinfo; } catch (Exception e) { return 0; } } /// /// Format a long/Int64 into string. /// public static string FormatMac(this Int64 mac, char separator) { if (mac <= 0) return "00-00-00-00-00-00"; char[] oldmac = Convert.ToString(mac, 16).PadLeft(12, '0').ToCharArray(); System.Text.StringBuilder newMac = new System.Text.StringBuilder(17); if (oldmac.Length < 12) return "00-00-00-00-00-00"; newMac.Append(oldmac[10]); newMac.Append(oldmac[11]); newMac.Append(separator); newMac.Append(oldmac[8]); newMac.Append(oldmac[9]); newMac.Append(separator); newMac.Append(oldmac[6]); newMac.Append(oldmac[7]); newMac.Append(separator); newMac.Append(oldmac[4]); newMac.Append(oldmac[5]); newMac.Append(separator); newMac.Append(oldmac[2]); newMac.Append(oldmac[3]); newMac.Append(separator); newMac.Append(oldmac[0]); newMac.Append(oldmac[1]); return newMac.ToString(); } }
挂钩到WMI子系统。 一些VBScript代码正朝着正确的方向发展
找到你自己的：
添加对System.Management的引用
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"); ManagementObjectCollection mcCol = mc.GetInstances(); foreach (ManagementObject mcObj in mcCol) { Console.WriteLine(mcObj["Caption"].ToString()); Console.WriteLine(mcObj["MacAddress"].ToString()); }
