如何通过 C# 获取网络打印机的 MAC 地址

我想获取 Intermec 条形码打印机的标识符,它使用网络接口,所以我想到了 MAC 地址。如何通过 C# 获取 MAC 地址?或者我可以直接获取打印机的序列号?
我假设您有网络打印机的 IP 地址,并且您的 PC 和打印机位于同一本地网络。您可以尝试一下该程序。
static void Main(string[] args)
{
PhysicalAddress pa = LocateMacAddress(IPAddress.Parse("172.16.0.99"));
Console.WriteLine(pa.ToString());
Console.ReadKey();
}
static PhysicalAddress LocateMacAddress(IPAddress ipAddress)
{
if (ipAddress.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork)
{
byte[] macAddressBytes = new byte[6];
int length = macAddressBytes.Length;
ArpErrorCodes c = (ArpErrorCodes)SendARP((uint)ipAddress.Address, 0, macAddressBytes, ref length);
if (c == ArpErrorCodes.None)
{
return new PhysicalAddress(macAddressBytes);
}
}
return PhysicalAddress.None;
}
[DllImport("iphlpapi.dll", ExactSpelling = true)]
public static extern int SendARP(uint DestIP, uint SrcIP, [Out] byte[] pMacAddr, ref int PhyAddrLen);
}
enum ArpErrorCodes
{
None = 0,
ERROR_GEN_FAILURE = 31,
ERROR_NOT_SUPPORTED = 50,
ERROR_BAD_NET_NAME = 67,
ERROR_BUFFER_OVERFLOW = 111,
ERROR_NOT_FOUND = 1168,
ERROR_INVALID_USER_BUFFER = 1784,
}
