在c#中格式化MAC地址

本文关键字：MAC 地址 格式化 | 更新日期: 2023-09-27 18:08:31

在我的c#应用程序中，我想通过使用NetworkInterface类获得我的MAC地址，如下所示:

NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces()
{
    mac = nic.GetPhysicalAddress()
}

但是这段代码返回没有':'或任何其他分隔符的MAC。

如何以这种格式检索MAC:88:88:88:88:87:88只使用上面的代码?

在c#中格式化MAC地址

try

mac = string.Join (":", (from z in nic.GetPhysicalAddress().GetAddressBytes() select z.ToString ("X2")).ToArray());

该命令的帮助显示了一种方法:

http://msdn.microsoft.com/en-us/library/system.net.networkinformation.physicaladdress.aspx 

    PhysicalAddress address = adapter.GetPhysicalAddress();
    byte[] bytes = address.GetAddressBytes();
    for(int i = 0; i< bytes.Length; i++)
    {
        // Display the physical address in hexadecimal.
        Console.Write("{0}", bytes[i].ToString("X2"));
        // Insert a hyphen after each byte, unless we are at the end of the 
        // address.
        if (i != bytes.Length -1)
        {
             Console.Write("-");
        }
    }
    Console.WriteLine();

使用eFloh的注释使用BitConverter我能够做到以下(假设mac是预定义为字符串)。

foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
{
    mac = BitConverter.ToString(nic.GetPhysicalAddress().GetAddressBytes()).Replace('-', ':');
    //Do whatever else necessary with each mac...
}

试试这样:

// Insert Colons on MAC
string MACwithColons = "";
for (int i = 0; i < MAC.Length; i++) {
  MACwithColons = MACwithColons + MAC.Substring(i, 2) + ":";
  i++;
}
MACwithColons = MACwithColons.Substring(0, MACwithColons.Length - 1); // Remove the last colon

在你想显示的地方，你必须这样做:

txtMac.text=getFormatMac(GetMacAddress());
public string GetMacAddress()
{
    NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
    String sMacAddress = string.Empty;
    foreach (NetworkInterface adapter in nics)
    {
         if (sMacAddress == String.Empty)// solo retorna la mac de la primera tarjeta
         {
              IPInterfaceProperties properties = adapter.GetIPProperties();
              sMacAddress = adapter.GetPhysicalAddress().ToString();
          }
    }
    return sMacAddress;
}
public string getFormatMac(string sMacAddress)
{
    string MACwithColons = "";
    for (int i = 0; i < macName.Length; i++)
    {
        MACwithColons = MACwithColons + macName.Substring(i, 2) + ":";
        i++;
    }
    MACwithColons = MACwithColons.Substring(0, MACwithColons.Length - 1);
    return MACwithColons;
}
