Ağ Arayüzleri

NetworkInterface sınıfı

NetworkInterface Sınıfı yazısına taşıdım.

MAC Adresini Alma
WMI ile ağ arayüzleri dolaşılır

ManagementObjectSearcher mos = new ManagementObjectSearcher
("select * from Win32_NetworkAdapterConfiguration");
foreach (ManagementObject mo in mos.Get())
{
  string mac = mo["MACAddress"].ToString();
  
}

IP Adresi Atama
Bazen statik bir IP adresi atamak isteriz.WMI kullanılabilir.

private static void SetIP(string ip_address, string subnet_mask)
{
  ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
  ManagementObjectCollection objMOC = mc.GetInstances();

  foreach (ManagementObject objMO in objMOC) {
    if ((bool)objMO("IPEnabled")) {
      try {
        ManagementBaseObject setIP = default(ManagementBaseObject);
        ManagementBaseObject newIP = objMO.GetMethodParameters("EnableStatic");

        newIP("IPAddress") = new string[] { ip_address };
        newIP("SubnetMask") = new string[] { subnet_mask };

        setIP = objMO.InvokeMethod("EnableStatic", newIP, null);
      }
      catch (Exception generatedExceptionName) {
        throw;
      }
    }

  }
}
