Exemplos
O exemplo de código seguinte apresenta informações para os adaptadores de rede do computador local que suportam IPv4.
public static void DisplayIPv4NetworkInterfaces()
{
NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
Console.WriteLine("IPv4 interface information for {0}.{1}",
properties.HostName, properties.DomainName);
Console.WriteLine();
foreach (NetworkInterface adapter in nics)
{
// Only display informatin for interfaces that support IPv4.
if (!adapter.Supports(NetworkInterfaceComponent.IPv4))
{
continue;
}
Console.WriteLine(adapter.Description);
// Underline the description.
Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length,'='));
IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
// Try to get the IPv4 interface properties.
IPv4InterfaceProperties p = adapterProperties.GetIPv4Properties();
// Display the IPv4 specific data.
Console.WriteLine(" Index ............................. : {0}", p.Index);
Console.WriteLine(" MTU ............................... : {0}", p.Mtu);
Console.WriteLine(" APIPA active....................... : {0}",
