Devoluções

NetworkInterface[]

Um NetworkInterface array que contém objetos que descrevem as interfaces de rede disponíveis, ou um array vazio se não forem detetadas interfaces.

Atributos
UnsupportedOSPlatformAttribute

Exceções

NetworkInformationException

Uma chamada de função do sistema Windows falhou.

Exemplos

O seguinte exemplo de código apresenta informações de configuração do Domain Name Service (DNS) para os adaptadores de rede do computador local.

public static void DisplayDnsConfiguration()
{
    NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in adapters)
    {
        IPInterfaceProperties properties = adapter.GetIPProperties();
        Console.WriteLine(adapter.Description);
        Console.WriteLine("  DNS suffix .............................. : {0}",
            properties.DnsSuffix);
        Console.WriteLine("  DNS enabled ............................. : {0}",
            properties.IsDnsEnabled);
        Console.WriteLine("  Dynamically configured DNS .............. : {0}",
            properties.IsDynamicDnsEnabled);
    }
    Console.WriteLine();
}

Public Shared Sub DisplayDnsConfiguration() 
    Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
    Dim adapter As NetworkInterface
    For Each adapter In  adapters
        Dim properties As IPInterfaceProperties = adapter.GetIPProperties()
        Console.WriteLine(adapter.Description)
        Console.WriteLine("  DNS suffix................................. :{0}", properties.DnsSuffix)
        Console.WriteLine("  DNS enabled ............................. : {0}", properties.IsDnsEnabled)
        Console.WriteLine("  Dynamically configured DNS .............. : {0}", properties.IsDynamicDnsEnabled)
    Next adapter

End Sub

Observações

As interfaces de rede de um computador fornecem conectividade de rede. As interfaces de rede também são conhecidas como adaptadores de rede.
