Egenskapsvärde

IPAddressCollection

En IPAddressCollection som innehåller adressinformationen för DHCP-servrar eller en tom matris om inga servrar hittas.

Attribut
UnsupportedOSPlatformAttribute

Exempel

I följande kodexempel visas DHCP-adressinformationen för nätverksgränssnitten på den lokala datorn.

public static void DisplayDhcpServerAddresses()
{
    Console.WriteLine("DHCP Servers");
    NetworkInterface[] adapters  = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in adapters)
    {

        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
        IPAddressCollection addresses = adapterProperties.DhcpServerAddresses;
        if (addresses.Count >0)
        {
            Console.WriteLine(adapter.Description);
            foreach (IPAddress address in addresses)
            {
                Console.WriteLine("  Dhcp Address ............................ : {0}",
                    address.ToString());
            }
            Console.WriteLine();
        }
    }
}

Public Shared Sub DisplayDhcpServerAddresses() 
    Console.WriteLine("DHCP Servers")
    Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
    Dim adapter As NetworkInterface
    For Each adapter In  adapters
        
        Dim adapterProperties As IPInterfaceProperties = adapter.GetIPProperties()
        Dim addresses As IPAddressCollection = adapterProperties.DhcpServerAddresses
        If addresses.Count > 0 Then
            Console.WriteLine(adapter.Description)
            Dim address As IPAddress
            For Each address In  addresses
                Console.WriteLine("  Dhcp Address ............................ : {0}", address.ToString())
            Next address
            Console.WriteLine()
        End If
    Next adapter

End Sub

Kommentarer

Med DHCP (Dynamic Host Configuration Protocol) kan en dator hämta en nätverksadress från en DHCP-server, i stället för att använda en statisk (fast) nätverksadress. En DHCP-server tilldelar inte adresser permanent. I stället använder den tillfälligt en av ett antal tillgängliga adresser till datorn.
