IPHostEntry.AddressList Eigenschap

Definitie

Naamruimte:
System.Net
Assembly:
System.dll
Assembly:
netstandard.dll

Hiermee wordt een lijst met IP-adressen ophaalt of ingesteld die zijn gekoppeld aan een host.

public:
 property cli::array <System::Net::IPAddress ^> ^ AddressList { cli::array <System::Net::IPAddress ^> ^ get(); void set(cli::array <System::Net::IPAddress ^> ^ value); };
public System.Net.IPAddress[] AddressList { get; set; }
member this.AddressList : System.Net.IPAddress[] with get, set
Public Property AddressList As IPAddress()

Waarde van eigenschap

IPAddress[]

Een matrix van het type IPAddress dat IP-adressen bevat die worden omgezet in de hostnamen die zich in de Aliases eigenschap bevinden.

Voorbeelden

In het volgende voorbeeld wordt de AddressList eigenschap gebruikt voor toegang tot de IP-adressen die zijn gekoppeld aan de IPHostEntry.


public void GetIpAddressList(String hostString)
{
    try
    {
        // Get 'IPHostEntry' object containing information like host name, IP addresses, aliases for a host.
        IPHostEntry hostInfo = Dns.GetHostByName(hostString);
        Console.WriteLine("Host name : " + hostInfo.HostName);
        Console.WriteLine("IP address List : ");
        for(int index=0; index < hostInfo.AddressList.Length; index++)
        {
            Console.WriteLine(hostInfo.AddressList[index]);
        }
    }
    catch(SocketException e)
    {
        Console.WriteLine("SocketException caught!!!");
        Console.WriteLine("Source : " + e.Source);
        Console.WriteLine("Message : " + e.Message);
    }
    catch(ArgumentNullException e)
    {
        Console.WriteLine("ArgumentNullException caught!!!");
        Console.WriteLine("Source : " + e.Source);
        Console.WriteLine("Message : " + e.Message);
    }
    catch(Exception e)
    {
        Console.WriteLine("Exception caught!!!");
        Console.WriteLine("Source : " + e.Source);
        Console.WriteLine("Message : " + e.Message);
    }
}

Public Sub GetIpAddressList(hostString As [String])
    Try
        ' Get 'IPHostEntry' object which contains information like host name, IP addresses, aliases
    ' for specified url
        Dim hostInfo As IPHostEntry = Dns.GetHostByName(hostString)
        Console.WriteLine(("Host name : " + hostInfo.HostName))
        Console.WriteLine("IP address List : ")
        Dim index As Integer
        For index = 0 To hostInfo.AddressList.Length - 1
            Console.WriteLine(hostInfo.AddressList(index))
        Next index
    Catch e As SocketException
        Console.WriteLine("SocketException caught!!!")
        Console.WriteLine(("Source : " + e.Source))
        Console.WriteLine(("Message : " + e.Message))
    Catch e As ArgumentNullException
        Console.WriteLine("ArgumentNullException caught!!!")
        Console.WriteLine(("Source : " + e.Source))
        Console.WriteLine(("Message : " + e.Message))
    Catch e As Exception
        Console.WriteLine("Exception caught!!!")
        Console.WriteLine(("Source : " + e.Source))
        Console.WriteLine(("Message : " + e.Message))
    End Try
End Sub
