IPAddressInformation.Address Property

Definition

Gets the Internet Protocol (IP) address.

public:
 abstract property System::Net::IPAddress ^ Address { System::Net::IPAddress ^ get(); };
public abstract System.Net.IPAddress Address { get; }
member this.Address : System.Net.IPAddress
Public MustOverride ReadOnly Property Address As IPAddress

Property Value

An IPAddress instance that contains the IP address of an interface.

Examples

The following code example displays the multicast addresses for the network interfaces on the local computer.

void DisplayMulticastAddresses()
{
   int count = 0;
   
   Console::WriteLine( "Multicast Addresses" );
   array<NetworkInterface^>^adapters = NetworkInterface::GetAllNetworkInterfaces();
   System::Collections::IEnumerator^ myEnum15 = adapters->GetEnumerator();
   while ( myEnum15->MoveNext() )
   {
      NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum15->Current);
      IPInterfaceProperties ^ adapterProperties = adapter->GetIPProperties();
      MulticastIPAddressInformationCollection ^ multiCast = adapterProperties->MulticastAddresses;
      if ( multiCast->Count > 0 )
      {
         Console::WriteLine( adapter->Description );
         System::Collections::IEnumerator^ myEnum16 = multiCast->GetEnumerator();
         while ( myEnum16->MoveNext() )
         {
            MulticastIPAddressInformation ^ multi = safe_cast<MulticastIPAddressInformation ^>(myEnum16->Current);

            count++;   
         }
         Console::WriteLine();
      }
   }
    if (count == 0)
    {
        Console::WriteLine("  No multicast addresses were found.");
        Console::WriteLine();
    }

    }
    if (count == 0)
    {

        Console.WriteLine();
    }

Remarks

The IP address uniquely identifies the interface on the network.
