Definition
Important

Gets the underlying EndPoint of the current TcpListener.
public:
property System::Net::EndPoint ^ LocalEndpoint { System::Net::EndPoint ^ get(); };
public System.Net.EndPoint LocalEndpoint { get; }
member this.LocalEndpoint : System.Net.EndPoint
Public ReadOnly Property LocalEndpoint As EndPoint
Property Value
The EndPoint to which the Socket is bound.
Examples
The following code example displays the local IP address and port number on which the TcpListener is listening for incoming connection requests.
try
{
// Use the Pending method to poll the underlying socket instance for client connection requests.
TcpListener^ tcpListener = gcnew TcpListener( portNumber );
tcpListener->Start();
if ( !tcpListener->Pending() )
{
Console::WriteLine( "Sorry, no connection requests have arrived" );
}
else
{
//Accept the pending client connection and return a TcpClient object^ initialized for communication.
TcpClient^ tcpClient = tcpListener->AcceptTcpClient();
// Using the RemoteEndPoint property.
Console::WriteLine( "I am listening for connections on {0} on port number {1}",
IPAddress::Parse( ( (IPEndPoint^)(tcpListener->LocalEndpoint) )->Address->ToString() ),
( (IPEndPoint^)(tcpListener->LocalEndpoint) )->Port );
const int portNumber = 13;
try
{
// Use the Pending method to poll the underlying socket instance for client connection requests.
IPAddress ipAddress = Dns.Resolve("localhost").AddressList[0];
TcpListener tcpListener = new TcpListener(ipAddress, portNumber);
tcpListener.Start();
if (!tcpListener.Pending())
{
Console.WriteLine("Sorry, no connection requests have arrived");
}
else
{
//Accept the pending client connection and return a TcpClient object initialized for communication.
TcpClient tcpClient = tcpListener.AcceptTcpClient();
// Using the RemoteEndPoint property.
Console.WriteLine("I am listening for connections on " +
IPAddress.Parse(((IPEndPoint)tcpListener.LocalEndpoint).Address.ToString()) +
"on port number " + ((IPEndPoint)tcpListener.LocalEndpoint).Port.ToString());
//Close the tcpListener and tcpClient instances
tcpClient.Close();
}
tcpListener.Stop();
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
Try
Dim ipAddress As IPAddress = Dns.Resolve("localhost").AddressList(0)
Dim tcpListener As New TcpListener(ipAddress, portNumber)
tcpListener.Start()
' Use the Pending method to poll the underlying socket instance for client connection requests.
If Not tcpListener.Pending() Then
Console.WriteLine("Sorry, no connection requests have arrived")
Else
'Accept the pending client connection and return a TcpClient object initialized for communication.
Dim tcpClient As TcpClient = tcpListener.AcceptTcpClient()
' Using the RemoteEndPoint property.
Console.Write("I am listening for connections on ")
Console.Writeline(IPAddress.Parse(CType(tcpListener.LocalEndpoint, IPEndPoint).Address.ToString()))
Console.Write("on port number ")
Console.Write(CType(tcpListener.LocalEndpoint, IPEndPoint).Port.ToString())
Remarks
You can use the LocalEndpoint property to identify the local network interface and port number being used to listen for incoming client connection requests, after a socket connection has been made. You must first cast this EndPoint to an IPEndPoint. You can then call the IPEndPoint.Address property to retrieve the local IP address, and the IPEndPoint.Port property to retrieve the local port number.
