Gets the local endpoint.

public:
 property System::Net::EndPoint ^ LocalEndPoint { System::Net::EndPoint ^ get(); };

public System.Net.EndPoint LocalEndPoint { get; }

public System.Net.EndPoint? LocalEndPoint { get; }

member this.LocalEndPoint : System.Net.EndPoint

Public ReadOnly Property LocalEndPoint As EndPoint

Property Value

EndPoint

The EndPoint that the Socket is using for communications.

Exceptions

SocketException

An error occurred when attempting to access the socket.

ObjectDisposedException

The Socket has been closed.

Examples

The following code example retrieves and displays the local and remote endpoints.

s->Connect(lep);

// Uses the RemoteEndPoint property.
Console::WriteLine("I am connected to {0} on port number {1}",
                   IPAddress::Parse((((IPEndPoint^)(s->RemoteEndPoint))->Address)->ToString()),
                   ((IPEndPoint^)(s->RemoteEndPoint))->Port.ToString());

// Uses the LocalEndPoint property.
Console::Write("My local IpAddress is : {0}\nI am connected on port number {1}",
               IPAddress::Parse((((IPEndPoint^)(s->LocalEndPoint))->Address)->ToString()),
               ((IPEndPoint^)(s->LocalEndPoint))->Port.ToString());

s.Connect(lep);

// Using the RemoteEndPoint property.
Console.WriteLine("I am connected to " + IPAddress.Parse(((IPEndPoint)s.RemoteEndPoint).Address.ToString()) + "on port number " + ((IPEndPoint)s.RemoteEndPoint).Port.ToString());

// Using the LocalEndPoint property.
Console.WriteLine("My local IpAddress is :" + IPAddress.Parse(((IPEndPoint)s.LocalEndPoint).Address.ToString()) + "I am connected on port number " + ((IPEndPoint)s.LocalEndPoint).Port.ToString());

s.Connect(lep)

' Using the RemoteEndPoint property.
Console.WriteLine("I am connected to ")
Console.WriteLine(IPAddress.Parse(CType(s.RemoteEndPoint, IPEndPoint).Address.ToString()))
Console.WriteLine("on port number ")
Console.WriteLine(CType(s.RemoteEndPoint, IPEndPoint).Port.ToString())

' Using the LocalEndPoint property.
Console.WriteLine("My local IpAddress is :")
Console.WriteLine(IPAddress.Parse(CType(s.LocalEndPoint, IPEndPoint).Address.ToString()))
Console.WriteLine("I am connected on port number ")
Console.WriteLine(CType(s.LocalEndPoint, IPEndPoint).Port.ToString())

Remarks

The LocalEndPoint property gets an EndPoint that contains the local IP address and port number to which your Socket is bound. You must cast this EndPoint to an IPEndPoint before retrieving any information. You can then call the IPEndPoint.Address method to retrieve the local IPAddress, and the IPEndPoint.Port method to retrieve the local port number.

The LocalEndPoint property is usually set after you make a call to the Bind method. If you allow the system to assign your socket's local IP address and port number, the LocalEndPoint property will be set after the first I/O operation. For connection-oriented protocols, the first I/O operation would be a call to the Connect or Accept method. For connectionless protocols, the first I/O operation would be any of the send or receive calls.

Note

If you receive a SocketException, use the SocketException.ErrorCode property to obtain the specific error code. After you have obtained this code, refer to the Windows Sockets version 2 API error code documentation for a detailed description of the error.

Note

This member outputs trace information when you enable network tracing in your application. For more information, see Network Tracing in .NET Framework.
