Examples

The following example displays endpoint information for active TCP connections.

void GetTcpConnections()
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   array<TcpConnectionInformation^>^connections = properties->GetActiveTcpConnections();
   System::Collections::IEnumerator^ myEnum = connections->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      TcpConnectionInformation ^ t = safe_cast<TcpConnectionInformation ^>(myEnum->Current);
      Console::Write( "Local endpoint: {0} ", t->LocalEndPoint->Address );
      Console::Write( "Remote endpoint: {0} ", t->RemoteEndPoint->Address );
      Console::WriteLine( "{0}", t->State );
   }
}

public static void GetTcpConnections()
{
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    TcpConnectionInformation[] connections = properties.GetActiveTcpConnections();

    foreach (TcpConnectionInformation t in connections)
    {
        Console.Write("Local endpoint: {0} ",t.LocalEndPoint.Address);
        Console.Write("Remote endpoint: {0} ",t.RemoteEndPoint.Address);
        Console.WriteLine("{0}",t.State);
    }
    Console.WriteLine();
}

Public Shared Sub GetTcpConnections() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim connections As TcpConnectionInformation() = properties.GetActiveTcpConnections()
    
    Dim t As TcpConnectionInformation
    For Each t In  connections
        Console.Write("Local endpoint: {0} ", t.LocalEndPoint.Address)
        Console.Write("Remote endpoint: {0} ", t.RemoteEndPoint.Address)
        Console.WriteLine("{0}", t.State)
    Next t

Remarks

TCP is a connection-oriented reliable protocol for transporting data between networked computers. It is defined in IETF RFC 793.

Constructors

TcpConnectionInformation()

Initializes a new instance of the TcpConnectionInformation class.

Properties

LocalEndPoint	Gets the local endpoint of a Transmission Control Protocol (TCP) connection.
RemoteEndPoint	Gets the remote endpoint of a Transmission Control Protocol (TCP) connection.
State	Gets the state of this Transmission Control Protocol (TCP) connection.
