The following example displays endpoint information for active TCP connections.
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 End Sub 'GetTcpConnections
void GetTcpConnections()
{
IPGlobalProperties* properties = IPGlobalProperties::GetIPGlobalProperties();
TcpConnection* connections[] = properties->GetActiveTcpConnections();
System::Collections::IEnumerator* myEnum = connections->GetEnumerator();
while (myEnum->MoveNext())
{
TcpConnection* t = __try_cast<TcpConnection*>(myEnum->Current);
Console::Write(S"Local endpoint: {0} ",t->LocalEndPoint->Address);
Console::Write(S"Remote endpoint: {0} ",t->RemoteEndPoint->Address);
Console::WriteLine(S"{0}", __box(t->State));
}
