Property Value

Type: System::Int64

An Int64 value that specifies the total number of current TCP connections.

IETF RFC 2012 formally defines this value as, "The number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT."

The following code example displays connection information.

void ShowTcpConnectionStatistics()
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   TcpStatistics ^ tcpstat = properties->GetTcpIPv4Statistics();
   Console::WriteLine( "  Connection Data:" );
   Console::WriteLine( "      Current  ............................ : {0}", 
       tcpstat->CurrentConnections );
   Console::WriteLine( "      Cumulative .......................... : {0}", 
       tcpstat->CumulativeConnections );
   Console::WriteLine( "      Initiated ........................... : {0}", 
       tcpstat->ConnectionsInitiated );
   Console::WriteLine( "      Accepted ............................ : {0}", 
       tcpstat->ConnectionsAccepted );
   Console::WriteLine( "      Failed Attempts ..................... : {0}", 
       tcpstat->FailedConnectionAttempts );
   Console::WriteLine( "      Reset ............................... : {0}", 
       tcpstat->ResetConnections );
   Console::WriteLine( "      Errors .............................. : {0}", 
       tcpstat->ErrorsReceived );
}
