TcpStatistics Class
.NET Framework 2.0
Note: This class is new in the .NET Framework version 2.0.
Provides Transmission Control Protocol (TCP) statistical data.
Namespace: System.Net.NetworkInformation
Assembly: System (in system.dll)
Assembly: System (in system.dll)
Instances of this class are returned by the GetTcpIPv4Statistics and GetTcpIPv6Statistics methods, to give applications access to TCP traffic information.
The information in this class correlates to the management information objects described in http://www.ietf.org/rfc/rfc2012.txt.
The following code example displays the TCP statistics for the specified address family.
public static void ShowTcpStatistics(NetworkInterfaceComponent version) { IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties(); TcpStatistics tcpstat = null; Console.WriteLine(""); switch (version) { case NetworkInterfaceComponent.IPv4: tcpstat = properties.GetTcpIPv4Statistics(); Console.WriteLine("TCP/IPv4 Statistics:"); break; case NetworkInterfaceComponent.IPv6: tcpstat = properties.GetTcpIPv6Statistics(); Console.WriteLine("TCP/IPv6 Statistics:"); break; default: throw new ArgumentException("version"); break; } Console.WriteLine(" Minimum Transmission Timeout............. : {0}", tcpstat.MinimumTransmissionTimeout); Console.WriteLine(" Maximum Transmission Timeout............. : {0}", tcpstat.MaximumTransmissionTimeout); 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(""); Console.WriteLine(" Segment Data:"); Console.WriteLine(" Received ........................... : {0}", tcpstat.SegmentsReceived); Console.WriteLine(" Sent ................................ : {0}", tcpstat.SegmentsSent); Console.WriteLine(" Retransmitted ....................... : {0}", tcpstat.SegmentsResent); Console.WriteLine(""); }
