TcpStatistics.ConnectionsAccepted Property

Gets the number of accepted Transmission Control Protocol (TCP) connection requests.

Namespace:  System.Net.NetworkInformation
Assembly:  System (in System.dll)

public abstract long ConnectionsAccepted { get; }

Property Value

Type: System.Int64
An Int64 value that specifies the total number of TCP connection requests accepted.

IETF RFC 2012 formally defines this value as, "The number of times TCP connections have made a direct transition to the SYN-RCVD state from the LISTEN state."

The following code example displays connection information.

public static 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);
    Console.WriteLine();    
}
void ShowTcpConnectionStatistics()
{
    IPGlobalProperties* properties = IPGlobalProperties::GetIPGlobalProperties();
    TcpStatistics* tcpstat = properties->GetTcpIPv4Statistics();

    Console::WriteLine(S"  Connection Data:");
    Console::WriteLine(S"      Current  ............................ : {0}", __box(tcpstat->CurrentConnections));
    Console::WriteLine(S"      Cumulative .......................... : {0}", __box(tcpstat->CumulativeConnections));
    Console::WriteLine(S"      Initiated ........................... : {0}", __box(tcpstat->ConnectionsInitiated));
    Console::WriteLine(S"      Accepted ............................ : {0}", __box(tcpstat->ConnectionsAccepted));
    Console::WriteLine(S"      Failed Attempts ..................... : {0}", __box(tcpstat->FailedConnectionAttempts));
    Console::WriteLine(S"      Reset ............................... : {0}", __box(tcpstat->ResetConnections));
    Console::WriteLine(S"      Errors .............................. : {0}", __box(tcpstat->ErrorsReceived));
