TcpStatistics.FailedConnectionAttempts Property

Gets the number of failed Transmission Control Protocol (TCP) connection attempts.

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

public abstract long FailedConnectionAttempts { get; }

Property Value

Type: System.Int64
An Int64 value that specifies the total number of failed TCP connection attempts.

IETF RFC 2012 formally defines this value as, "The number of times TCP connections have made a direct transition to the CLOSED state from either the SYN-SENT state or the SYN-RCVD state, plus the number of times TCP connections have made a direct transition to the LISTEN state from the SYN-RCVD 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();    
}
