TcpStatistics.FailedConnectionAttempts Eigenschap

Definitie

Naamruimte:
System.Net.NetworkInformation
Assembly:
System.dll
Assembly:
netstandard.dll

Hiermee haalt u het aantal mislukte TCP-verbindingspogingen (Transmission Control Protocol) op.

public:
 abstract property long FailedConnectionAttempts { long get(); };
public abstract long FailedConnectionAttempts { get; }
member this.FailedConnectionAttempts : int64
Public MustOverride ReadOnly Property FailedConnectionAttempts As Long

Waarde van eigenschap

Int64

Een Int64 waarde die het totale aantal mislukte TCP-verbindingspogingen aangeeft.

Voorbeelden

In het volgende codevoorbeeld worden verbindingsgegevens weergegeven.

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();
}

Public Shared Sub ShowTcpConnectionStatistics() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim tcpstat As TcpStatistics = 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)

Opmerkingen

IETF RFC 2012 definieert deze waarde formeel als: 'Het aantal keren dat TCP-verbindingen een directe overgang hebben gemaakt naar de status CLOSED van de status GESLOTEN van de status SYN-SENT of de status SYN-RCVD, plus het aantal keren dat TCP-verbindingen een directe overgang hebben gemaakt naar de LISTEN-status van de SYN-RCVD status.'
