UdpStatistics.UdpListeners Propriedade
Definição
Obtém o número de pontos de extremidade locais que estão ouvindo datagramas de protocolo UDP.Gets the number of local endpoints that are listening for User Datagram Protocol (UDP) datagrams.
public:
abstract property int UdpListeners { int get(); };
public abstract int UdpListeners { get; }
member this.UdpListeners : int
Public MustOverride ReadOnly Property UdpListeners As Integer
Valor da propriedade
Um Int64 valor que especifica o número total de soquetes que estão escutando em datagramas UDP.An Int64 value that specifies the total number of sockets that are listening for UDP datagrams.
Exemplos
O exemplo de código a seguir exibe as estatísticas de UDP para a versão de protocolo da Internet especificada.The following code example displays the UDP statistics for the specified Internet Protocol version.
void ShowUdpStatistics( NetworkInterfaceComponent version )
{
IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
UdpStatistics ^ udpStat = nullptr;
switch ( version )
{
case NetworkInterfaceComponent::IPv4:
udpStat = properties->GetUdpIPv4Statistics();
Console::WriteLine( "UDP IPv4 Statistics" );
break;
case NetworkInterfaceComponent::IPv6:
udpStat = properties->GetUdpIPv6Statistics();
Console::WriteLine( "UDP IPv6 Statistics" );
break;
default:
throw gcnew ArgumentException( "version" );
break;
}
Console::WriteLine( " Datagrams Received ...................... : {0}", udpStat->DatagramsReceived );
Console::WriteLine( " Datagrams Sent .......................... : {0}", udpStat->DatagramsSent );
Console::WriteLine( " Incoming Datagrams Discarded ............ : {0}", udpStat->IncomingDatagramsDiscarded );
Console::WriteLine( " Incoming Datagrams With Errors .......... : {0}", udpStat->IncomingDatagramsWithErrors );
Console::WriteLine( " UDP Listeners ........................... : {0}", udpStat->UdpListeners );
Console::WriteLine( "" );
}
public static void ShowUdpStatistics(NetworkInterfaceComponent version)

UdpStatistics udpStat = null;
switch (version)
{
case NetworkInterfaceComponent.IPv4:
udpStat = properties.GetUdpIPv4Statistics();
Console.WriteLine("UDP IPv4 Statistics");
break;
case NetworkInterfaceComponent.IPv6:

Console.WriteLine("UDP IPv6 Statistics");
break;
default:
throw new ArgumentException("version");
// break;
}
Console.WriteLine(" Datagrams Received ...................... : {0}",
