NetworkInterface.Speed Propriété

Définition

Espace de noms:

System.Net.NetworkInformation

Assembly:

System.Net.NetworkInformation.dll

Source:

NetworkInterface.cs

Obtient la vitesse de l'interface réseau.

public:
 virtual property long Speed { long get(); };

public virtual long Speed { get; }

member this.Speed : int64

Public Overridable ReadOnly Property Speed As Long

Valeur de propriété

Int64

Valeur Int64 qui spécifie la vitesse en bits par seconde.

Exemples

L’exemple de code suivant illustre l’affichage de la vitesse des interfaces sur l’ordinateur local.

void ShowInterfaceSpeedAndQueue()
{
   array<NetworkInterface^>^adapters = NetworkInterface::GetAllNetworkInterfaces();
   System::Collections::IEnumerator^ myEnum9 = adapters->GetEnumerator();
   while ( myEnum9->MoveNext() )
   {
      NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum9->Current);
      IPInterfaceProperties ^ properties = adapter->GetIPProperties();
      IPv4InterfaceStatistics ^ stats = adapter->GetIPv4Statistics();
      Console::WriteLine( adapter->Description );
      Console::WriteLine( "     Speed .................................: {0}", 
         adapter->Speed );
      Console::WriteLine( "     Output queue length....................: {0}", 
         stats->OutputQueueLength );
   }
}

public static void ShowInterfaceSpeedAndQueue()
{
    NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in adapters)
    {
        IPInterfaceProperties properties = adapter.GetIPProperties();
        IPv4InterfaceStatistics stats = adapter.GetIPv4Statistics();
         Console.WriteLine(adapter.Description);
        Console.WriteLine("     Speed .................................: {0}",
            adapter.Speed);
        Console.WriteLine("     Output queue length....................: {0}",
            stats.OutputQueueLength);
    }
}

Public Shared Sub ShowInterfaceSpeedAndQueue() 
    Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
    Dim adapter As NetworkInterface
    For Each adapter In  adapters
        Dim properties As IPInterfaceProperties = adapter.GetIPProperties()
        Dim stats As IPv4InterfaceStatistics = adapter.GetIPv4Statistics()
        Console.WriteLine(adapter.Description)
        Console.WriteLine("     Speed .................................: {0}", adapter.Speed)
        Console.WriteLine("     Output queue length....................: {0}", stats.OutputQueueLength)
    Next adapter

End Sub

Remarques

La valeur retournée par cette propriété est signalée par l’interface réseau. Il n’est pas calculé dynamiquement.
