NetworkInterface.Speed Property

Definition

Namespace:

System.Net.NetworkInformation

Assembly:

System.Net.NetworkInformation.dll

Source:

NetworkInterface.cs

Gets the speed of the network interface.

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

public virtual long Speed { get; }

member this.Speed : int64

Public Overridable ReadOnly Property Speed As Long

Property Value

Int64

A Int64 value that specifies the speed in bits per second.

Examples

The following code example demonstrates displaying the speed of interfaces on the local computer.

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

Remarks

The value returned by this property is reported by the network interface. It is not computed dynamically.
