NetworkInterface.Speed 属性

定义

命名空间:

System.Net.NetworkInformation

程序集:

System.Net.NetworkInformation.dll

Source:

NetworkInterface.cs

获取网络接口的速度。

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

public virtual long Speed { get; }

member this.Speed : int64

Public Overridable ReadOnly Property Speed As Long

属性值

Int64

Int64 值，指定速度（每位/秒为单位）。

示例

下面的代码示例演示了在本地计算机上显示接口的速度。

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

注解

此属性返回的值由网络接口报告。 它不是动态计算的。
