NetworkInterface.Supports(NetworkInterfaceComponent) Methode

Definitie

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

Hiermee wordt een Boolean waarde opgehaald die aangeeft of de interface het opgegeven protocol ondersteunt.

public:
 abstract bool Supports(System::Net::NetworkInformation::NetworkInterfaceComponent networkInterfaceComponent);
public:
 virtual bool Supports(System::Net::NetworkInformation::NetworkInterfaceComponent networkInterfaceComponent);
public abstract bool Supports(System.Net.NetworkInformation.NetworkInterfaceComponent networkInterfaceComponent);
public virtual bool Supports(System.Net.NetworkInformation.NetworkInterfaceComponent networkInterfaceComponent);
abstract member Supports : System.Net.NetworkInformation.NetworkInterfaceComponent -> bool
abstract member Supports : System.Net.NetworkInformation.NetworkInterfaceComponent -> bool
override this.Supports : System.Net.NetworkInformation.NetworkInterfaceComponent -> bool
Public MustOverride Function Supports (networkInterfaceComponent As NetworkInterfaceComponent) As Boolean
Public Overridable Function Supports (networkInterfaceComponent As NetworkInterfaceComponent) As Boolean

Parameters

networkInterfaceComponent
NetworkInterfaceComponent

Een NetworkInterfaceComponent waarde.

Retouren

Boolean

true als het opgegeven protocol wordt ondersteund; anders, false.

Voorbeelden

In het volgende codevoorbeeld worden statistieken weergegeven voor IPV4-interfaces op de lokale computer.

public static void DisplayIPv4NetworkInterfaces()
{
    NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    Console.WriteLine("IPv4 interface information for {0}.{1}",
       properties.HostName, properties.DomainName);
    Console.WriteLine();

    foreach (NetworkInterface adapter in nics)
    {
        // Only display informatin for interfaces that support IPv4.
        if (!adapter.Supports(NetworkInterfaceComponent.IPv4))
        {
            continue;
        }
        Console.WriteLine(adapter.Description);
        // Underline the description.
        Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length,'='));
        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
        // Try to get the IPv4 interface properties.
        IPv4InterfaceProperties p = adapterProperties.GetIPv4Properties();

        // Display the IPv4 specific data.
        Console.WriteLine("  Index ............................. : {0}", p.Index);
        Console.WriteLine("  MTU ............................... : {0}", p.Mtu);
        Console.WriteLine("  APIPA active....................... : {0}",
            p.IsAutomaticPrivateAddressingActive);

            p.IsForwardingEnabled);
        Console.WriteLine("  Uses WINS ......................... : {0}",
            p.UsesWins);
        Console.WriteLine();
    }
}
