IPInterfaceProperties.GatewayAddresses 属性

定义

获取此接口的 IPv4 网关地址。

public:
 abstract property System::Net::NetworkInformation::GatewayIPAddressInformationCollection ^ GatewayAddresses { System::Net::NetworkInformation::GatewayIPAddressInformationCollection ^ get(); };
[System.Runtime.Versioning.UnsupportedOSPlatform("android")]
public abstract System.Net.NetworkInformation.GatewayIPAddressInformationCollection GatewayAddresses { get; }
public abstract System.Net.NetworkInformation.GatewayIPAddressInformationCollection GatewayAddresses { get; }
[<System.Runtime.Versioning.UnsupportedOSPlatform("android")>]
member this.GatewayAddresses : System.Net.NetworkInformation.GatewayIPAddressInformationCollection
member this.GatewayAddresses : System.Net.NetworkInformation.GatewayIPAddressInformationCollection
Public MustOverride ReadOnly Property GatewayAddresses As GatewayIPAddressInformationCollection

属性值

GatewayIPAddressInformationCollection,它包含网关的地址信息,如果找不到网关,则包含空数组。

示例

下面的代码示例显示本地计算机上网络接口的网关地址。

public static void DisplayGatewayAddresses()
{
    Console.WriteLine("Gateways");
    NetworkInterface[] adapters  = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in adapters)
    {
        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
        GatewayIPAddressInformationCollection addresses = adapterProperties.GatewayAddresses;
        if (addresses.Count >0)
        {
            Console.WriteLine(adapter.Description);
            foreach (GatewayIPAddressInformation address in addresses)
            {
                Console.WriteLine("  Gateway Address ......................... : {0}",
                    address.Address.ToString());
            }
            Console.WriteLine();
        }
    }
}
Public Shared Sub DisplayGatewayAddresses() 
    Console.WriteLine("Gateways")
    Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
    Dim adapter As NetworkInterface
    For Each adapter In  adapters
        Dim adapterProperties As IPInterfaceProperties = adapter.GetIPProperties()
        Dim addresses As GatewayIPAddressInformationCollection = adapterProperties.GatewayAddresses
        If addresses.Count > 0 Then
            Console.WriteLine(adapter.Description)
            Dim address As GatewayIPAddressInformation
            For Each address In  addresses
                Console.WriteLine("  Gateway Address ......................... : {0}", address.ToString())
            Next address
            Console.WriteLine()
        End If
    Next adapter

End Sub

注解
