示例

下面的代码示例获取 对象 GetIPv4Properties 并显示其数据。

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();
    }
}

注解

此类提供对支持 IPv4 的网络接口的配置和地址信息的访问权限。 不创建此类的实例;它们由 GetIPv4Properties 方法返回。

有关 IPV6 属性，请参阅 GetIPv6Properties。

构造函数

IPv4InterfaceProperties()

初始化 IPv4InterfaceProperties 类的新实例。

属性

Index

获取 Internet 协议版本 4 (IPv4) 地址的网络接口的索引。
IsAutomaticPrivateAddressingActive

获取一个 Boolean 值，该值指示此接口是否具有自动专用 IP 寻址 (APIPA) 地址。
IsAutomaticPrivateAddressingEnabled

获取一个 Boolean 值，该值指示此接口是否启用了自动专用 IP 寻址 (APIPA)。
IsDhcpEnabled

获取一个 Boolean 值，该值指示此接口是否配置为使用动态主机配置协议 (DHCP) 服务器来获取 IP 地址。
IsForwardingEnabled

获取一个 Boolean 值，该值指示此接口是否可以转发（路由）数据包。
Mtu

获取此网络接口的最大传输单位 (MTU)。
UsesWins

获取 Boolean 值，该值指示接口是否使用 Windows Internet 名称服务 (WINS)。

方法

Equals(Object)

确定指定对象是否等于当前对象。

(继承自 Object)
GetHashCode()

作为默认哈希函数。

(继承自 Object)
GetType()

获取当前实例的 Type。

(继承自 Object)
MemberwiseClone()

创建当前 Object 的浅表副本。

(继承自 Object)
ToString()

返回表示当前对象的字符串。

(继承自 Object)
