IPAddressInformation 类

定义

命名空间:

System.Net.NetworkInformation

程序集:

System.Net.NetworkInformation.dll

提供有关网络接口地址的信息。

public ref class IPAddressInformation abstract

public abstract class IPAddressInformation

type IPAddressInformation = class

Public MustInherit Class IPAddressInformation

继承

Object

IPAddressInformation

派生

System.Net.NetworkInformation.MulticastIPAddressInformation

System.Net.NetworkInformation.UnicastIPAddressInformation

示例

下面的代码示例显示本地计算机上网络接口的域名服务 (DNS) 地址。

void DisplayDnsAddresses()
{
   array<NetworkInterface^>^adapters = NetworkInterface::GetAllNetworkInterfaces();
   System::Collections::IEnumerator^ myEnum11 = adapters->GetEnumerator();
   while ( myEnum11->MoveNext() )
   {
      NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum11->Current);
      IPInterfaceProperties ^ adapterProperties = adapter->GetIPProperties();
      IPAddressCollection ^ dnsServers = adapterProperties->DnsAddresses;
      if ( dnsServers->Count > 0 )
      {
         Console::WriteLine( adapter->Description );
         System::Collections::IEnumerator^ myEnum12 = dnsServers->GetEnumerator();
         while ( myEnum12->MoveNext() )
         {
            IPAddress ^ dns = safe_cast<IPAddress ^>(myEnum12->Current);
            Console::WriteLine( "  DNS Servers ............................. : {0}", 
               dns->ToString());
         }
      }
   }
}

public static void DisplayDnsAddresses()
{
    NetworkInterface[] adapters  = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in adapters)
    {

        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
        IPAddressCollection dnsServers = adapterProperties.DnsAddresses;
        if (dnsServers.Count > 0)
        {
            Console.WriteLine(adapter.Description);
            foreach (IPAddress dns in dnsServers)
            {
                Console.WriteLine("  DNS Servers ............................. : {0}",
                    dns.ToString());
            }
            Console.WriteLine();
        }
    }
}

Public Shared Sub DisplayDnsAddresses() 
    Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
    Dim adapter As NetworkInterface
    For Each adapter In  adapters
        
        Dim adapterProperties As IPInterfaceProperties = adapter.GetIPProperties()
        Dim dnsServers As IPAddressCollection = adapterProperties.DnsAddresses
        If dnsServers.Count > 0 Then
            Console.WriteLine(adapter.Description)
            Dim dns As IPAddress
            For Each dns In  dnsServers
                Console.WriteLine("  DNS Servers ............................. : {0}",dns.ToString() )
            Next dns
        End If
    Next adapter

End Sub

注解

不创建此类的实例;实例由 类中 IPInterfaceProperties 的方法返回。

构造函数

IPAddressInformation()

初始化 IPAddressInformation 类的新实例。

属性

Address	获取 Internet 协议 (IP) 地址。
IsDnsEligible	获取一个 Boolean 值，该值指示 Internet 协议 (IP) 地址出现在域名系统 (DNS) 服务器数据库中时是否有效。
IsTransient	获取一个 Boolean 值，该值指示 Internet 协议 (IP) 地址是否为瞬态（群集地址）。

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)
