IPInterfaceProperties.DhcpServerAddresses 属性

public:
 abstract property System::Net::NetworkInformation::IPAddressCollection ^ DhcpServerAddresses { System::Net::NetworkInformation::IPAddressCollection ^ get(); };

public abstract System.Net.NetworkInformation.IPAddressCollection DhcpServerAddresses { get; }

member this.DhcpServerAddresses : System.Net.NetworkInformation.IPAddressCollection

Public MustOverride ReadOnly Property DhcpServerAddresses As IPAddressCollection

属性值

一个 IPAddressCollection 包含 DHCP 服务器的地址信息，如果未找到任何服务器，则包含空数组。

示例

下面的代码示例显示本地计算机上的网络接口的 DHCP 地址信息。

public static void DisplayDhcpServerAddresses()
{
    Console.WriteLine("DHCP Servers");
    NetworkInterface[] adapters  = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in adapters)
    {

        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
        IPAddressCollection addresses = adapterProperties.DhcpServerAddresses;
        if (addresses.Count >0)
        {
            Console.WriteLine(adapter.Description);
            foreach (IPAddress address in addresses)
            {
                Console.WriteLine("  Dhcp Address ............................ : {0}",
                    address.ToString());
            }
            Console.WriteLine();
        }
    }
}

Public Shared Sub DisplayDhcpServerAddresses() 
    Console.WriteLine("DHCP Servers")
    Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
    Dim adapter As NetworkInterface
    For Each adapter In  adapters
        
        Dim adapterProperties As IPInterfaceProperties = adapter.GetIPProperties()
        Dim addresses As IPAddressCollection = adapterProperties.DhcpServerAddresses
        If addresses.Count > 0 Then
            Console.WriteLine(adapter.Description)
            Dim address As IPAddress
            For Each address In  addresses
                Console.WriteLine("  Dhcp Address ............................ : {0}", address.ToString())
            Next address
            Console.WriteLine()
        End If
    Next adapter

End Sub

注解

动态主机配置协议（DHCP）允许计算机从 DHCP 服务器获取网络地址，而不是使用静态（固定）网络地址。 DHCP 服务器不会永久分配地址;而是暂时使用计算机中的一个可用地址。
