NetworkInterface.GetAllNetworkInterfaces 方法

定义

返回描述本地计算机上的网络接口的对象。

public:
 static cli::array <System::Net::NetworkInformation::NetworkInterface ^> ^ GetAllNetworkInterfaces();
[System.Runtime.Versioning.UnsupportedOSPlatform("illumos")]
[System.Runtime.Versioning.UnsupportedOSPlatform("solaris")]
public static System.Net.NetworkInformation.NetworkInterface[] GetAllNetworkInterfaces();
public static System.Net.NetworkInformation.NetworkInterface[] GetAllNetworkInterfaces();
[<System.Runtime.Versioning.UnsupportedOSPlatform("illumos")>]
[<System.Runtime.Versioning.UnsupportedOSPlatform("solaris")>]
static member GetAllNetworkInterfaces : unit -> System.Net.NetworkInformation.NetworkInterface[]
static member GetAllNetworkInterfaces : unit -> System.Net.NetworkInformation.NetworkInterface[]
Public Shared Function GetAllNetworkInterfaces () As NetworkInterface()

返回

一个 NetworkInterface 数组,其中包含描述可用网络接口的对象,如果没有检测到接口,则为空数组。

属性

例外

Windows 系统函数调用失败。

示例

下面的代码示例显示域名服务 (DNS) 本地计算机的网络适配器的配置信息。

public static void DisplayDnsConfiguration()
{
    NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in adapters)
    {
        IPInterfaceProperties properties = adapter.GetIPProperties();
        Console.WriteLine(adapter.Description);
        Console.WriteLine("  DNS suffix .............................. : {0}",
            properties.DnsSuffix);
        Console.WriteLine("  DNS enabled ............................. : {0}",
            properties.IsDnsEnabled);
        Console.WriteLine("  Dynamically configured DNS .............. : {0}",
            properties.IsDynamicDnsEnabled);
    }
    Console.WriteLine();
}
Public Shared Sub DisplayDnsConfiguration() 
    Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
    Dim adapter As NetworkInterface
    For Each adapter In  adapters
        Dim properties As IPInterfaceProperties = adapter.GetIPProperties()
        Console.WriteLine(adapter.Description)
        Console.WriteLine("  DNS suffix................................. :{0}", properties.DnsSuffix)
        Console.WriteLine("  DNS enabled ............................. : {0}", properties.IsDnsEnabled)
        Console.WriteLine("  Dynamically configured DNS .............. : {0}", properties.IsDynamicDnsEnabled)
    Next adapter

End Sub

注解

计算机上的网络接口提供网络连接。 网络接口也称为网络适配器。
