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。
