示例
以下示例显示本地计算机上所有接口的类型信息。
void DisplayTypeAndAddress()
{
IPGlobalProperties ^ computerProperties = IPGlobalProperties::GetIPGlobalProperties();
array<NetworkInterface^>^nics = NetworkInterface::GetAllNetworkInterfaces();
Console::WriteLine( "Interface information for {0}.{1} ", computerProperties->HostName, computerProperties->DomainName );
System::Collections::IEnumerator^ myEnum27 = nics->GetEnumerator();
while ( myEnum27->MoveNext() )
{
NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum27->Current);
IPInterfaceProperties ^ properties = adapter->GetIPProperties();
Console::WriteLine( adapter->Description );
Console::WriteLine( String::Empty->PadLeft( adapter->Description->Length, '=' ) );
Console::WriteLine( " Interface type .......................... : {0}",
adapter->NetworkInterfaceType );
Console::WriteLine( " Physical Address ........................ : {0}",
adapter->GetPhysicalAddress() );
Console::WriteLine( " Is receive only.......................... : {0}",
adapter->IsReceiveOnly );
Console::WriteLine( " Multicast................................ : {0}",
adapter->SupportsMulticast );
}
}
public static void DisplayTypeAndAddress()
{
IPGlobalProperties computerProperties = IPGlobalProperties.GetIPGlobalProperties();
NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();

注解
枚举文档中详细介绍 System.Net.NetworkInformation.NetworkInterfaceType 了接口类型。
原则上,此属性可以返回 枚举的任何成员 NetworkInterfaceType 。 它返回的特定值取决于基础网络拓扑的运行时条件。 这意味着:
无法提前确定属性为特定网络返回哪个值。
实际上,在特定网络上,枚举值的完整范围可能不可用。 例如,在千兆位以太网网络上,属性可能返回 NetworkInterfaceType.Ethernet 而不是 NetworkInterfaceType.GigabitEthernet。
