Examples
The following code example displays Domain Name Service (DNS) configuration information for the local computer's network adapters.
void DisplayDnsConfiguration()
{
array<NetworkInterface^>^adapters = NetworkInterface::GetAllNetworkInterfaces();
System::Collections::IEnumerator^ myEnum10 = adapters->GetEnumerator();
while ( myEnum10->MoveNext() )
{
NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum10->Current);
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 );
}
}
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
Remarks
The network interfaces on a computer provide network connectivity. Network interfaces are also known as network adapters.
