public abstract OperationalStatus OperationalStatus { get; }

The operational status values are described in detail in the OperationalStatus enumeration documentation.

The following code example displays a summary for all interfaces on the local computer.


public static void ShowInterfaceSummary()
{

    NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in interfaces)
    {                
        Console.WriteLine ("Name: {0}", adapter.Name);
        Console.WriteLine(adapter.Description);
        Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length,'='));
        Console.WriteLine("  Interface type .......................... : {0}", adapter.NetworkInterfaceType);
        Console.WriteLine("  Operational status ...................... : {0}", 
            adapter.OperationalStatus);
        string versions ="";

        // Create a display string for the supported IP versions.
        if (adapter.Supports(NetworkInterfaceComponent.IPv4))
        {
             versions = "IPv4";
         }
        if (adapter.Supports(NetworkInterfaceComponent.IPv6))
        {
            if (versions.Length > 0)
            {
                versions += " ";
             }
            versions += "IPv6";
        }
        Console.WriteLine("  IP version .............................. : {0}", versions);
        Console.WriteLine();
    }
    Console.WriteLine();
}
