Hello everyone,
In the form I have comboBox1, when I click on comboBox1 then selects a network adapter and it works.

I would like to:
when I select a network adapter, as a result in the "Label1.Text" will be:
Wi-Fi or Ethernet.
Code that has so far is below (and it works).
Please Help. Thank you.

What I have tried:

private void Form1_Load(object sender, EventArgs e)
       {
           ManagementObjectSearcher mos = new ManagementObjectSearcher("select * from Win32_NetworkAdapter Where AdapterType='Ethernet 802.3'");
           foreach (ManagementObject mo in mos.Get())
           {
               comboBox1.Items.Add(mo["Name"].ToString());
           }

       }

Solution 1

Try the NetworkInterfaceType property:

foreach (NetworkInterface ni in NetworkInterface.GetAllNetworkInterfaces())
    {
    if (ni.OperationalStatus == OperationalStatus.Up)
        {
        Console.WriteLine(ni.NetworkInterfaceType.ToString());
        }
    }

Thanks, but this code detects the type of network adapter that is active, and I want to detect the type of network adapter what I select it.
example:
If you have two adapters (Wi-Fi and Ethernet), and Wi-Fi is active and the Ethernet is not active, and if I select Ethernet to get the result = Wireless80211.
or 
if the active Ethernet and Wi-Fi is not active, and I select Wi-Fi as a result get = Ethernet.
