Get SSID of the wireless network I am connected to with C# .Net on Windows Vista

Question

I'd like to know if there is any .Net class that allows me to know the SSID of the wireless network I'm connected to. So far I only found the library linked below. Is the best I can get or should I use something else? Managed WiFi (http://www.codeplex.com/managedwifi)

The method that exploits WMI works for Windows XP but is it not working anymore with Windows Vista.

Answer 1

I resolved using the library. It resulted to be quite easy to work with the classes provided:

First I had to create a WlanClient object

wlan = new WlanClient(); 

And then I can get the list of the SSIDs the PC is connected to with this code:

Collection<String> connectedSsids = new Collection<string>();  foreach (WlanClient.WlanInterface wlanInterface in wlan.Interfaces) {    Wlan.Dot11Ssid ssid = wlanInterface.CurrentConnection.wlanAssociationAttributes.dot11Ssid;    connectedSsids.Add(new String(Encoding.ASCII.GetChars(ssid.SSID,0, (int)ssid.SSIDLength))); } 

Answer 2

We were using the managed wifi library, but it throws exceptions if the network is disconnected during a query.

Try:

var process = new Process {     StartInfo =     {     FileName = "netsh.exe",     Arguments = "wlan show interfaces",     UseShellExecute = false,     RedirectStandardOutput = true,     CreateNoWindow = true     } }; process.Start();  var output = process.StandardOutput.ReadToEnd(); var line = output.Split(new[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries).FirstOrDefault(l => l.Contains("SSID") && !l.Contains("BSSID")); if (line == null) {     return string.Empty; } var ssid = line.Split(new[] { ":" }, StringSplitOptions.RemoveEmptyEntries)[1].TrimStart(); return ssid;
