Question

i am trying to work with wifi networks. for that i am using WiFiAdapter but i cannot create it's instance as it says that this doesnot have construtor of x parameters. then i tried to scan networks and store it in wifinetworkreport but it's giving the same problem.

What I have tried:

WiFiNetworkReport networkReport; ;
networkReport = wiFiAdapter.NetworkReport;
IReadOnlyList<WiFiAvailableNetwork> readOnlyList = new List<WiFiAvailableNetwork>();
readOnlyList = networkReport.AvailableNetworks;

but this is giving Null pointer. so how can get the networks fro this class or create an instance of the classes that dont have constructors. dont they have default constructors?

You need to show more code ... like what you've been doing with / to (local) "wifiAdapter".

Solution 1

Yes, u can't create an instance of this class.
You need to use, for example, the following:

C#

WiFiAdapter wiFiAdapter = WiFiAdapter.FindAllAdaptersAsync().GetResults().First();

- Get all WiFi-Adapter of the system
- Get the first one which is a instance of a WiFiAdapter

Or you could use this approach to iterate through each adapter and perform a specific action:

C#

private async void WiFiAdapterSample()
        {
            var systemsWiFiAdapter = await WiFiAdapter.FindAllAdaptersAsync();
            foreach (var wifiAdapter in systemsWiFiAdapter)
            {
                // do something
            }
        }

this code is generating error msg of that it(returning type) doesnot contain definition for 'getawaiter' etc.

i have done it by a bad way but however that's working. my code is


var list = WiFiAdapter.FindAllAdaptersAsync();
Thread.Sleep(timeout);

it's working fine so far although it's not a good way

Sure.
As async method is used u need to use the await keyword as posted in the second code example working with the foreach loop.
Your code using Thread.Sleep is bad style to achive this.

When i do "var adapters = await WiFiAdapter.FindAllAdaptersAsync();" multiple times I get the following error: "An attempt was made to establish a session to a network server, but there are already too many sessions established to that server. (Exception from HRESULT: 0x800704C4)". Any idea how i can avoid this error? I need to scan multiple times (making a wifi heatmapper application).
