Xamarin蓝牙扫描

Question

today i started developing with C# and i tried to scan for a beacon. This is how far i came..

        protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);            
        // Set our view from the "main" layout resource
        SetContentView(Resource.Layout.Main);

        BluetoothAdapter oBluetoothAdapter = BluetoothAdapter.DefaultAdapter;
        BluetoothLeScanner oScanner = oBluetoothAdapter.BluetoothLeScanner;

        ScanCallback oCallback;



        if(!oBluetoothAdapter.IsEnabled)
        {
            StartActivity(new Intent(BluetoothAdapter.ActionRequestEnable));
        } 
        else
        {
            oScanner.StartScan(oCallback);
        }
    }

The Problem is that i dont know how to use the Callback Parameter of the StartScan function. Can sombody please tell me how to use the callback right ?

On android the implementation would be something like this:

_Manager = (BluetoothManager)appContext.GetSystemService("bluetooth");
_Adapter = _Manager.Adapter;
_LeScanner = _Adapter.BluetoothLeScanner;
 _BluetoothScanCallback = new BluetoothScanCallback();

Then when you start your scan it would be something like this:

_LeScanner.StartScan(_BluetoothScanCallback);

where BluetoothScanCallback would be implemented using something like:

public class BluetoothScanCallback : ScanCallback
{
    public override void OnScanResult([GeneratedEnum] ScanCallbackType callbackType, ScanResult result)
    {
        base.OnScanResult(callbackType, result);
    }
}
