Voorbeelden

De volgende voorbeeldcode illustreert hoe u een PeerNearMe opsomming maakt en deze toevoegt als een PeerContact aan de lokale ContactManager:

// Displays all contacts and asssociated peer endpoints (PeerEndPoint) in the PeerContactCollection.
private static void DisplayContacts(PeerContactCollection peerContactsCollection)
{
    if (peerContactsCollection == null ||
        peerContactsCollection.Count == 0)
    {
        Console.WriteLine("No contacts to display. To add a contact select option 0 from the menu.");
    }
    else
    {
        foreach (PeerContact pc in peerContactsCollection)
        {
            Console.WriteLine("The contact is: {0}", pc.DisplayName);
            DisplayEndpoints(pc.PeerEndPoints);
        }
    }
    return;
}

//------------------------------------------------------------------------------------------------------
//------------------------------------------------------------------------------------------------------
// Displays all peer end points (PeerEndPoint) in the PeerEndPointCollection.

private static void DisplayEndpoints(PeerEndPointCollection endpointCollection)
{
    if (endpointCollection == null ||  endpointCollection.Count == 0)
    {
        Console.WriteLine("No peer endpoints in the collection to display.");
    }
    else
    {
        foreach (PeerEndPoint pep in endpointCollection)
        {
            Console.WriteLine("PeerEndPoint is: {0}", pep);
            Console.WriteLine("PeerEndPoint data is:\n  Name: {0}\n EndPoint IP address: {1}\n . Port: {2}\n",
                pep.Name,
                pep.EndPoint.Address,
                pep.EndPoint.Port);
