示例
下面的示例代码演示如何枚举 PeerNearMe ,并将其作为添加 PeerContact 到本地 ContactManager :The following example code illustrates how to enumerate a PeerNearMe and add it as a PeerContact to the local 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);
}
}
return;
}
//------------------------------------------------------------------------------------------------------
//------------------------------------------------------------------------------------------------------
//List PeerNearMe objects that may be added as contacts.
private static void AddContact()
{
PeerNearMeCollection pnmc = null;
PeerContactCollection peerContacts = null;
bool peerNameFound = false;
PeerApplication application = null;
try
{
Console.WriteLine("Listing the existing contacts...");
peerContacts = PeerCollaboration.ContactManager.GetContacts();

}
catch (Exception ex)

Console.WriteLine("An unexpected error occurred while attempting to obtain the contact list: {0}", ex.Message);
}
DisplayContacts(peerContacts);
try
{
//Adds one of the PeerNearMe objects as a contact.
pnmc = GetPeersNearMe();
Console.WriteLine("Please enter the nickname of the peer you wish to add as a contact:");
string peerNameToAdd = Console.ReadLine();
application = RegisterCollabApp();
foreach (PeerNearMe pnm in pnmc)

}
else
{
Console.WriteLine("This peer already exists in your contact list.");
Console.WriteLine("Sending invitation using the Contact structure instead of the PeerNearMe.");
foreach (PeerContact pc in peerContacts)
{
if (pc.Nickname.Equals(pnm.Nickname))
{
res = pnm.Invite(application, "Peer Collaboration Sample", application.Data);
if (res.PeerInvitationResponseType == PeerInvitationResponseType.Accepted)
{
Console.WriteLine("Invitation to contact succeeded.");
}
else
{
Console.WriteLine("Invitation to contact {0}.", res.PeerInvitationResponseType);
}
}
}
}
}
}
if (!peerNameFound)
{
Console.WriteLine("No such peer exists near you. Cannot add to contacts.");
return;
}
peerContacts = PeerCollaboration.ContactManager.GetContacts();
Console.WriteLine("Listing the contacts again...");
DisplayContacts(peerContacts);
}
catch (Exception ex)
{
Console.WriteLine("Error adding a contact: {0}", ex.Message);
}
finally
{
application.Dispose();
}
return;
