P2PActivity (Games)

FooGame Application

First, design a class extends P2PApplication. Pass your App-GUID and App-ID to P2PApplicationAttribute.

[P2PApplication(APP_ID, "APP-GUID")]
public class FooGameApplication : P2PApplication
{
}

P2PApplication.AddApplication(Assembly assembly); // All applications in your dll
P2PApplication.AddApplication(typeof(FooGameApplication)); // One type

Override properties and methods.

public override string InvitationContext
{
    get
    {
        string activityUrl = AppID + ";1;FooGame";
        byte[] contextData = System.Text.UnicodeEncoding.Unicode.GetBytes(activityUrl);
        return Convert.ToBase64String(contextData, 0, contextData.Length);
    }
}

public override bool AutoAccept
{
    get
    {
        return true;
    }
}


public override bool ValidateInvitation(SLPMessage invitation)
{
    return base.ValidateInvitation(invitation);
}


public override void HandleMessage(IMessageProcessor sender, P2PMessage p2pMessage)
{
    // Handle p2pMessage
    string incomingXml = Encoding.UTF8.GetString(p2pMessage.InnerBody);

    // And send the data
    P2PDataMessage p2pData = new P2PDataMessage();
    p2pData.InnerBody = data; // xml data
    SendMessage(p2pData);
}

Constructors

// We have received an invitation
public P2PObjectTransferApplication(P2PSession session)
    : base(session)
{
    SLPMessage slp = session.Invite;
}

// We are initializer 
public P2PObjectTransferApplication(Contact remote)
    : base(contact)
{
}
