返回新的來電uri

Question

我正在使用此簡單的代碼來獲取來電和呼叫者的Uri。 如果用戶有多個Lync會話打開，則由於靜態索引，它總是返回第一個。 我如何能夠獲得新的連接索引，以便獲得正確的呼叫者uri？

    Imports Microsoft.Lync.Model
Imports Microsoft.Lync.Model.Conversation
Imports Lync = Microsoft.Lync.Model.Conversation


Public Class myLync
    Private _LyncClient As LyncClient
    Public WithEvents _ConversationMgr As Microsoft.Lync.Model.Conversation.ConversationManager
    Public WithEvents _conv As Conversation

 Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Try
            _LyncClient = LyncClient.GetClient()
            _ConversationMgr = _LyncClient.ConversationManager
        Catch ex As Exception
        End Try
 End Sub

 Private Sub _ConversationMgr_ConversationAdded(ByVal sender As Object, ByVal e As Microsoft.Lync.Model.Conversation.ConversationManagerEventArgs) Handles _ConversationMgr.ConversationAdded
        AddHandler e.Conversation.Modalities(ModalityTypes.AudioVideo).ModalityStateChanged, AddressOf AVModalityStateChanged
 End Sub

 Private Sub AVModalityStateChanged(ByVal sender As Object, ByVal e As ModalityStateChangedEventArgs)
        Select Case e.NewState
            Case ModalityState.Notified
                Dim Uri = _ConversationMgr.Conversations.Item(0).Participants.Item(1).Contact.Uri
        End Select
 End Sub

Answer 1

在AVModalityStateChanged(ByVal sender As Object, ByVal e As ModalityStateChangedEventArgs) ，可以將sender參數AVModality轉換為AVModality類型，從那里您可以訪問參與者。

不好意思，我的C＃看起來像：

  private void Participant_ModalityStateChanged(object sender, ModalityStateChangedEventArgs e)
    {
        if (e.NewState == ModalityState.Connected)
        {
            var modality = (AVModality) sender;
            var participant = modality.Participant;
            var uri = participant.Contact.Uri;
        }
    }
