lync - 有人共享相机时的全屏对话

Question

当有人分享它的相机时，我试图将对话置于全屏模式，但我不知道我应该订阅哪个事件处理程序。现在我订阅了这个事件处理程序：

AVModality.StreamStateChanged += AV_StreamStateChanged;
AVModality.ModalityStateChanged += AVModality_ModalityStateChanged;
VideoChannel.StateChanged += VideoChannel_StateChanged;

Answer 1

尝试VideoChannel.StateChanged事件。本次活动正在Conversation.ParticipantAdded活动中。

this.Conversation.PaticipantAdded += this.Conversation_ParticipantAdded;

private void Conversation_ParticipantAdded(object sender, ParticipantCollectionChangedEventArgs e) {
    if (e.Participant.IsSelf) {
    }
    else {
      var avModality = e.Participant.Modalities[ModalityTypes.AudioVideo] as AVModality;
      avModality.VideoChannel.StateChanged += this.ClientParticipant_VideoChannel_StateChanged;
    }
}

private void ClientParticipant_VideoChannel_StateChanged(object sender, ChannelStateChangedEventArgs e) {
 //Look for e.NewState
}

e.NewState可用于监听 channelstate 枚举。可以在此处找到枚举的详细信息。

也看看这个链接。它使用 Lync SDK 2010，但看起来仍然非常相关。
