LYNC应用程序共享（桌面共享）_conversation.Modalities [ModalityTypes.ApplicationSharing]返回null [英] LYNC APPLICATION SHARING (DESKTOP SHARING) _conversation.Modalities[ModalityTypes.ApplicationSharing] returns null

问题描述

                   点击按钮 应为活动对话窗口触发桌面共享事件。点击按钮，我们有以下代码

           private void StartSharingResource_Button_Click（object sender，EventArgs e）

        {  

            //如果没有活动对话来共享此资源，请从处理程序返回

             if（_conversation == null）

            {

                返回;

            }  

            //如果活动对话中没有本地存储的共享模式，请从活动对话中获取并存储它。

            if（_sharingModality == null）

             {

                  _sharingModality =
_ conversation.Modalities [ModalityTypes.ApplicationSharing] as ApplicationSharingModality ;

            }

 

        } 

 

         关于对话即使我们正在提取对话模式

 

void ConversationManager_ConversationAdded（object sender，Microsoft.Lync.Model.Conversation.ConversationManagerEventArgs e）

        {

          _sharingModality =（ApplicationSharingModality ）_ conversation.Modalities [ModalityTypes.ApplicationSharing] ;  

}  

         在
_ conversation.Modalities [ModalityTypes.ApplicationSharing] 部分中，它都是null，我们得到一个对象引用错误。我们正在使用LYNC SDK - 15.0.4603.1000版本。

解决方案

应用程序共享是否在SDK之外工作？

                   On the click of a button  the desktop sharing event should be triggered for the active conversation window. In the button click we have the following code

          private void StartSharingResource_Button_Click(object sender, EventArgs e)

        { 

            //If there is no active conversation to share this resource in, return from handler

            if (_conversation == null)

            {

                return;

            } 

            //If there is no sharing modality stored locally on the active conversation, get it from the active conversation and store it.

            if (_sharingModality == null)

            {

                _sharingModality = _conversation.Modalities[ModalityTypes.ApplicationSharing] as ApplicationSharingModality;

            }

 

        }  

 

          On Conversation Added even we are fetching the conversation modality

 

void ConversationManager_ConversationAdded(object sender, Microsoft.Lync.Model.Conversation.ConversationManagerEventArgs e)

        {

          _sharingModality = (ApplicationSharingModality)_conversation.Modalities[ModalityTypes.ApplicationSharing]; 

} 

          In both the section _conversation.Modalities[ModalityTypes.ApplicationSharing] is coming as null and we get an object reference error. We are using LYNC SDK - 15.0.4603.1000 version.

解决方案

Does application sharing work outside of the SDK?
