从C# Asp.net向Lync发送消息

using Microsoft.Lync.Model;
using Microsoft.Lync.Model.Conversation;

// 创建Lync客户端实例
LyncClient lyncClient = LyncClient.GetClient();

// 获取当前用户的通讯终端
var endpoint = lyncClient.Self.Contact.GetContactInformation(ContactInformationType.ContactEndpoints) as List<object>;

// 获取Lync的聊天会话
var conversation = lyncClient.ConversationManager.AddConversation();

// 添加参与者
var participant = conversation.AddParticipant(endpoint[0] as ContactEndpoint);

// 发送消息
InstantMessageModality imModality = conversation.Modalities[ModalityTypes.InstantMessage] as InstantMessageModality;
imModality.BeginSendMessage("Hello, Lync!", null, null);
