如何使用UCMA 4.0连接到Lync服务器

我有一个项目，我必须创建简单的Web表单，因为会有一个按钮，当用户按下按钮时，应用程序应联系Lync服务器以设置Web会议（在线会议）。 br />


此外，应用程序应将结果呈现给用户，并且最好显示用户可以使用Lync参与在线会议的链接



我读了所有细节，但仍然不知道从哪里开始，我读到有关UCMA 4.0 sdk，安装它，添加 Microsoft.Rtc.Collaboration dll ，但直到我不知道使用哪个类和调用哪个类方法，连接到服务器我什么都做不了。任何人都可以通过这个，代码或任何文章解释如何使用这个SDK。



我发现这很有用，因为从这里读取，至少我能够理解并编写一些代码。但是问题还没有解决

I have a project in which i have to create simple web form, in that there will be a button, When user will press button, the application should contact Lync server to set up a web conference (an online meeting).

Also, The application should present the result to the user, and preferable display a link which the user can click on to participate in the online meeting using Lync

I read all details, but still don't know from where to start, I read about UCMA 4.0 sdk, installed it, added Microsoft.Rtc.Collaboration dll, but until i don't know which classes are used and which class method to call, to connect to server i cant do anything. Anyone can help through this, with code or any article explaining how to use this SDK.

I found this useful, because reading from this, at least i am able to understand and write some code. but issue is not resolved yet

private void button1_Click(object sender, EventArgs e)
{
    ConferenceScheduleInformation CSI = new ConferenceScheduleInformation();
     
    CSI.AccessLevel = ConferenceAccessLevel.Everyone;
    CSI.AutomaticLeaderAssignment = AutomaticLeaderAssignment.Everyone;
    CSI.ConferenceId = "Whatever";
    CSI.Description = "Test Conference";
    CSI.Subject = "Testing_Subject";
    CSI.Mcus.Add(new ConferenceMcuInformation(McuType.AudioVideo));
        
    try
    {
        _localendpoint.ConferenceServices.BeginScheduleConference(CSI,
            ar =>
            {
                try
                {
                    Conference newConference = _localendpoint.ConferenceServices.EndScheduleConference(ar);
                    //DoSomethingWithTheConference(newConference);
                }
                catch (RealTimeException ex)
                {
                    Console.WriteLine(ex);
                }
            },
            null);
    }
    catch (InvalidOperationException ex)
    {
        Console.WriteLine(ex);
    }
}

我在这里得到Null参考例外
会议newConference
，如何为了解决这个问题，我犯了什么错误？

I Am getting Null reference exception here
Conference newConference
, How to solve this, What mistake i am making??
