Get ConversationId from Context

问题

How can I get the ConversationId from the IDialogContext context? I know that there is a ConverationData property but that seems to just be a data bag that can hold anything.

Is the id in this bag? If so, what is the key to retrieve it?

public async Task General(IDialogContext context, LuisResult result)
{
    //how can I access the conversationId here
}

So I have found a way of doing it but I am not sure if it is the best way.

The context object that is passed in has a data field on it which contains the original message object which in turn contains the ConversationId. Unfortuantely this is private.

But the context does have a CreateMessage method which returns a Message object which contains the ConversationId and it is accessible.

var id = context.MakeMessage().ConversationId;

Like I said, I am not sure if this is the best way but it is the only way I have been able to achieve this. I'll leave this up in case someone has a better way.

Have a look at this code:

var id = context.MakeMessage().Conversation.Id;

Id is now property in Conversation object. It works for me.

With the last version of the framework you can get it from the DialogContext object easier:

var conversationId = context.Activity.Conversation.Id;

I used it and it worked on my bot.
