botframework - Accessing Conversation data from Message Controller c#

Question

I have been using the context.setvalue(); and context.TryGetvalue(); to store and receive data to different storages in Bot Framework.

I want to know how we can access this values from MessageController.cs

Already tried creating a New object, it don't work for me.

I found this post when searching for another answer I posted. I wanted anyone that comes here in the future to know the correct way to do this.

StateClient stateClient = activity.GetStateClient(); gets the Default state client only which is deprecated as of March 31st 2018. It has been replaced by an in-memory state store. If you have implemented your own state client (i.e. cosmosDB, Azure table storage, SQL, etc etc) the proper way to access state in the messages controller is something along the lines of this:

if (activity.Type == ActivityTypes.Message)
{

    var message = activity as IMessageActivity;
    using (var scope = DialogModule.BeginLifetimeScope(Conversation.Container, message))
    {
        var botDataStore = scope.Resolve<IBotDataStore<BotData>>();
        var key = Address.FromActivity(message);

        ConversationReference r = new ConversationReference();
        var userData = await botDataStore.LoadAsync(key, BotStoreType.BotUserData, CancellationToken.None);

        //set state data
        userData.SetProperty("key 1", "value1");
        userData.SetProperty("key 2", "value2");
        //get state data
        userData.GetProperty<string>("key 1");
        userData.GetProperty<string>("key 2");

        await botDataStore.SaveAsync(key, BotStoreType.BotUserData, userData, CancellationToken.None);
        await botDataStore.FlushAsync(key, CancellationToken.None);
    }
    await Conversation.SendAsync(activity, () => new Dialogs.RootDialog());
}
