Google.Cloud.Dialogflow.V2 WebHook response card

Hello,

I’m using the Nuget package (.NET): Google.Cloud.Dialogflow.V2 (1.0.0-beta01) This code is a simple example of what I’m trying to do:

 [System.Web.Mvc.HttpPost]
        public WebhookResponse Webhook(WebhookRequest request)
        {
            var message = new Intent.Types.Message
            {
                Card = new Intent.Types.Message.Types.Card
                {
                    Title = "Oh Yeah !",
                    ImageUri = "https://www.google.be/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png"
                }
            };
            return new WebhookResponse
            {
                FulfillmentMessages = new Google.Protobuf.Collections.RepeatedField<Intent.Types.Message>
                {
                    message
                },
                FulfillmentText = request.QueryResult.FulfillmentText,
                Source = ""
            };
        }

But this code is not working as FulfillmentMessages is read-only. Only get is available from WebhookResponse:

//
        // Summary:
        //     Optional. The collection of rich messages to present to the user. This value
        //     is passed directly to `QueryResult.fulfillment_messages`.
        [DebuggerNonUserCode]
        public RepeatedField<Intent.Types.Message> FulfillmentMessages { get; }

So my question is: How can I send something else that just text from my WebHook ?

Ah, I see. Sorry for misreading the question before. It’s a read-only property, but you just add values to it. All you need to do is get rid of the “new …” part and you can use the collection initializer:

return new WebhookResponse
{
    FulfillmentMessages = { message },
    FulfillmentText = request.QueryResult.FulfillmentText,
    Source = ""
};

Note that RepeatedField<T> has an overload accepting IEnumerable<T> as well, so it’s easy to populate with a LINQ query.
