Byte Image data as URL in BotFramework

Question

I am building on bot application where i need to show images in Carousel, I am using Hero card. In this card i need to show image which i am getting from API, image data is in byte format and in herocard it is asking for URI cant we pass byte data in Herocard?

  allAttachements.Add(new HeroCard
            {
                Title = "test" ,
                Subtitle = "SubTitle",
                Text = "Details",
                Images = new List<CardImage> { new CardImage(url) },
            })
             }.ToAttachment()

            );

I tried with below line but it wont work.

string url = $"data:image/png;base64,{ImageData}";

Appreciate your help in advance.

It was my bad i was passing "data:image/png;base64", 2 times thats why image is not showing, now image is visible. — Riyaj Shaikh, Sep 12 '17 at 17:25

Please try this:

reply.Attachments.Add(new Attachment()
{
     ContentUrl = $"data:image/jpeg;base64,{Convert.ToBase64String(candidate.ImageData)}"
})

Hey @JasonSowers, i have Multiple Herocards and i am passing multiple cards as attachment hero card – Riyaj Shaikh Sep 11 '17 at 18:25
@EzequielJadib didn't know that existed. You should be able to repurpose this code, or the code in Ezequiel's duplicate for your needs. really all that is missing is the `Convert.ToBase64String(candidate.ImageData)` – D4RKCIDE Sep 11 '17 at 18:31
