xamarin.forms - How can I databind an image?

Question

How can I databind an image using XAML?

Specifically, I have a stream object that I would like to convert into an image.

However, I just cannot find a basic example of how to do this.

1. What does the viewmodel property look like?

• Do I use an ImageSource?

• Do I need a value converter?

2. What does the XAML look like?

Answer 1

Forms has a StreamImageSource you can use to do this. However, I don't think you can use it in XAML without writing a custom converter. To use it in code, you would do something like this:

image1.Source = ImageSource.FromStream(() =>
{
  // whatever you need to do to create your stream
  return stream;
});
