UWP equivalent of Android's SpannableString with image inside

Hello,

Welcome to Microsoft Q&A.

in UWP, RichTextBlock is needed for image and text mixing.

With Xaml

<RichTextBlock>
    <Paragraph>
        <Run Text="Something..."/>
        <InlineUIContainer>
            <Image Source="your_image_url" Width="20" Height="20"/>
        </InlineUIContainer>
        <Run Text="Something..."/>
    </Paragraph>
</RichTextBlock>

With Code

var richTextBlock = new RichTextBlock();
var para = new Paragraph();
para.Inlines.Add(new Run() { Text = "Something..." });
var imgContainer = new InlineUIContainer();
var img = new Image();
img.Source = new BitmapImage(new Uri("your_image_url"));
imgContainer.Child = img;
para.Inlines.Add(imgContainer);
para.Inlines.Add(new Run() { Text = "Something..." });
richTextBlock.Blocks.Add(para);

Or you could write it this way, which more closely mirrors the XAML.

var richTextBlock = new RichTextBlock()
{
    Blocks = {
        new Paragraph {
            Inlines = {
                new Run { Text = "Something" },
                new InlineUIContainer {
                    Child = new Image {
                        Source = new BitmapImage(new Uri("your_image_url"))
                    }
                },
                new Run { Text = "Something..."}
            }
        }
    }
};

Thanks.
