Unable to Import Annotations

[John]

I am working on a project where annotations need to be imported and exported. I am able to export the annotations just fine like this:

        using var stream = await pdfViewer.ExportAnnotationAsStream();

        using var sr = new StreamReader(stream);

        selectedAnnotation.Json = sr.ReadToEnd();

However, when I import them, nothing happens. I don't see any errors and the rendered document stays the same. Here is my code for importing:

            using var ms = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(selectedAnnotation.Json));

            await pdfViewer.ImportAnnotation(ms);

The example provided in the documentation uses a string to load a network resource. How should I be importing? 

Thank you,

John

You are right. The annotations were loading; however they didn't seem to appear because the previous annotation was still there. By using await PDFViewer.DeleteAnnotations(); I was able to clear those.

Thank you,
