At which step did you encounter a problem? Could you post more details about the issue?

How did you load the images? You could store the images to the database as a byte[].

public class TodoItem
{
    [PrimaryKey, AutoIncrement]
    public int ID { get; set; }
    public byte[] itemData { get; set; }
}

Download the api to get the byte array and convert it to the ImageSource.

var imageBytes = await downloadImage();
image.Source = ImageSource.FromStream(() => new MemoryStream(imageBytes));

if (!Request.Content.IsMimeMultipartContent())
{
return StatusCode(HttpStatusCode.UnsupportedMediaType);
}
var filesReadToProvider = await Request.Content.ReadAsMultipartAsync();
var jsonkey = await filesReadToProvider.Contents[0].ReadAsStringAsync();
var fileBytes = await filesReadToProvider.Contents[0].ReadAsByteArrayAsync();
var data = jsonkey + fileBytes;
return Ok(data);

What's wrong with the code? Please post details about that.

Breakpoint is not hitting var jsonkey . and when readAsMultipartAsync () its showing error

The breakpoint cannot be hit because of an error in 'readAsMultipartAsync'. What error occured? Please post the error log.
