Question

How do I get image from http url, my url is like:
"http://accd.com/abc.htm",
how do I get image from it?

Answer 1

So
public static BitmapImage Base64StringToBitmap(string source)
{
var ims = new InMemoryRandomAccessStream();
var bytes = Convert.FromBase64String(source);
var dataWriter = new DataWriter(ims);
dataWriter.WriteBytes(bytes);
dataWriter.StoreAsync();
ims.Seek(0);
var img = new BitmapImage();
img.SetSource(ims);
return img;
}

Answer 2

You can use the web client like this :
var webClient = new WebClient();
webClient.DownloadStringAsync(new Uri("http://accd.com/abc.htm"));
webClient.DownloadStringCompleted += (sender, eventArgs) => (eventArgs.Result); //Here is your base 64 image code, you can use the Base64StringToBitmap function

Answer 3

May be with using a webclient
WebClient wc = new WebClient();
wc.OpenReadCompleted += new OpenReadCompletedEventHandler(wc_OpenReadCompleted);
wc.OpenReadAsync(new Uri("your http url"), wc);
void wc_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
{
try
{
BitmapImage bitmapImage = new BitmapImage();
bitmapImage.SetSource(e.Result);
imgLogoData.Source = bitmapImage;
imgLogoData.Height = 200;
}
catch (Exception ex)
{
MessageBox.Show(AppResources.resErrorOccured);
ExceptionHelper.WriteLog(ex);
}
}
And to convert a Base64 string to BitmapImage just follow this method
public static BitmapImage base64image(string base64string)
{
byte[] fileBytes = Convert.FromBase64String(base64string);
using (MemoryStream ms = new MemoryStream(fileBytes, 0, fileBytes.Length))
{
ms.Write(fileBytes, 0, fileBytes.Length);
BitmapImage bitmapImage = new BitmapImage();
bitmapImage.SetSource(ms);
return bitmapImage;
}
}
So that, for an Image declared in xaml like this
Add an image to your XAML, such as this:
<Image x:Name="imgLogoData" Height="50" Width="50" />
You can then set the source, like this:
imgLogoData.Source = base64image(yourBase64string);
