convert image into base64 in wp8

Question

I have an image taken from my phone gallery, like below:

private void StackPanel_Tap_1(object sender, System.Windows.Input.GestureEventArgs e)
{
    PhotoChooser         


        

Answer 1

Simply convert the byte[] to a base64 string:

byte[] bytearray = null;

using (MemoryStream ms = new MemoryStream())
{
    if (imgphotochoser.Source != null)
    {
        WriteableBitmap wbitmp = new WriteableBitmap((BitmapImage)imgphotochoser.Source);

        wbitmp.SaveJpeg(ms, 46, 38, 0, 100);
        bytearray = ms.ToArray();
    }
}
string str = Convert.ToBase64String(bytearray);

Base64 to byte[]:

byte[] fileBytes = Convert.FromBase64String(s);

using (MemoryStream ms = new MemoryStream(fileBytes, 0, fileBytes.Length))
{
    ms.Write(fileBytes, 0, fileBytes.Length);
    BitmapImage bitmapImage = new BitmapImage();
    bitmapImage.SetSource(ms);
    return bitmapImage;
}
