Question

Writing my first silverlight application.

I need to deliver some bitmap that the customer will choose ( used OpenFileDialog ) to the server side ( using web service ).

After the customer choosing the bitmap – i cant access the file and break hit to byte array because i dont see the file full path on the OpenFileDialog object properties.

How can i do it ?

( i have method that get Bitmap and return the bitmap as byte array )

Answer 1

I did that before, here is part of it:

OpenFileDialog dialog = new OpenFileDialog();
dialog.Filter = "Images (*.png; *.jpg)| *.png; *.jpg";
dialog.Multiselect = false;
if (dialog.ShowDialog() == true)
{
  using (System.IO.Stream stream = dialog.File.OpenRead())
  {
    BinaryReader binaryReader = new BinaryReader(stream);
    // here are the bytes you want, put them somewhere to send them to the server
    byte[] imageBytes = binaryReader.ReadBytes((int)stream.Length);

    // here is the filename if you need it
    string filename = System.IO.Path.GetFileNameWithoutExtension(dialog.File.Name);
    stream.Close();
  }
}
