C#

using System.Drawing;

namespace Photo
{
   public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

           
            string filename1 = @"C:\images\mainicon.jpg";
            Image image1 = Image.FromFile(filename1);
        }
    }
}

I am using .net framework wcf client and server . The signature of the WCF service interface is simple:

ResponseMessage SendMessage(RequestMessage message)

I create a new type that inherits from "ResponseMessage". This type holds 1 property:


public class TestResponseMessage : ResponseMessage
{
        public List<ISomeInterface> Members { get; set; }
}

According to:

It is said that "Members" property should be able to serialize without the need of the [DataContract] on the class and [DataMember] on the property, but it doesn't work - if I don't use it, I get null in the TestResponse.

The reason for asking this is that we've encountered a very strange behavior in our product - sometimes this serialization works and sometimes it doesn't, and it seems to behave differently with same client/server versions on different machines.

Any insights about this will be very welcome.

byte[] rawData = new byte[0];
rawData = (byte[])sql_reader["photo"];
int len = new int();
len = rawData.GetUpperBound(0);
FileStream fs = new FileStream(photo_file, FileMode.OpenOrCreate, FileAccess.Write);
fs.Write(rawData, 0, len);
fs.Close();
curImage = Image.FromFile(photo_file);
pictureEmployee.Image = curImage;
