file upload in silverlight 5 using wcf C#

Step 1) Create Silverlight Project with .Web Option
         i.e SilverlightApplication and SilverlightApplication.Web
Step 2) Add WCF service to SilverlightApplication.Web
 
Interface 
     [ServiceContract]
    public interface IService1
    {
        [OperationContract]
      bool uploads(byte[] bytes, String fileName);
    }

Implementation
public class Service1 : IService1
    {
       

 public bool uploads(byte[] bytes ,String fileName)
        {
            bool b = !true;
            try
            {
                fileName = @"C:\inetpub\wwwroot\SilverlightApplication.Web\Uploads\"+fileName;
                MemoryStream ms = new MemoryStream(bytes);
                StreamReader reader = new StreamReader(ms);
                System.IO.File.WriteAllText(fileName,reader.ReadToEnd());
                b = true;
            }
            catch (Exception ex)
            {
                throw ex;
            }
            return b;
        }    }

make sure permissions for uploads folder

Leave Web.config  settings, because .net 4.0 will take care of it.

Step 3)  Run the Service.
         in my App:it is http://localhost:3205/Service1.svc

Step 4) Add Service Reference to SilverlightApplication Project, it will create a proxy class.

Step5)  in the XAML Add button and Label to grid layout
<Grid x:Name="LayoutRoot" Height="378">
        <TextBlock Text="File Uploading in Silverlight using WCF Service" FontSize="16" Foreground="Red" Margin="10,10,-10,332"
                 
>
           
        </TextBlock>       
        <Button Content="Upload File(s)" HorizontalAlignment="Left" VerticalAlignment="Top" Width="159" x:Name="fileuploadone" Margin="192,106,0,0" Click="fileuploadone_Click" Height="27"/>
        <sdk:Label Content="no uploaded files" x:Name="lblfilestats" HorizontalAlignment="Left" Height="123" VerticalAlignment="Top" Width="454" Margin="58,176,0,0"/>

     

    </Grid>

Button handler invokes dialog box to select  a file(s).
Label will display Filename uploaded to server using WCF Service.

Step 6) Invoke upload WCF service client in Button Handler.

        private void fileuploadone_Click(object sender, RoutedEventArgs e)
        {
 try
            {
                OpenFileDialog od = new OpenFileDialog();
                od.Multiselect = true;
                bool? b = od.ShowDialog().GetValueOrDefault(true);
                if (b.HasValue)
                {
                    if (b.Value == true)
                    {
                        ServiceReference1.Service1Client client = new ServiceReference1.Service1Client();
                        foreach (FileInfo fi in od.Files)
                        {
                          
                            lblfilestats.Content = fi.Name + fi.Length + fi.Extension;
                            FileStream fs = fi.OpenRead();
                            byte[] bytes = new byte[fs.Length];
                          
                            client.uploadsAsync(bytes,fi.Name);
                            client.uploadsCompleted += client_uploadsCompleted;
                        }
                    }
                    else MessageBox.Show("showdialog returns false");
                    // od.Files
                }
                else MessageBox.Show("showdialog returns no value");
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }          

        }

        void client_uploadsCompleted(object sender, ServiceReference1.uploadsCompletedEventArgs e)
        {
            if (e.Error != null)
            {
                MessageBox.Show(e.Error.Message);
                return;
            }
            if (e.Result)lblupload.Content="Success";
            else  lblupload.Content="Failed";

          
        }

Step 7) Check Uploads Folder for uploaded files
