Upload File In Silverlight

Silverlight doesn't have upload control, here we are uploading a file using OpenFileDialog from silverlight client to server location using wcf.

Step 1.

In Silverlight Web application -> Add -> Add New Item -> Silverlight-enabled wcf -> Add.

Step 2.
In WCF,
[OperationContract]

public void SaveFile(UploadFile uploadfile)

{
            FileStream filestream = new FileStream("E:\\Uploaded\\" + uploadfile.FileName, FileMode.Create);
            filestream.Write(uploadfile.File, 0, uploadfile.File.Length);
            filestream.Close();
            filestream.Dispose();
  }

        

[DataContract]

public class UploadFile

{
            [DataMember]
            public string FileName;
            [DataMember]
            public byte[] File;

}

Step 3.

Add service reference -

Step 4.

//MainPage.xaml

Step 5.

//MainPage.xaml.cs

public OpenFileDialog fileDialog = null;

        

public MainPage()

{
         InitializeComponent();
 }

 private void btnUploadFile_Click(object sender, RoutedEventArgs e)
 {
         ServiceReference1.Service1Client service = new ServiceReference1.Service1Client();
         fileDialog = new OpenFileDialog();
         fileDialog.Filter = "All Files|*.*";
         bool? result = fileDialog.ShowDialog();
         if (result != null && result == true)
         {

                Stream strm = fileDialog.File.OpenRead();
                byte[] Buffer = new byte[strm.Length]; strm.Read(Buffer, 0, (int)strm.Length);
                strm.Dispose();
                strm.Close();

                //Accessing DataContract...

                ServiceReference1.Service1UploadFile file = new ServiceReference1.Service1UploadFile();
                file.FileName = fileDialog.File.Name;
                file.File = Buffer;
                service.SaveFileAsync(file);
                service.SaveFileCompleted += new EventHandler                 <System.ComponentModel.AsyncCompletedEventArgs>(service_SaveFileCompleted);
        }
        else
        {
                txtMsg.Text = "Plz Select File !!! ";
         }

    }

  public void service_SaveFileCompleted(object sender,    System.ComponentModel.AsyncCompletedEventArgs e)
 {
        if (e.Error == null)
             txtMsg.Text = fileDialog.File.Name + "Successfully Saved";
  }
