I use a Silverlight enabled Web Service to save Silverlight captured snapshots to MSSQL server database. when I run the project silverlight app is working fine but the images doesn''t save in the database. I tried a lot of different methods but I couldn''t find any solution. Can anyone please help me to solve this problem? thanks.. this is my code

CaptureSource source; WriteableBitmap bitmap; ImageService.ImageServiceClient client = new ImageService.ImageServiceClient(); //MainPage.xaml.cs private void CaptureImageCompleted(object sender, CaptureImageCompletedEventArgs e) { try { client.OpenAsync(); bitmap = new WriteableBitmap(e.Result); byte[] buffer = bitmap.ToByteArray(); client.SaveImageAsync(buffer, txtname.Text); txtname.Text = "Done"; } catch (Exception e1) { txtname.Text = "Error"; } }

SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnStr"].ConnectionString); //ImageService.svc.cs [OperationContract] public void SaveImage(byte[] buffer, String Name) { ImageConverter ic = new ImageConverter(); Image img = (Image)ic.ConvertFrom(buffer); try { conn.Open(); SqlCommand insertCommand = new SqlCommand("Insert into [pics] (label, pic) Values (@Label, @Pic)", conn); insertCommand.Parameters.Add("Pic", SqlDbType.Image, 0).Value = ConvertImageToByteArray(img, ImageFormat.Jpeg); insertCommand.Parameters.Add("Label", SqlDbType.VarChar, 0).Value = Name; int queryResult = insertCommand.ExecuteNonQuery(); } catch (Exception e1) { } } //Convert Image to byte[] private byte[] ConvertImageToByteArray(Image imageToConvert, ImageFormat formatOfImage) { byte[] Ret; try { using (MemoryStream ms = new MemoryStream()) { imageToConvert.Save(ms, formatOfImage); Ret = ms.ToArray(); } } catch (Exception) { throw; } return Ret; }
