This is a followup to my previous question, which got solved (thank you for that) but now I am stuck at another error.
I'm trying to save an image in my database (called 'Afbeelding'), for that I made a table which excists of:
id: int
souce: varbinary(max)
I then created a wcf service to save an 'Afbeelding' to the database.
private static DataClassesDataContext dc = new DataClassesDataContext();
[OperationContract]
public void setAfbeelding(Afbeelding a)
{
//Afbeelding a = new Afbeelding();
//a.id = 1;
//a.source = new Binary(bytes);
dc.Afbeeldings.InsertOnSubmit(a);
dc.SubmitChanges();
}
I then put a reference to the service in my project and when I press the button I try to save it to the datbase.
private void btnUpload_Click(object sender, RoutedEventArgs e)
{
Afbeelding a = new Afbeelding();
OpenFileDialog openFileDialog = new OpenFileDialog();
openFileDialog.Filter = "JPEG files|*.jpg";
if (openFileDialog.ShowDialog() == true)
{
//string imagePath = openFileDialog.File.Name;
//FileStream fileStream = new FileStream(imagePath, FileMode.Open, FileAccess.Read);
//byte[] buffer = new byte[fileStream.Length];
//fileStream.Read(buffer, 0, (int)fileStream.Length);
//fileStream.Close();
Stream stream = (Stream)openFileDialog.File.OpenRead();
Byte[] bytes = new Byte[stream.Length];
stream.Read(bytes, 0, (int)stream.Length);
string fileName = openFileDialog.File.Name;
a.id = 1;
a.source = new Binary { Bytes = bytes };
}
EditAfbeeldingServiceClient client = new EditAfbeeldingServiceClient();
client.setAfbeeldingCompleted +=new EventHandler<System.ComponentModel.AsyncCompletedEventArgs>(client_setAfbeeldingCompleted);
client.setAfbeeldingAsync(a);
}
void client_setAfbeeldingCompleted(object sender, System.ComponentModel.AsyncCompletedEventArgs e)
{
if (e.Error != null)
txtEmail.Text = e.Error.ToString();
else
MessageBox.Show("WIN");
}
However, when I do this, I get the following error:
System.ServiceModel.FaultException: The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter :a.
The InnerException message was 'There was an error deserializing the object of type OndernemersAward.Web.Afbeelding.
The maximum array length quota (16384) has been exceeded while reading XML data. This quota may be increased by changing the MaxArrayLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader.'.
Please see InnerException for more details.

I'm not sure what's causing this but I think it has something to do with the way I write the image to the database? (The array length is too big big, I don't really know how to change it)
Thank you for your help,
Thomas
