Sending byte array to WCF Service

Question

Hello I tried all solutions from stackoverflow.com but it didn't work for me.

Here is my code

WCF Service:

public void SendImage(byte[] img, string filename)
{
    MemoryStream memoryStream = new MemoryStream(img);
    FileStream stream = new FileStream(AppDomain.CurrentDomain.BaseDirectory + filename, FileMode.Create);
    memoryStream.CopyTo(stream);
    stream.Close();
}

Interface:

[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Xml, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "sendImage")]
void SendImage(byte[] img, string filename);

Here is my Web.Config:

My question is why I get:

System.ServiceModel.ProtocolException: The remote server returned an unexpected response: (413) Request Entity Too Large. ---> System.Net.WebException: The remote server returned an error: (413) Request Entity Too Large. at System.Net.HttpWebRequest.GetResponse() at System.ServiceModel.Channels.HttpChannelFactory`1.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout) --- End of inner exception stack trace ---

When I run this code:

private void buttonSendToServer_Click(object sender, RoutedEventArgs e)
{
    imageCtrl.Source = null;
    ServiceReference1.RestServiceImplClient service = new ServiceReference1.RestServiceImplClient();
    foreach (MyBitmap bit in listBitmap)
    {
        string s;
        try
        {
            service.SendImage(bit.GetBytes(), bit.FileName);
        }
        catch (ProtocolException ex)
        {
            s = ex.ToString();
        }
    }
    service.Close();
}

Solution

On the WCF end (i.e., separate from IIS), you're not using the binding you defined in the service config file (Binding1):

<endpoint address="" binding="basicHttpBinding"
          contract="WcfService1.IRestServiceImpl" 
          behaviorConfiguration="web">

You specify the type of binding to use, but since you didn't specify the configuration to use, you will get the default settings for basicHttpBinding. To specify the binding configuration, use the bindingConfiguration attribute, like this:

<endpoint address="" binding="basicHttpBinding" 
          bindingConfiguration="Binding1"
          contract="WcfService1.IRestServiceImpl"
          behaviorConfiguration="web">

There could be other configurations to, but this is the most common reason from a WCF perspective.
