Отправка байтового массива в службу WCF

Question

Здравствуйте, я пробовал все решения из stackoverflow.com, но это не сработало для меня.

Вот мой код

службы WCF:

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(); 
} 

Интерфейс:

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

Вот мой Web.Config:

    <system.serviceModel> 
     <client> 
      <endpoint address="http://localhost:55008/RestServiceImpl.svc"

       bindingConfiguration="BasicHttpBinding_IRestServiceImpl"

    <system.web>

    </system.web> 
</configuration> 

Мой вопрос, почему я получаю:

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 ---

Когда я запускаю этот код:

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(); 
}

В конце WCF (т. е. отдельно от IIS), вы не используете привязку, определенную в конфигурационном файле службы (Binding1):

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

Вы указываете тип связывания для использования, но так как вы не указали конфигурацию для использования, вы получите настройки по умолчанию для basicHttpBinding. Чтобы задать конфигурацию связывания, используйте атрибут bindingConfiguration, как это:

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

Там могут быть и другие конфигурации, но это является наиболее распространенной причиной с точки зренияWCF.
