修改端点ReaderQuotas编程

Question

我有一个动态客户端的服务。我怎样才能改变它的ReaderQuotas属性的端点绑定？

我想这样的，但它不工作...

 DynamicProxyFactory factory = new DynamicProxyFactory(m_serviceWsdlUri);

 foreach (ServiceEndpoint endpoint in factory.Endpoints)
 {
     Binding binding =  endpoint.Binding;

     binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxArrayLength = 2147483647
     binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxBytesPerRead =2147483647;
     binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxDepth = 2147483647;
     binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxNameTableCharCount = 2147483647;
     binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxStringContentLength = 2147483647;
   }

即使这样做的ReaderQuotas后值保持默认的。

我也试过这样，仍然不工作：

     DynamicProxyFactory factory = new DynamicProxyFactory(m_serviceWsdlUri);

     foreach (ServiceEndpoint endpoint in factory.Endpoints)
     {
         System.ServiceModel.Channels.BindingElementCollection bec = endpoint.Binding.CreateBindingElements();

         System.ServiceModel.Channels.TransportBindingElement tbe = bec.Find<System.ServiceModel.Channels.TransportBindingElement>();

         tbe.MaxReceivedMessageSize = 2147483647;
         tbe.MaxBufferPoolSize = 2147483647;
         TextMessageEncodingBindingElement textBE = bec.Find<TextMessageEncodingBindingElement>();

         if (textBE != null)
         {

             textBE.ReaderQuotas.MaxStringContentLength = 2147483647;
             textBE.ReaderQuotas.MaxArrayLength = 2147483647;
             textBE.ReaderQuotas.MaxBytesPerRead = 2147483647;
             textBE.ReaderQuotas.MaxDepth = 2147483647;
             textBE.ReaderQuotas.MaxNameTableCharCount = 2147483647;

         }
   }

我需要这个，所以我可以超过8KB到服务发送更多。

设置在BindingElement配额被创建的绑定之后对没有影响结合。

编辑（因为你不知道是做什么用绑定）：

可以使用反射来设置属性。请注意，您应该确保绑定实际上已经将它设置前的属性。并非所有绑定都具有此属性。如果你试图把它放在一个绑定，不支持，该示例将抛出一个异常。

Binding binding = endpoint.Binding;

XmlDictionaryReaderQuotas myReaderQuotas = new XmlDictionaryReaderQuotas();
myReaderQuotas.MaxStringContentLength = _sanebutusablelimit_;
myReaderQuotas.MaxArrayLength = _sanebutusablelimit_;
myReaderQuotas.MaxBytesPerRead = _sanebutusablelimit_;
myReaderQuotas.MaxDepth = _sanebutusablelimit_;
myReaderQuotas.MaxNameTableCharCount = _sanebutusablelimit_;

binding.GetType().GetProperty("ReaderQuotas").SetValue(binding, myReaderQuotas, null);

希望这有助于你一点。

你为什么要解决，在一个如此复杂的方式，只是直接改变ReaderQuotas：

即：

的WSHttpBinding WebBinding =新的WSHttpBinding（）;

<强> WebBinding.ReaderQuotas.MaxArrayLength = int.MaxValue; WebBinding.ReaderQuotas.MaxStringContentLength = int.MaxValue; WebBinding.ReaderQuotas.MaxBytesPerRead = int.MaxValue;

此将工作而没有奇怪的反射样品。

干杯

另外要注意的是，结合的下列属性还需要完整的解决方案进行更新：

binding2.MaxBufferSize = 2147483647;
binding2.MaxReceivedMessageSize = 2147483647;

有关他人这里的好处是，编程设置客户端，并与2个属性以上沿着服务器上的ReaderQuotas样品：

客户端的代码：

        WebHttpBinding binding2 = new WebHttpBinding();
        XmlDictionaryReaderQuotas myReaderQuotas = new XmlDictionaryReaderQuotas();
        myReaderQuotas.MaxStringContentLength = 2147483647;
        myReaderQuotas.MaxArrayLength = 2147483647;
        myReaderQuotas.MaxBytesPerRead = 2147483647;
        myReaderQuotas.MaxDepth = 2147483647;
        myReaderQuotas.MaxNameTableCharCount = 2147483647;

        binding2.GetType().GetProperty("ReaderQuotas").SetValue(binding2, myReaderQuotas, null);
        binding2.MaxBufferSize = 2147483647;
        binding2.MaxReceivedMessageSize = 2147483647;
        ServiceEndpoint ep = new ServiceEndpoint(ContractDescription.GetContract(typeof(IMyService)),
            binding2, new EndpointAddress("http://localhost:9000/MyService"));

        WebChannelFactory<IMyService> cf2 = new WebChannelFactory<IMyService>(ep);

        IMyService serv = cf2.CreateChannel();
        serv.PrintNameDesc("Ram", new string('a', 100*1024*1024));

服务器代码：

        WebHttpBinding binding2 = new WebHttpBinding();
        XmlDictionaryReaderQuotas myReaderQuotas = new XmlDictionaryReaderQuotas();
        myReaderQuotas.MaxStringContentLength = 2147483647;
        myReaderQuotas.MaxArrayLength = 2147483647;
        myReaderQuotas.MaxBytesPerRead = 2147483647;
        myReaderQuotas.MaxDepth = 2147483647;
        myReaderQuotas.MaxNameTableCharCount = 2147483647;

        binding2.GetType().GetProperty("ReaderQuotas").SetValue(binding2, myReaderQuotas, null);
        binding2.MaxBufferSize = 2147483647;
        binding2.MaxReceivedMessageSize = 2147483647;

        WebServiceHost host2 = new WebServiceHost(typeof(MyService));
        host2.AddServiceEndpoint(typeof(IMyService), binding2, new Uri("http://localhost:9000/MyService"));

        host2.Open();

如果合同是：

[ServiceContract]
public interface IMyService
{
    [WebInvoke(Method = "PUT", 
        UriTemplate = "My/{name}/", 
        BodyStyle = WebMessageBodyStyle.Bare, 
        ResponseFormat = WebMessageFormat.Xml, 
        RequestFormat = WebMessageFormat.Xml)]
    [OperationContract]
    void PrintNameDesc(string name, string desc);
}
