题
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。
解决方案
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。
其他提示
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; 强>
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);
}
