以编程方式修改端点 ReaderQuotas [英] Modify endpoint ReaderQuotas programmatically

问题描述

我有一个服务的动态客户端.如何更改其端点绑定的 ReaderQuotas 属性?

I have a dynamic client to a service. How can i change the ReaderQuotas property of it's endpoint binding?

我这样试过，但它不起作用......

I tried like this but it doesn't work ...

 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;
   }

即使这样做之后，ReaderQuotas 值仍然是默认值.

Even after doing this the ReaderQuotas values remain the default ones.

我也这样试过，还是不行:

I also tried like this and still doesn't work:

     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，所以我可以向服务发送超过 8kb 的数据.

I need this so I can send more than 8kb to the service.

推荐答案

在创建绑定后在 BindingElement 上设置配额对该绑定没有影响.

Setting quotas on a BindingElement after the binding is created has no effect on that binding.

编辑(因为你不知道使用的是什么绑定):

Edit (since you don't know what binding is used):

您可以使用反射来设置属性.请注意，在设置 Binding 之前，您应该确保它确实具有该属性.并非所有绑定都具有此属性.如果您尝试在不支持它的绑定上设置它，该示例将引发异常.

You can use reflection to set the property. Note you should make sure the Binding actually has the property before setting it. Not all bindings have this property. If you try to set it on a binding that doesn't support it, the example will throw an exception.

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);
