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。我该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?

我尝试过这种方法，但是它不起作用...

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，ReaderQuotas值仍为默认值。

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

我也这样尝试，但仍然无法正常工作：

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，所以我可以发送超过8kb的服务空间。

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无效。

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

编辑（因为您不知道使用什么绑定）：

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，在设置绑定之前，应确保绑定实际上具有该属性。并非所有绑定都具有此属性。如果您尝试将其设置为不支持的绑定，则该示例将引发异常。

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);

希望这对您有所帮助。
