WCF Service Communication Exception Due to Parameter Size

问题

I've got a WCF Web MEthod that takes in an XElement object as a parameter. For one of my XML files (sized at 600KB or so) this works just fine, however, for this bigger XML file (about 5MB) I get a CommunicationException right away.

I've already increased the message sizes for my binding. Below is the ServiceModel section of my web.config:

<system.serviceModel>
<behaviors>
  <serviceBehaviors>
    <behavior name="BIMIntegrationWS.metadataBehavior">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
    <behavior name="">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
  </serviceBehaviors>
</behaviors>        

<bindings>
  <customBinding>        
    <binding name="BIMIntegrationWS.IntegrationService.customBinding0"
      closeTimeout="00:01:00" openTimeout="00:01:00"
      receiveTimeout="00:10:00" sendTimeout="00:10:00">
      <binaryMessageEncoding>
        <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
                        maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
      </binaryMessageEncoding>
      <httpTransport  maxBufferPoolSize="2147483647"   maxBufferSize="2147483647"
                      maxReceivedMessageSize="2147483647" />
    </binding>
  </customBinding>
</bindings>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
<services>      
  <service name="BIMIntegrationWS.BIMIntegrationWS" behaviorConfiguration="BIMIntegrationWS.metadataBehavior">
    <endpoint address="" binding="customBinding" bindingConfiguration="BIMIntegrationWS.IntegrationService.customBinding0"
     contract="BIMIntegrationWS.IBIMIntegrationService" />
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
</services>
</system.serviceModel>

On the client, my ClientConfig looks like this:

<system.serviceModel>      
      <bindings>
            <customBinding>                
                  <binding name="CustomBinding_IBIMIntegrationService">
                    <binaryMessageEncoding />
                    <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" />                                       
                  </binding>
            </customBinding>
      </bindings>        
    <client>          
        <endpoint address="http://localhost:1895/IntegrationService.svc"
            binding="customBinding" bindingConfiguration="CustomBinding_IBIMIntegrationService"
            contract="BIMIntegrationService.IBIMIntegrationService" name="customBindingEndpoint" />
    </client>
</system.serviceModel>

Thanks in advance!

try to add following snippet into your web.config for the service application:

  <system.web>
    <httpRuntime maxRequestLength="16384" /> <!-- 16MB -->
  </system.web>

When you host the service in web server you also have to tweak allowed request size for the web server.

Maybe your XElement has too many nodes/child elements, and you need to set the maxItemsInObjectGraph attribute under dataContractSerializer to something larger?

回答3:

You probably need to change the values of the attributes of the <readerQuotas /> sub element of <binaryMessageEncoding />.

Update: Can you try to increase the maxAllowedContentLength as described here: http://social.msdn.microsoft.com/Forums/en/wcf/thread/e6e21132-ad3f-4135-8ab9-77923b099907

Do you know how to turn off VS host and to just deploy to IIS and give it a ping. Normal IIS 7 on your dev box will do just fine. You can still attach debugger etc, just won't have instantaneous F5 gratification but since your ocode is not dying on startup you don't need to see if from the fist line anyway :-)

If you would need to attach very early you could could make a mimimal method that doesn't tounch anything at all and just returns int constnat - just to bring up app pool so you can attach.
