如果您在使用WCF测试客户端时仍然得到这个错误消息，这是因为客户端有一个单独的MaxBufferSize设置。

要纠正这个问题:

右键单击树底部的Config File节点 选择用SvcConfigEditor编辑

将出现一个可编辑的设置列表，包括MaxBufferSize。

注意:自动生成的代理客户端也默认设置MaxBufferSize为65536。

如果你正在动态创建你的WCF绑定，下面是使用的代码:

BasicHttpBinding httpBinding = new BasicHttpBinding();
httpBinding.MaxReceivedMessageSize = Int32.MaxValue;
httpBinding.MaxBufferSize = Int32.MaxValue;
// Commented next statement since it is not required
// httpBinding.MaxBufferPoolSize = Int32.MaxValue;

我解决了我的问题在必应地图WPF在我的项目使用CalculateRoute()。 在我的案例中的解决方案是设置maxReceivedMessageSize和maxReceivedMessageSize属性“httpTransport”为“customBinding”部分。

我设置了应用程序。配置文件。配置myApp.config)

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_IGeocodeService" />
            <binding name="BasicHttpBinding_IRouteService" />
        </basicHttpBinding>
        <customBinding>
            <binding name="CustomBinding_IGeocodeService">
                <binaryMessageEncoding />
              <httpTransport manualAddressing="false" maxBufferPoolSize="524288"
                                maxReceivedMessageSize="2147483647" allowCookies="false" authenticationScheme="Anonymous"
                                bypassProxyOnLocal="false" decompressionEnabled="true" hostNameComparisonMode="StrongWildcard"
                                keepAliveEnabled="true" maxBufferSize="2147483647" proxyAuthenticationScheme="Anonymous"
                                realm="" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false"
                                useDefaultWebProxy="true" />
            </binding>
            <binding name="CustomBinding_IRouteService">
                <binaryMessageEncoding />
              <httpTransport manualAddressing="false" maxBufferPoolSize="524288"
                                maxReceivedMessageSize="2147483647" allowCookies="false" authenticationScheme="Anonymous"
                                bypassProxyOnLocal="false" decompressionEnabled="true" hostNameComparisonMode="StrongWildcard"
                                keepAliveEnabled="true" maxBufferSize="2147483647" proxyAuthenticationScheme="Anonymous"
                                realm="" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false"
                                useDefaultWebProxy="true" />
            </binding>
        </customBinding>
    </bindings>
    <client>
        <endpoint address="http://dev.virtualearth.net/webservices/v1/geocodeservice/GeocodeService.svc"
            binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IGeocodeService"
            contract="BingServices.IGeocodeService" name="BasicHttpBinding_IGeocodeService" />
        <endpoint address="http://dev.virtualearth.net/webservices/v1/geocodeservice/GeocodeService.svc/binaryHttp"
            binding="customBinding" bindingConfiguration="CustomBinding_IGeocodeService"
            contract="BingServices.IGeocodeService" name="CustomBinding_IGeocodeService" />
        <endpoint address="http://dev.virtualearth.net/webservices/v1/routeservice/routeservice.svc"
            binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IRouteService"
            contract="BingServices.IRouteService" name="BasicHttpBinding_IRouteService" />
        <endpoint address="http://dev.virtualearth.net/webservices/v1/routeservice/routeservice.svc/binaryHttp"
            binding="customBinding" bindingConfiguration="CustomBinding_IRouteService"
            contract="BingServices.IRouteService" name="CustomBinding_IRouteService" />
    </client>
</system.serviceModel>

对我来说，我所要做的就是在客户端app.config中添加maxReceivedMessageSize="2147483647"。服务器没有受到影响。

对于HTTP:

<bindings>
  <basicHttpBinding>
    <binding name="basicHttp" allowCookies="true"
             maxReceivedMessageSize="20000000" 
             maxBufferSize="20000000"
             maxBufferPoolSize="20000000">
        <readerQuotas maxDepth="200" 
             maxArrayLength="200000000"
             maxBytesPerRead="4096"
             maxStringContentLength="200000000"
             maxNameTableCharCount="16384"/>
    </binding>
  </basicHttpBinding>
</bindings>

TCP:

<bindings>
  <netTcpBinding>
    <binding name="tcpBinding"
             maxReceivedMessageSize="20000000"
             maxBufferSize="20000000"
             maxBufferPoolSize="20000000">
      <readerQuotas maxDepth="200"
           maxArrayLength="200000000"
           maxStringContentLength="200000000"
           maxBytesPerRead="4096"
           maxNameTableCharCount="16384"/>
    </binding>
  </netTcpBinding>
</bindings>

重要的是:

如果你试图传递一个复杂的对象，这个对象有很多连接的对象(例如:一个树数据结构，一个有很多对象的列表……)，无论你如何增加配额，通信都会失败。 在这种情况下，你必须增加包含对象的计数:

<behaviors>
  <serviceBehaviors>
    <behavior name="NewBehavior">
      ...
      <dataContractSerializer maxItemsInObjectGraph="2147483646"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

从我的经验来看，另一件需要考虑的重要事情是…

我强烈建议不要最大化maxBufferPoolSize，因为在应用程序域(即应用程序池)回收之前，池中的缓冲区永远不会释放。

一段时间的高流量可能会导致大量内存被使用，并且永远不会释放。
