Question

我从一些存根调用WCF服务。问题是，我不能在客户端拥有app.config。所以我在我的代码中设置值。

服务web.config显示如下值：

  <system.serviceModel>
    <diagnostics>
      <messageLogging logMalformedMessages="true" logMessagesAtTransportLevel="true" />
    </diagnostics>
    <behaviors>
        <serviceBehaviors>
            <behavior>
                <serviceMetadata httpGetEnabled="true"/>
                <serviceDebug includeExceptionDetailInFaults="true"/>
            </behavior>
        </serviceBehaviors>
    </behaviors>
    <bindings>
       <basicHttpBinding>
         <binding name="BasicHttpBinding_IStatementsManagerService" openTimeout="00:10:00" 
                closeTimeout="00:10:00" sendTimeout="00:10:00" receiveTimeout="00:10:00"
                allowCookies="false" bypassProxyOnLocal="true" 
                hostNameComparisonMode="StrongWildcard"
                maxBufferSize="567890" maxBufferPoolSize="524288" maxReceivedMessageSize="567890"
                messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
                useDefaultWebProxy="true">
            <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" 
                          maxArrayLength="2147483647" maxBytesPerRead="2147483647" 
                          maxNameTableCharCount="2147483647" />
           <!--<security mode="None">
             <transport clientCredentialType="None" proxyCredentialType="None"
                 realm="" />
             <message clientCredentialType="UserName" algorithmSuite="Default" />
           </security>-->
         </binding>
       </basicHttpBinding>
    </bindings>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true"/>
    <services>
      <service name="PathFINDER.Services.IStatementsManagerService">
        <endpoint address="" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IStatementsManagerService"
                contract="PopulateReqProServiceERReqs.IStatementsManagerService"
                name="BasicHttpBinding_IStatementsManagerService" />
            <endpoint kind="mexEndpoint" address="mex" />
      </service>
    </services>
    </system.serviceModel>

客户端的代码是这样的：

            BasicHttpBinding binding = new BasicHttpBinding();
            //System.ServiceModel.Channels.Binding binding = new BasicHttpBinding();
            TimeSpan t = new TimeSpan(0, 2, 0);
            binding.Name = "BasicHttpBinding_IStatementsManagerService";
            binding.CloseTimeout = new TimeSpan(00, 01, 00);
            binding.OpenTimeout = new TimeSpan(00, 01, 00);
            binding.ReceiveTimeout = new TimeSpan(00, 10, 00);
            binding.SendTimeout = new TimeSpan(00, 10, 00);

            binding.AllowCookies = false;
            binding.BypassProxyOnLocal = false;
            binding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
            binding.MaxBufferSize = 567890;
            binding.MaxBufferPoolSize = 524288;
            binding.MaxReceivedMessageSize = 567890;
            binding.MessageEncoding = WSMessageEncoding.Text;
            //binding.TextEncoding= "utf-8";
            binding.TransferMode = TransferMode.Buffered;
            binding.UseDefaultWebProxy = true;

            binding.ReaderQuotas.MaxDepth=2147483647;
            binding.ReaderQuotas.MaxStringContentLength=2147483647;
            binding.ReaderQuotas.MaxArrayLength=2147483647;
            binding.ReaderQuotas.MaxBytesPerRead=2147483647;
            binding.ReaderQuotas.MaxNameTableCharCount=2147483647; 

            string ServiceUrl = "http://localhost:56620/StatementsManagerService.svc";
            System.ServiceModel.EndpointAddress remoteAddress = new System.ServiceModel.EndpointAddress(ServiceUrl);
            PopulateReqProService.StatementsManagerServiceClient Smsc = new PopulateReqProService.StatementsManagerServiceClient(binding, remoteAddress);
            blnReturn = Smsc.MyMethod(MyParam);

但问题是，当我在参数中调用包含大量数据的服务时，它会失败，并且在svclog文件中我可以清楚地看到异常：

传入邮件的最大邮件大小限额（65536）被超过了。要增加配额，请使用MaxReceivedMessageSize 适当的绑定元素上的属性。

有人可以帮忙吗？我没有得到任何线索。

Answer 1

您只需要增加MaxReceivedMessageSize属性，因为您调用的方法返回的数据长度大于567890.只需在服务器和客户端上试验这些值。

Answer 2

您还需要设置binding的{{1}}部分中指定的值（在客户端<ReaderQuotas>代码中）！

web.config

然后它应该工作：

Answer 3

在行为方面，您需要设置此项，请尝试以下代码：

maxItemsInObjectGraph="2147483646"

我知道这是一个非常古老的问题，但仍然存在。

为什么我的WCF客户端的绑定设置不起作用？
