另一个"读取XML数据时已超出最大字符串内容长度配额(8192)." WCF和Silverlight 4的问题

Question

我可以轻松检索大量数据,但将其发送回服务会显示此错误.我已经尝试将该元素添加到web.config和servicereferences.clientconfig中,并且在两者中都无法识别.有一次,我得到了一条关于将readerQuotas添加到bindingElementExtensions的消息,但是我找不到任何有关如何执行此操作的有用信息.我发现帖子说我必须修改devenv.exe.config等等,但是这样做了.我一直试图解决这两天,所以任何帮助将不胜感激.

编辑:这是web.config的绑定部分:

<bindings>
  <customBinding>
    <binding name="QaRiM.Web.Service1.customBinding0">
      <binaryMessageEncoding />
      <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" />
    </binding>
  </customBinding>
</bindings>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"
  multipleSiteBindingsEnabled="true" />
<services>
  <service name="QaRiM.Web.Service1">
    <endpoint address="" binding="customBinding" bindingConfiguration="QaRiM.Web.Service1.customBinding0"
      contract="QaRiM.Web.Service1" />
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
</services>

和servicereferences.clientconfig:

<configuration>
    <system.serviceModel>
        <bindings>
            <customBinding>
                <binding name="CustomBinding_Service1">
                    <binaryMessageEncoding />
                    <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" />
                </binding>
            </customBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost:36533/Service1.svc" binding="customBinding"
                bindingConfiguration="CustomBinding_Service1" contract="ServiceReference1.Service1"
                name="CustomBinding_Service1" />
        </client>
    </system.serviceModel>
</configuration>

两者都是由VS生成的.

Answer 1

您只是缺少最大字符串内容长度的配置.

将此添加到绑定属性(客户端和服务器)

<readerQuotas maxStringContentLength="2147483647" />

抱歉,我没有意识到这个子元素位于使用自定义绑定时使用的编码下,它似乎binaryMessageEncoding在您的示例中.如果没有,请尝试使用该设置进行其他编码.

<bindings>
    <customBinding>
        <binding name="QaRiM.Web.Service1.customBinding0">                  
            <binaryMessageEncoding>
                <readerQuotas maxStringContentLength="2147483647"/>
            </binaryMessageEncoding>
        </binding>
    </customBinding>
</bindings>
