Question

编码员，这个问题让我抓狂！我在过去的两天里一直在进行广泛的研究，我不知道发生了什么。

问题：正如标题所说，我有一个由Silverlight应用程序使用的WCF服务。问题是每当我尝试使用其中一个WCF操作时，我都会收到此错误：

读取XML数据时已超出最大字符串内容长度配额（8192）。

我知道我应该将web.config中MaxStringContentLength的值更改为适合我的消息大小的值，但在我看来，更新MaxStringContentLength的值不会反映在系统中。我试图更新服务参考，重建整个解决方案没有运气，仍然得到相同的错误。知道我应该做什么吗？

解决方案信息：

带有WCF文件夹的Asp.net项目。
消耗的Silverlight项目 WCF。

我没有看到web.config文件中任何地方定义的服务 - 你只需要一个服务客户端定义。我很惊讶这项服务甚至是这样的。可能会复制并粘贴错误？

这是我的web.config，用于类似的场景（你缺少标记的部分）：

<system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
    <behaviors>
        <serviceBehaviors>
            <behavior name="MyDefaultBehavior">
                <serviceMetadata httpGetEnabled="true" />
            </behavior>
        </serviceBehaviors>
    </behaviors>
    <bindings>
        <basicHttpBinding>
            <binding name="MyDefaultBinding" allowCookies="true" maxReceivedMessageSize="20000000" maxBufferSize="20000000">
                <readerQuotas maxDepth="500" maxArrayLength="20000000" maxStringContentLength="20000000"/>
            </binding>
        </basicHttpBinding>
    </bindings>
    <services> <!-- This appears missing from your web.config -->
        <service behaviorConfiguration="MyDefaultBehavior" name="MyProject.MyService">
            <endpoint address="" binding="basicHttpBinding" contract="MyProject.IMyService" bindingConfiguration="MyDefaultBinding" />
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        </service>
    </services>
</system.serviceModel>

WCF MaxStringContentLength永远不会更新！
