文件从ClientBase <t> </t>上载到WCF服务

我目前正致力于将文件上传和下载到WCF服务的解决方案。客户端是继承自ClientBase的类。我已经阅读了有关StackOverflow和其他地方的流媒体和链接的MSDN article,但我似乎无法弄清楚为什么我仍然收到有关消息大小太小的消息。到目前为止,我已经使用小文件测试了解决方案并且它可以工作

该服务托管在IIS 7.5

这是来自客户端应用程序的App.config

<system.web>
    <httpRuntime maxRequestLength="67108864" />
</system.web>
<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding messageEncoding="Mtom" transferMode="Streamed" name="LargeFileStreamingHttpBinding"
                     maxBufferSize="65536"
                     maxReceivedMessageSize="2147483647">
                <readerQuotas maxDepth="32" maxArrayLength="200000000" maxStringContentLength="200000000"/>
            </binding>

        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://localhost/UpdateService.svc"
                        binding="basicHttpBinding"
                        contract="IUpdateService"
                        name="updateServiceEndpoint"/>

    </client>
</system.serviceModel>

以下是服务器中的相关部分

<system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>

    <services>
        <service name="UpdateService" behaviorConfiguration="UpdateServiceBehavior">
                <endpoint binding="basicHttpBinding" bindingName="LargeFileStreamingWebHttpBinding" contract="IUpdateService"></endpoint>
                <endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
        </service>
    </services>

    <behaviors>
        <serviceBehaviors>
                <behavior name="UpdateServiceBehavior" >
                        <serviceMetadata httpGetEnabled="true" />
                        <serviceDebug includeExceptionDetailInFaults="true" />
                </behavior>
        </serviceBehaviors>
    </behaviors>

    <bindings>
        <basicHttpBinding>
                <binding messageEncoding="Mtom" transferMode="Streamed" name="LargeFileStreamingWebHttpBinding" 
                                 maxBufferSize="65536" 
                                 maxReceivedMessageSize="2147483647"
                                 />
        </basicHttpBinding>
    </bindings>
</system.serviceModel>

此外,我在服务器和客户端配置中添加了以下内容:

<system.web>
    <httpRuntime maxRequestLength="2147483647" />
</system.web>

这就是我实例化客户端的方式

public class UpdateClient : ClientBase<IUpdateService>, IUpdateService
{
    public UpdateClient() : base("updateServiceEndpoint") {}
}

那么我有什么想法可能会出错吗?任何帮助表示赞赏。

-Thanks!
