WCF帖子文件限制

Question

我在SharePoint中托管的WCF服务在前一段时间内运行良好，但它现在不起作用，我不明白它为什么会发生。我尝试将文件发布到服务并获得错误400（badrequest）如果文件少16Kb没有错误。我改变了我的配置文件

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_IDocumentSetService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
          <security mode="TransportCredentialOnly">
            <transport clientCredentialType="Ntlm" proxyCredentialType="None" realm="" />
            <message clientCredentialType="UserName" algorithmSuite="Default" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://localhost/_vti_bin/documentset.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IDocumentSetService" contract="Sitronics.AFK.BoD.SharePoint.Services.Services.IDocumentSetService" name="BasicHttpBinding_IDocumentSetService" />
    </client>
  </system.serviceModel>

我需要在服务器端修改maxArrayLength，我该怎么办？服务主机按以下方式配置

public class DocumentSetServiceFactory : MultipleBaseAddressBasicHttpBindingServiceHostFactory
    {
        protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
        {
            var sh = base.CreateServiceHost(serviceType, baseAddresses);

            sh.Opening += sh_Opening;

            return sh;
        }

        public override ServiceHostBase CreateServiceHost(string constructorString, Uri[] baseAddresses)
        {
            var sh = base.CreateServiceHost(constructorString, baseAddresses);

            sh.Opening += sh_Opening;

            return sh;
        }

        void sh_Opening(object sender, EventArgs e)
        {
            var sh = (ServiceHostBase)sender;

            LoggingService.LogDebug("DocumentServiceHost:Opening");

            if (sh.Description != null)
            {

                LoggingService.LogDebug("DocumentServiceHost:Description is not null");

                foreach (var endPoint in sh.Description.Endpoints)
                {

                    LoggingService.LogDebug(string.Format("DocumentServiceHost:FOR ENDPOINT {0}", endPoint.Address));

                    var bec = endPoint.Binding.CreateBindingElements();
                    var transport = bec.Find<TransportBindingElement>();

                    if (transport != null)
                    {
                        LoggingService.LogDebug(string.Format("DocumentServiceHost:TRANSPORT {0}",transport.Scheme));


                        transport.MaxReceivedMessageSize = 5242880;
                        transport.MaxBufferPoolSize = 5242880;
                    }
                }
            }
        }        
    }
