    <p>I have a WCF service that can accept a <code>byte[]</code>. I'm creating a client using <code>HttpClient</code> and am receiving the following error. I've read online that you have to set the <code>readerQuotas</code> on both the server and the client, but how do I set these settings on the <code>HttpClient</code>?</p> <h3>Error:</h3> <blockquote> <p>There was an error deserializing the object of type RTM.API.Resources.UGCRequest. The maximum array length quota (16384) or the maximum items in object graph quota has been exceeded while reading XML data. These quotas may be increased by changing the MaxArrayLength property on XmlDictionaryReaderQuotas or the MaxItemsInObjectGraph setting.</p> </blockquote> <h3>Server Config:</h3> <pre class="lang-xml prettyprint-override"><code> &lt;standardEndpoints&gt; &lt;webHttpEndpoint&gt; &lt;standardEndpoint name="" helpEnabled="true" automaticFormatSelectionEnabled="true" maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647" maxBufferSize="2147483647"/&gt; &lt;standardEndpoint name="DirectoryEndpoint"/&gt; &lt;/webHttpEndpoint&gt; &lt;/standardEndpoints&gt; &lt;services&gt; &lt;service name="API.Service.UGCService" behaviorConfiguration="DataServiceBehavior"&gt; &lt;endpoint contract="API.Service.UGCService" kind="webHttpEndpoint" endpointConfiguration="" binding="webHttpBinding" bindingConfiguration="BigHttpBinding"/&gt; &lt;/service&gt; &lt;/services&gt; &lt;behaviors&gt; &lt;serviceBehaviors&gt; &lt;behavior name="DataServiceBehavior"&gt; &lt;serviceDebug includeExceptionDetailInFaults="true"/&gt; &lt;dataContractSerializer maxItemsInObjectGraph="2147483644"/&gt; &lt;/behavior&gt; &lt;/serviceBehaviors&gt; &lt;/behaviors&gt; &lt;bindings&gt; &lt;webHttpBinding&gt; &lt;binding name="BigHttpBinding" transferMode="Buffered" maxReceivedMessageSize="2147483647" &gt; &lt;readerQuotas maxArrayLength="2147483647" maxDepth="2147483647" maxStringContentLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/&gt; &lt;/binding&gt; &lt;/webHttpBinding&gt; &lt;/bindings&gt; </code></pre> <h3>Client code:</h3> <pre class="lang-cs prettyprint-override"><code>using (HttpClient client = new HttpClient(apiPath)) { using (HttpRequestMessage request = new HttpRequestMessage(method, finalUrl)) { request.Headers.Accept.AddString("application/json"); request.Headers.Add("Authorization", sb.ToString()); if (method == "POST" || method == "PUT") { if (requestBody.Count() == 0) request.Headers.ContentLength = 0; else { request.Content = HttpContent.Create(APM6.Utils.Serialize(requestBody), "application/json"); } } using (HttpResponseMessage response = client.Send(request)) { return response.Content.ReadAsString(); } } } </code></pre>

    1. COJust as an off-topic, I've been struggling with WCF for 6 months now and I would **not** recommend using it to exposing a JSON interface (its lots of intricacies doesn't pay the effort). If you want to stick with Microsoft technologies and can evaluate an alternative, take a look at WebAPI.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
