    <p>I'm trying to work out how to extract a List of objects from a JSON request in a WEBAPI call. Within this list of objects is a Dictionary object, a List object and a List> object.</p> <p>My request from my MVC controller, looks a bit like this:</p> <pre><code>//Gets a list of various objects List&lt;object&gt; values = new List&lt;object&gt;(); values.add(GetItem1()); //Returns a Dictionary&lt;string, string&gt; object values.add(GetItem2()); //Returns a List&lt;string&gt; object values.add(GetItem3()); //List&lt;KeyValuePair&lt;string, string&gt;&gt; var content = new StringContent(JsonConvert.SerializeObject(values), Encoding.UTF8, "application/json"); HttpResponseMessage postResult = client.PostAsync(baseURL, content).Result; </code></pre> <p>In the WEBAPI object, I have this function that is receiving the call from the MVC controller. This is where I have my trouble, I can't get the data out of the List. The first item in the list, happens to be a Dictionary.</p> <pre><code>[HttpPost] public void LogError(List&lt;object&gt; myObjectList) { Dictionary&lt;string, string&gt; items = (Dictionary&lt;string, string&gt;)myObjectList[0]; List&lt;string&gt; moreItems = (List&lt;string&gt;)myObjectList[1]; List&lt;KeyValuePair&lt;string, string&gt;&gt; evenMoreItems = (List&lt;KeyValuePair&lt;string, string&gt;&gt;)myObjectList[2]; } </code></pre> <p>If I try to start using the object, I get the error:</p> <pre><code>Cannot cast 'myObjectList[0]' (which has an actual type of 'Newtonsoft.Json.Linq.JObject') to 'System.Collections.Generic.Dictionary&lt;string,string&gt;' </code></pre> <p>Unfortunately, I'm at a complete loss about what to do next. I can't seem to find a way to deserialize the List into these individual object types. </p>

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.
