    <p>I'm receiving data in dictionary form and would like to deserialize it into a dynamic object. The twist is the dictionary keys express a hierarchical object. A second twist is some of the keys express an array and/or dictionary property.</p> <p>For example:</p> <pre><code>===========Key================ ======Value======== Person.First | John Person.Last | Doe Person.Phone[Work] | 999-555-1234 Person.Phone[Home] | 999-555-1235 Person.Addresses[Home].Street | 101 My Street Person.Addresses[Home].City | AnyTown Person.Spouse.First | Jane Person.Spouse.Last | Doe Person.Insurance[0].Name | Medicare Person.Insurance[0].GroupNum | 1234567 </code></pre> <p><strong>Edit</strong>: Added array examples</p> <p>I'm trying to find a simple method to create an object that can then be used in a runtime expressions evaluator.</p> <p>Here's my first attempt that works for the simple properties, but doesn't attempt to handle the arrays</p> <pre><code>public static class DynamicBuilder { public static object Build(IDictionary&lt;string, object&gt; dict) { ExpandoObject root = new ExpandoObject(); foreach (var item in dict) { var objDict = (IDictionary&lt;string, object&gt;)root; var parts = item.Key.Split('.'); for (int i = 0; i &lt; parts.Length ; i++) { string propName = parts[i]; if (i &lt; parts.Length - 1) { if (!objDict.ContainsKey(propName)) { dynamic temp = new ExpandoObject(); objDict.Add(propName, temp); objDict = (IDictionary&lt;string, object&gt;)temp; } else { objDict = (IDictionary&lt;string, object&gt;)objDict[propName]; } } else { if (objDict.ContainsKey(propName)) objDict[propName] = item.Value; else objDict.Add(propName, item.Value); } } } return root; } } </code></pre> <p>Any ideas on better way to approach this?</p> <p>Thanks,</p>

    1. COAre there actually array properties in the data? In your example you've only shown dictionary properties and I just want to make sure you're not confusing array definition with dictionary access.

    3. COLooks like a reasonable approach. Maybe one thing: you should split that method into smaller ones to improve readability.

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.
