    <p>I'm attempting to create a recursive routine that will retrieve PropertyInfos for all members under a specified object (in .NET 3.5). Everything for immediate members is working, but it needs to parse nested classes as well (and their nested classes, etc).</p> <p>I do not understand how to handle the section that parses nested classes. How would you write this part of the code?</p> <pre><code>public class ObjectWalkerEntity { public object Value { get; set; } public PropertyInfo PropertyInfo { get; set; } } public static class ObjectWalker { // This will be the returned object static List&lt;ObjectWalkerEntity&gt; objectList = new List&lt;ObjectWalkerEntity&gt;(); public static List&lt;ObjectWalkerEntity&gt; Walk(object o) { objectList.Clear(); processObject(o); return objectList; } private static void processObject(object o) { if (o == null) { return; } Type t = o.GetType(); foreach (PropertyInfo pi in t.GetProperties()) { if (isGeneric(pi.PropertyType)) { // Add generic object ObjectWalkerEntity obj = new ObjectWalkerEntity(); obj.PropertyInfo = pi; obj.Value = pi.GetValue(o, null); objectList.Add(obj); } else { ////// TODO: Find a way to parse the members of the subclass... // Parse each member of the non-generic object foreach (Object item in pi.PropertyType) { processObject(item); } } } return; } private static bool isGeneric(Type type) { return Extensions.IsSubclassOfRawGeneric(type, typeof(bool)) || Extensions.IsSubclassOfRawGeneric(type, typeof(string)) || Extensions.IsSubclassOfRawGeneric(type, typeof(int)) || Extensions.IsSubclassOfRawGeneric(type, typeof(UInt16)) || Extensions.IsSubclassOfRawGeneric(type, typeof(UInt32)) || Extensions.IsSubclassOfRawGeneric(type, typeof(UInt64)) || Extensions.IsSubclassOfRawGeneric(type, typeof(DateTime)); } </code></pre> <p><strong>Edit:</strong> I've used some of Harlam's suggestions, and came up with a working solution. This handles both nested classes and lists.</p> <p>I've replaced my previous loop through the propertyinfo with the following</p> <pre><code>foreach (PropertyInfo pi in t.GetProperties()) { if (isGeneric(pi.PropertyType)) { // Add generic object ObjectWalkerEntity obj = new ObjectWalkerEntity(); obj.PropertyInfo = pi; obj.Value = pi.GetValue(o, null); objectList.Add(obj); } else if (isList(pi.PropertyType)) { // Parse the list var list = (IList)pi.GetValue(o, null); foreach (object item in list) { processObject(item); } } else { // Parse each member of the non-generic object object value = pi.GetValue(o, null); processObject(value); } } </code></pre> <p>I've also added a new check to see if something is a list.</p> <pre><code>private static bool isList(Type type) { return IsSubclassOfRawGeneric(type, typeof(List&lt;&gt;)); } </code></pre> <p>Thanks for the help!</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.
