reflection PropertyInfo. How to select properties of the derived class?

[Steve Richter]

when enumerating thru the properties of a type, how do I select only
the properties of the derived class? In the example below, the
AddrBookPrompt class is derived from the Form class. When I enumerate
the properties I get all the properties of the base class + the
properties of my derived class.

thanks,
AddrBookPrompt abPmt = new AddrBookPrompt( );
abPmt.FirstName = "Steve";
abPmt.LastName = "Richter";

System.Type type = abPmt.GetType() ;
PropertyInfo[] piArray = type.GetPropert ies();
foreach (PropertyInfo pi in piArray)
{
ListViewItem item = new ListViewItem(pi .Name);
item.Tag = pi;
item.SubItems.A dd(pi.PropertyT ype.Name);
item.SubItems.A dd(pi.Module.Na me );
mLvProperties.I tems.Add(item);
}

Use the overload which takes a BindingFlags, and make sure that you
include DeclaredOnly (as well as whatever other flags you want (eg
Instance, Public).

where do I specify DeclaredOnly and BindingFlags?

I think I have the answer. I compare the "DeclaringType. Name" of the
property with the Type.Name of the type I am listing the properties
of:

AddrBookPrompt abPmt = new AddrBookPrompt( );

System.Type type = abPmt.GetType() ;
PropertyInfo[] piArray = type.GetPropert ies();
foreach (PropertyInfo pi in piArray)
{
if (pi.DeclaringTy pe.Name == type.Name)
{
ListViewItem item = new ListViewItem(pi .Name);
item.Tag = pi;
item.SubItems.A dd(pi.PropertyT ype.Name);
item.SubItems.A dd(pi.Module.Na me);
item.SubItems.A dd(pi.Declaring Type.Name);
mLvProperties.I tems.Add(item);
}
}

thanks,

DeclaredOnly is a member of the BindingFlags enum, which you can pass
to GetProperties.

I think I have the answer. I compare the "DeclaringType. Name" of the
property with the Type.Name of the type I am listing the properties
of:

You could do that, but it would be better to get GetProperties to
filter for you.
