Can't seem to add XmlIgnore override on inherited property

11/22/2005 9:09:19 AM    Can't seem to add XmlIgnore override on inherited property
By the way, I also posted this on DotNet Framework General. 
 
I'm trying to serialize, via the XmlSerializer, an object which is derived 
 
from System.Windows.Forms.Control.  It throws an exception complaining about 
 
not being able to serialize the Site property.  I expected problems and my 
 
plan was to work through them one at a time supplying an XmlIgnore attribute 
 
for each of the properties it had problems with.  However, for some reason 
 
this doesn't seem to work.  The code is below.  Does anyone know why it's 
 
still throwing the exception complaining about the Site property after 
 
specifying the XmlIgnore attribute for that property? 
 
using System; 
 
using System.Windows.Forms; 
 
using System.Xml.Serialization; 
 
using System.IO; 
 
using System.Drawing; 
 
public class MyControl : Control 
 
{ 
 
public MyControl() 
 
{ 
 
} 
 
} 
 
public class Application 
 
{ 
 
public static void Main() 
 
{ 
 
MyControl    control = new MyControl(); 
 
XmlSerializer   serializer; 
 
XmlAttributes   attributes; 
 
XmlAttributeOverrides overrides; 
 
overrides = new XmlAttributeOverrides(); 
 
attributes = new XmlAttributes(); 
 
attributes.XmlIgnore = true; 
 
overrides.Add(typeof(MyControl), "Site", attributes); 
 
control.Font = new Font("Arial", 12); 
 
serializer = new XmlSerializer(typeof(MyControl), overrides); 
 
serializer.Serialize(Console.OpenStandardOutput(), control); 
 
} 
 
}

Thanks,

I don't know if you'll ever succeed doing what you want, serializing the 
 
state of a control, but anyway I can answer your question on the xml 
 
attribute overrides. 
 
you want: 
 
overrides.Add(typeof(System.ComponentModel.Component), "Site",  attributes); 
 
The overrides.Add()  wants a name of a type, and also a member name within  that type, to override. 
 
Your type MyControl has no member by the name Site. 
 
The Site member is on the type System.ComponentModel.Component, which is the  base type of Control.
