Hi
I have a Generics List in a PropertyGrid
I am able to Serialize it to XML but when I try to deserialize back to the
class of the PropertyGrid
The Constructor doesn't seem to fire to reload the saved settings
Can anyone see something that I have missed ?
Class of values
----------------
[XmlRoot("ValueS tring")]
public class ValueString
{
private string upper = "uppervalue ";
private string lower = "lowervalue ";
public ValueString()
{
}
public ValueString(str ing sUpper, string sLower)
{
upper = sUpper
lower = sLower;
}
[XmlElement("Upp er")]
public string Upper
{
get { return upper; }
set { upper = value; }
}
[XmlElement("Low er")]
public string Lower
{
get { return lower; }
set { lower = value; }
}
}
PropertGrid Class
----------------
private List<ValueStrin gmyValues = new List<ValueStrin g>();
myValues.Add("u pper1","lower1" );
myValues.Add("u pper2","lower2" );
[Category("Misc" )]
[Browsable(false )]
[XmlArrayItem("V alArray")]
public List<ValueStrin gValuesStr
{
get
{
return myValues
}
set
{
myValues = value;
}
}
xml serialized from Class
-----
<ValuesStr>
<ValArray>
<Upper>upper1 </Upper>
<Lower>lower1 </Lower>
</ValArray>
<ValArray>
<Upper>upper2 </Upper>
<Lower>lower2 </Lower>
</ValArray>
</ValuesStr>

AFAIK, the way that the deserialize operation of XML Arrays works is
that it constructs an array object (not a List<>) from scratch and
assigns it - meanwhile deserialization requires only an IEnumerable.
Your List<works fine for deserializing since it's an IEnumerable, bu
not the other way because it's not an Array.
I might be wrong about this - but that's just he behaviour I'm
observing. Perhaps providing a public Array-based property that is
converted to-and-from your hidden List property (converting from lists
to arrays and vice versa is pretty simple) - then just serialize your
Array.

Ick, a bit of a brain fart there: I said "Deserializ e" when I meant
"Serialize" a bunch of times. Serialize from IEnumerable, deserialize
from Array.
from http://msdn2.microsoft.com/en-us/lib....xmlarray.aspx
"""Gets or sets an object that specifies how the XmlSerializer
serializes a public field or read/write property that returns an
*array*. """ (emph. mine).

Simple. I have instance of my object, that contains data in interfaces.

Even if I don't make any child classes it throws "Object reference not
