There was an error generating the XML document.

Hi All,

I have a DLL contains two classes, first one which is to be serialized
and other one is a UserControl class have code to serialize as below:-

class XYZ: System.Windows. Forms.UserContr ol
{

public XYZ()
{
string _preferencesFil e = "c:\test_xml.xm l";

XMLTest.PrefDat a _preferences = new XMLTest.PrefDat a();

XmlTextWriter writer = new XmlTextWriter(_ preferencesFile ,
System.Text.Enc oding.UTF8);
XmlSerializer serializer = null ;
writer.Formatti ng = Formatting.Inde nted;
serializer = new XmlSerializer(t ypeof(XMLTest.P refData));
//serializer.Seri alize(writer,pr eferences);
serializer.Seri alize(writer,(X MLTest.PrefData )_preferences);
writer.Flush();
writer.Close();
}

.......

Now If I create the object of XYZ like below

System.Windows. Forms.UserContr ol xyz = new XYZ();

the code written in the constructor works fine.

But I load this usercontrol thru reflection then it throw the error
"There was an error generating the XML document. " and inner exception
as "Specified cast is not valid";

Assembly asmAssemblyCont ainingForm = Assembly.LoadFr om("XMLTest.dll ");
Type typeToLoad = asmAssemblyCont ainingForm.GetT ype("XMLTest.XY Z");
System.Windows. Forms.UserContr ol allocationInsta nce =
(System.Windows .Forms.UserCont rol)Activator.C reateInstance(t ypeToLoad);

Please let me know if there are thoughts to solve this problem.

Thanks,
Utkarsh
