Create a project and use Enterprise Library configuration to open web. config
Create configsection.
Rename to edit,
Create a new one at the edit node.
XML file storage provider

Then save

Using System;
Using System. text;
Using System. xml. serialization;


Namespace Intlib
{
/**/ /// <Summary>
///Persen's summary.
/// </Summary>
Public   Class Persen
{
Private   String Name;
Private   Int Age;
Private   String Country;

Public Persen ()
{
//
//Todo: add the constructor logic here
//
}

Public   String Name
{
Get {ReturnName ;}
Set {Name=Value ;}
}

Public   Int Age
{
Get {ReturnAge ;}
Set {Age=Value ;}
}
Public   String Country
{
Get {ReturnCountry ;}
Set {Country=Value ;}

}



}
}

 
One is write and the other is read,

Private   Void Button#click ( Object Sender, system. eventargs E)
{
Persen PS = New Persen ();
PS. Name = This . Textbox1. text;
PS. Age = Int . Parse ( This . Textbox2.text );
PS. Country = This . Textbox3.text;
Configurationmanager. writeconfiguration ( " Edit " , PS );

}

Private   Void Button2_click ( Object Sender, system. eventargs E)
{
Persen PS = Configurationmanager. getconfiguration ( " Edit " ) As Persen;
This . Textbox1. Text = PS. Name;
This . Textbox2.text = PS. Age. tostring ();
This . Textbox3.text = PS. Country;

}

The Enterprise Library will automatically serialize and deserialize objects...
Reading and writing data from config .....
