How to make an Object persistance:
You can make an object serializable. It will save the object and/or its values in a binary or Xml files based on the format you specified.
Tips: Use binary formatter when you are that you serialized object's consumer will also be a .net framework program.
Otherwise its safe to use XML formatter and this way you can more easily read and write files. However be concern about the security threat as xml file is readable.

Here is a simple program.

Code:

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using System.Xml.Serialization;

namespace XMLSerializeDeserialize
{
    class Program
    {
        static void Main(string[] args)
        {
            /// Create XML Serialization
            FileStream fs = new FileStream("xml.XML", FileMode.Create);
            XmlSerializer xmls = new XmlSerializer(typeof(DateTime));
            xmls.Serialize(fs, DateTime.Now);
            fs.Close();
            /// End OF XML Creation
            /// start DESERIALIZATION

            FileStream fr = new FileStream("xml.XML",FileMode.Open);
            DateTime Pt = (DateTime) xmls.Deserialize(fr);
            fr.Close();
            Console.WriteLine(Pt.ToString());
            Console.Read();
        }
    }
}

The Generated XML:

Code:

<?xml version="1.0"?>
<dateTime>
   2009-05-18T21:51:42.46875+06:00
</dateTime>

Here i am serializing a date-time object. You can easily see that, the XML file is created under the current project directory [ specifically in the BIN folder under DEBUG].

Though you can also do some more complex serialization and Deserialization. You can also deserialize complex object property in runtime.

Hope we will talk about this in next post.

Happy CODING.
BE IN GRID.
