1. Create class “FileDirc” have some method

• void AddDir():create folders as structure

• void AddFile(): add 03 file to CSharp folders as

• void WriteLog():  create and write xml file as

<?xml version="1.0" encoding="utf-8" ?>
<log>
<folder>
<size>123468 Bytes</size>
<content>3 Files, 5 Folders</content>
</folder>
</log>

• void ViewCont ():

• Using built in attribute make “ViewCont” only run on Debug mode

The anwser:
- Ran class
[sourcecode language="CSharp"]
using System;
using System.Collections.Generic;
using System.Text;
using System.Xml;
namespace XML
{
class Program
{
static void Main(string[] args)
{
FinalTest01 obj = new FinalTest01();
obj.AddDir();
obj.AddFile();
obj.WriteLog();
obj.ViewCont();
Console.ReadLine();
}
}
}
[/sourcecode]
