 Author : Praksh Pradeep Gopu

Now am going to explain reading all file name in the directory and save the file name in a xml format .To read the file names in a directory is a file system task so include using System.IO; name space to your console application.

Get files from directory

 

To get all file names in the directory use the Method Directory.GetFiles returns string array with files names.

 Syntax :

String[] files = Directory.GetFiles(“<filepath>”);

To get the files with specified extension the use the second argument of Directory.GetFiles method. Syntax is as follows :

string[] filePaths = Directory.GetFiles(@"c:\MyDir\", "*.bmp");

It will return all file names in the directory C:\Mydir with file extension .bmp.

Get files from directory (including all subdirectories)

To get files from directory with all its subdirectories pass the third argument of Directory.GetFiles method.

Syntax :

string[] filePaths = Directory.GetFiles(@"c:\MyDir\", "*.bmp",

                                        SearchOption.AllDirectories);

The following program will explain you to get all files which extension .pdf in D:\BlogerDir and saving as the xml file.

D:\ BlogerDir has the following directory structure :

 

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.IO;

using System.Xml;

namespace FileConsile

{

   public class CreteXML

    {

        static void Main(string[] args)

        {

            //Getting all the files in the D:\BlogerDir with extension .pdf

            String[] files = Directory.GetFiles(@"D:\BlogerDir", "*.pdf", SearchOption.AllDirectories);

            //Declaring a xmldocument

            XmlDocument doc = new XmlDocument();

            //creating a Files node in the xmldocument

            XmlNode FilesNode = doc.CreateElement("Files");

            doc.AppendChild(FilesNode);

        

            for (int i = 0; i < files.Length; i++)

            {

                FileInfo info = new FileInfo(files[i]);

                string name = files[i].ToString();

                XmlNode InfoNode = doc.CreateElement("File");

                XmlNode nameNode = doc.CreateElement("Name");

                nameNode.InnerText = name;

                InfoNode.AppendChild(nameNode);

                XmlNode sizeNode = doc.CreateElement("Size");

                sizeNode.InnerText = info.Length.ToString();

                InfoNode.AppendChild(sizeNode);

              

                FilesNode.AppendChild(InfoNode);

            }

         

            //saving the xml document in the path D:\MyXml.xml

            doc.Save(@"D:\MyXml.xml");

         

          Console.WriteLine(doc.InnerXml.ToString());

          Console.ReadLine();

        }

    }

}

Out put :
