File Writing (C#.net)

Writing in File:   

The namespace for writing a data in file is System.IO which contains built-in classes and functions to handle files.

Code

Way One:

using System.IO;

public class WritingFile

{

    public static void Main(string[] args) 

       

      {

        

            TextWriter tw = File.CreateText(@"d:\Osama_Stuff\Billy.txt");

           

          try

            {

                String writeText = Console.ReadLine();

                tw.WriteLine(writeText);

                tw.Flush(); // To send data from stream to file

              

            }

            catch (Exception e)

            {

                Console.WriteLine(e.ToString());

            }

            finally

            {

                tw.Close();

            }

      

      }

}

Way Second:

try

  {

   FileStream fs = new FileStream("abc1.txt", FileMode.Create, FileAccess.Write);

   StreamWriter sw = new StreamWriter(fs);

   sw.WriteLine("I am osama mursleen");

   sw.Flush(); 

  }

  catch (Exception ex)

  

  {

     Console.WriteLine(ex.Message);

  

  }

Appending Data In File:

try

  {

   FileStream fs = new FileStream("abc1.txt", FileMode.Append, FileAccess.Write);

   StreamWriter sw = new StreamWriter(fs);

   sw.WriteLine("I am osama mursleen");

   sw.Flush(); 

 }

  catch (Exception ex)

  

  {

     Console.WriteLine(ex.Message);

  

  }
