FILE INCLUDED WITH ASSIGNMENT IS NAMED: InputRead2.txt           Insiside this text document is this: eafcdfghijlk         Program we are using: C# with Visual Studios

Assignment:

Using the techniques you learned in the previous activity, develop code that will take input, line-by-line, from a file and write output to a file. The output file should have the characters alphabetized, line-by-line.

You will accomplish this by creating a method, “alphabetize”, which has the following method header:

//public static string alphabetize(string letters)

//Takes a string of letters passed to it, converts to an array of characters (use: ToCharArray()), uses Array.Sort to alphabetize, converts

//back to string (new string(char[])and returns the alphabetized version to calling program

Explanation / Answer

//below codes reads the file by line by line and converts the string to char_array and sortes the string and writes the string into the file.

using System;

using System.IO;

namespace FileIOApplication
{
class Program
{
static void Main(string[] args)
{
int counter = 0;
       string line;
       try{
       System.IO.StreamReader file = new System.IO.StreamReader("I: est.txt");//reading file string line by line.
       while((line = file.ReadLine()) != null){
           char[] c=line.ToCharArray();
           Array.Sort(c); //sorting into the alphabetize order
           string sortedLine=String.Empty;
           foreach (char ch in c)
           sortedLine+=ch.ToString() ;
           System.IO.File.WriteAllText ("c: est.txt", sortedLine); //it will write the sorted string in the same file.
       }
       file.Close();
       Console.ReadLine();
   }
   catch (Exception e){Console.Write("Error while reading file");}
}
}
}
