Question

Using C#

Create a “Main” method that will take user input one line at a time until they enter the phrase “done”. Store each line entered into an ArrayList, so that one element of the ArrayList is one line of user input. You do NOT need to write your own ArrayList class, please use the standard library implementation of an ArrayList.

After the user finishes typing in input, ask the user for a location and file name. Save the contents of the ArrayList, with line separations between each entered line, into a new file with the entered location and name.

Print a message saying that the new file was successfully created and written to. If an exception occurs, then please print a message saying why the creation failed and ask the user for a new location and file name. Continue to ask for a new location and file name until the user enters a viable location and name and no exception occurs.

Finally, print out the contents of the new file.

using System;

using System.Collections;

public class WriteToFile {

  public static void Main(String[] args){

    ArrayList lines=new ArrayList();

    Console.WriteLine("Enter lines (done to quit):");

    String s=Console.ReadLine();

    while(!s.Equals("done")) {

      lines.Add(s);

      s=Console.ReadLine();

    }

    Console.WriteLine("Enter file name: ");

    String name=Console.ReadLine();

    using (System.IO.StreamWriter file =

new System.IO.StreamWriter(@name))

{

foreach (string line in lines)

{

file.WriteLine(line);

}

}

    

    

    Console.WriteLine("new file was successfully created and written to");

  }

}
