Answer 1

Do you have to read in character by character? The following code will do the whole thing as a block and return you a list containing all your lines.

var contents = File.ReadAllLines (@"C:\Users\user1\Documents\data.txt")
                   .Select (l => l.Replace ("\"", ";\""));

Answer 2

Try ch = (char)reader.Peek();

This will read tell you the next character without reading it. You can then use this to check if it is a " or not an insert : accordingly

if (Convert.ToInt32((char)read.Peek()) == 34) Console.Write(@";")

Answer 3

Swap the order of the operations:

    if (Convert.ToInt32(ch) == 34)
    {
        Console.Write(@";");
    }
    Console.Write(ch);

e.g. don't write the original character until AFTER you've decided to output a semicolon or not.

using System;
using System.IO;
using System.Text;

namespace getto
{
  class Program
  {
     static void Main(string[] args)
     {
         var path = @"C:\Users\VASANTH14122018\Desktop\file.v";

         string content = File.ReadAllText(path, Encoding.UTF8);
        Console.WriteLine(content);
        //string helloWorld = "Hello, world!";
        foreach(char c in content)
            {
                Console.WriteLine(c);
            }
        Console.Write("Press any key to continue . . . ");
        Console.ReadKey(true);
    }
  }
}
