Using Read method


using System.IO;
using System;// Program to read every line in the file using Read method of StreamReader

class ReadFile
{
    static void Main()
    {
        string fileloc="D://MyFile.txt";    // File location
        
        // creates file
        FileStream fs = new FileStream(fileloc, FileMode.Create);
        fs.Close();
        Console.WriteLine("File created successfully");

        // writes to file
        StreamWriter sw = new StreamWriter(fileloc);
        sw.WriteLine("first line");
        sw.WriteLine("second line");
        sw.Flush();
        sw.Close();
        Console.WriteLine("Written to file successfully");
        
        // Lets read the file now
        Console.WriteLine("Content of file :");        
       
        StreamReader sr = new StreamReader(fileloc);
        while (sr.Peek() >= 0)
        {
            Console.Write((char)sr.Read()); // Reads as character by character
        }
        Console.ReadLine();
    }
}

Output:
File created successfully
Written to file successfully
Content of file:
