class filexercise3
{
    public static void Main()
    {
        string fileName = @"mytest.txt"; 

        try
        {
            // Delete the file if it exists.
            if (File.Exists(fileName))
            {
                File.Delete(fileName);
            }
			Console.Write("\n\n Create a file with text and read the file  :\n");
			Console.Write("-------------------------------------------------\n");            
            // Create the file.
            using (StreamWriter fileStr = File.CreateText(fileName)) 
            {
                fileStr.WriteLine(" Hello and Welcome");
                fileStr.WriteLine(" It is the first content");

            using (StreamReader sr = File.OpenText(fileName))
            {
                string s = "";
				Console.WriteLine(" Here is the content of the file mytest.txt : ");
                while ((s = sr.ReadLine()) != null)
                {
                    Console.WriteLine(s);
                }
                Console.WriteLine("");
            }
        }
        catch (Exception MyExcep)
        {
            Console.WriteLine(MyExcep.ToString());
        }
    }
}
