What I have tried:

public class BaseEmployee
  {
      public int Id;
      public string Name;
  }

  public class Employee : BaseEmployee
  {
      public string Address;


      public  static  Object Adding()
      {
          Employee employeeDetail = new Employee();
          Console.Write("Employee Id:");
          employeeDetail.Id = int.Parse(Console.ReadLine());

          Console.Write("Employee Name:");
          employeeDetail.Name = Console.ReadLine();
          Console.Write("Employee Address:");
          employeeDetail.Address = Console.ReadLine();
          return employeeDetail;


      }
static void Main(string[] args)
      {
          string pathString = @"c:\SpecifiedFiles\MyNewFile.txt";

          Boolean p = true;

          while (p)
          {
              Console.WriteLine("Employee Record Managemnet system");
              Console.WriteLine("1)Add");
              Console.WriteLine("2)Edit");
              Console.WriteLine("3)Dispaly");
              Console.WriteLine("4)Delete");
              Console.WriteLine("Select operation");


              int option = int.Parse(Console.ReadLine());
              switch(option)
              {
                  case 1:
                      TextWriter tw = new StreamWriter(@"c:\SpecifiedFiles\MyNewFile.txt");
                      tw.Write(Adding());

                      tw.Close();
                       break;

                  case 2:
                      TextReader tr = new StreamReader(@"c:\SpecifiedFiles\MyNewFile.txt");

                      Console.WriteLine(tr.ReadLine());
                      Console.WriteLine(tr.ReadToEnd());
                      tr.Close();
                     break;
               }
          }
       }
      }
  }

                int option = int.Parse(Console.ReadLine());
                switch (option)
                {
                    case 1:
                        TextWriter tw = new StreamWriter(@"D:\temp\MyNewFile.txt");
                        var outObj = Adding();
                        string tempStr = "Id: " + outObj.Id + Environment.NewLine + "Emp Name: " + outObj.Name + Environment.NewLine + "Emp Address: " + outObj.Address;
                        tw.Write(tempStr);
                        tw.Close();
                        break;

                    case 2:
