Question

I keep getting this error "LetterDemo.cs(21,14): error CS1519: Unexpected symbol `string' in class, struct, or interface member declaration"

Can someone please help me.

Here is my code:

using static System.Console;

class LetterDemo

{

   static void Main()

   {

     Letter letter1 = new Letter();

     CertifiedLetter letter2 = new CertifiedLetter();

     letter1.Name = "Electric Company";

     letter1.Date = "02/14/18";

     letter2.Name = "Howe and Morris, LLC";

     letter2.Date = "04/01/2019";

     letter2.TrackingNumber = "i2YD45";

     WriteLine(letter1.ToString());

     WriteLine(letter2.ToString() +

      " Tracking number: " + letter2.TrackingNumber);

   }

}

class Letter

{

  pubic string Name {get; set;}

  pubic string Date {get; set;}

  public new string ToString()

  {

    return(GetType() + " To: " + Name + " Date mailed : " + Date);

  }

}

class CertifiedLetter : Letter

{

  public string TrackingNumber {get; set;}

}

C# Program:

using static System.Console;
class LetterDemo{
    static void Main() {
        Letter letter1 = new Letter();
        CertifiedLetter letter2 = new CertifiedLetter();
        letter1.Name = "Electric Company";
        letter1.Date = "02/14/18";
        letter2.Name = "Howe and Morris, LLC";
        letter2.Date = "04/01/2019";
        letter2.TrackingNumber = "i2YD45";
        WriteLine(letter1.ToString());
        WriteLine(letter2.ToString() + " Tracking number: " + letter2.TrackingNumber);
  }
}

class Letter
{
    public string Name {get; set;}
    public string Date {get; set;}

    public new string ToString()
    {
        return(GetType() + " To: " + Name + " Date mailed : " + Date);
    }
}

class CertifiedLetter : Letter
{
  public string TrackingNumber {get; set;}
}

Output:

NOTE: You did very small mistake

pubic string Name {get; set;} ==> pubic is nothing in programming language, should be public

pubic string Date {get; set;} ==> same as above

Thumbs Up Please !!!
