Question

Visual Studio C#

1. Correct all syntax errors within the given program.

2. Correct all logic errors within the given program – there should be 4 events. Check the working application for validation.

3. In Form1.cs, there is a foreach loop that is repeated. Create a method for this loop so that the foreach loop is only written once, and there are two calls to your new method.

4. Add a new type of event (such as a play or a festival – requires the creation of a new subclass of Ticket). Add this event to the form including a picture of the event.

Program:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace TicketPurchasing
{
public abstract class Ticket
{
//Private data
private double cost;
private string nameOfEvent;
private string location;
private string fileName;

//Constructor
public Ticket()
{

}

//Constructor
public Ticket(double c, string n, string l, string f)
{
cost = c;
nameOfEvent = n;
location = l;
fileName = f;
}

//Setters
public void setCost(double c)
{
cost = c;
}

public void setName(string n)
{
nameOfEvent = n;
}

public void setLocation(string l)
{
location = l;
}

public void setFileName(string f)
{
fileName = f;
}

//Getters
public double getCost()
{
return cost;
}

public string getName()
{
return nameOfEvent;
}

public string getLocation()
{
return location;
}

public string getFileName()
{
return fileName;
}

public virtual string getDetails()
{
return "Name of event: " + nameOfEvent +
" Location: " + location +
" Ticket cost: " + cost.ToString("c");
}
}
}
