c# super class code example

Example 1: c# superclass constructor

// Create Constructor in superclass
public Vehicle( double speed )
    {
      Speed = speed;
      LicensePlate = Tools.GenerateLicensePlate();
    }

//Original Constructor
class Sedan
  {
    public Sedan(double speed)
    {
      Speed = speed;
      LicensePlate = Tools.GenerateLicensePlate();
      Wheels = 4;
    }

// Remove 'Speed' and 'LicensePlate' from Sedan Constructor
// Add 'class Sedan : Vehicle '
// Add 'public Sedan(double speed) : base(speed)'
  
//New Constructor
class Sedan : Vehicle
  {
    public Sedan(double speed) : base(speed)
    {
      Wheels = 4;
    }
  }

Example 2: list of 2 different inherent classes c#

// a Pseudo-example using interfaces. <--- Worked great for me!

public interface IPrinter
{
   void Send();
   string Name { get; }
}

public class PrinterType1 : IPrinter
{
  public void Send() { /* send logic here */ }
  public string Name { get { return "PrinterType1"; } }
}

public class PrinterType2 : IPrinter
{
  public void Send() { /* send logic here */ }
  public string Name { get { return "Printertype2"; } }

  public string IP { get { return "10.1.1.1"; } }
}


// ...
// then to use it
var printers = new List<IPrinter>();

printers.Add(new PrinterType1());
printers.Add(new PrinterType2());

foreach(var p in printers)
{
  p.Send();

  var p2 = p as PrinterType2;

  if(p2 != null) // it's a PrinterType2... cast succeeded
    Console.WriteLine(p2.IP);
}

Example 3: c# implement a superclass in subclass

class Sedan : Vehicle
{
}

// class Sedan will now inherit Vehicles' members

class Sedan : Vehicle, IAutomobile
{
}

// Sedan will now inherit Vehicles' members and promise to
//				  implement the functions of interface IAutomibile
