c# inheritance super

// 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; } }

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);
}
