I have a class with 2 interfaces, and I have some superclasses with subclasses, I would like the superclasses to inherit both interfaces. if I just reference the class the interfaces its in, will it work? ie SuperClass : Myinterfaces
here is the class with the interfaces
public class Myinterfaces
{
public interface IBakeable
{
int OvenTemp { get; }
}
public interface IAccounting
{
int Cost { get; }
}
public enum Colors
{
red = 1,
blue,
yellow
}
}
and heres an example of the superclass
public class CeramicsSuperClass : Myinterfaces
{
public string ItemName { get; set; }
public int Cost { get; set; }
public int OvenTemp { get; set; }
}
public class Vases : CeramicsSuperClass
{
private int _BaseDiam;
public Vases(int diam)
{
_BaseDiam = diam;
}
}
You are doing in a wrong way to implement multi-interfaces for a class, try this instead:
public class CeramicsSuperClass : IBakeable, IAccounting {
public string ItemName { get; set; }
public int Cost { get; set; }
public int OvenTemp { get; set; }
}
A class can inherit from only another class but it can implement as many interfaces as possible. When a class inherits from another class and implement some interface, the base class should be listed first, then the interfaces go after like this:
//class A inherits from class B and implements 2 interfaces IC and ID
public class A : B, IC, ID {
//...
}
Simple answer: You can inherit mulitple interfaces, not multiple classes.
public interface InterfaceA
{
string PropertyA {get;}
}
public interface InterfaceB
{
string PropertyB {get;}
}
public abstract class BaseClassForOthers : InterfaceA, InterfaceB
{
private string PropertyA {get; private set;}
private string PropertyA {get; private set;}
public BaseClassForOthers (string a, string b)
{
PropertyA = a;
PropertyB = b;
}
}
public class SubClass : BaseClassForOthers
{
public SubClass (string a, string b)
: base(a, b)
{
}
}
