So, hypothetically, I'm building some sort of real estate application in C#. For each type of property, I'm going to create a class such as ResidentialProperty and CommercialProperty. These two classes as well as all other property classes will share some common properties, such as Id, Title, Description, and Address information. What I...

for reasons beyond the scope of this discussion (say xcopy an aspx page to a directory, so that we dont have to get a new build out) , we would like to implement an interface in an aspx page.Say, if the page is myPage.aspx, it is usually your class in the codebehind mypage.aspx.cs which implements the interface. When I do something like...
Hi All, I would like to know the significant use of Interface. I have read many articles but not getting clearly the concept of interface. I have written a small program. I have defined the Interface Itest.Class(Manager) has implemented the Interface.Another class(Employee) has not implemented interface. But defined the same method(DoS...
I wonder if it is in any way possible to specialize generic interface methods somehow in C#? I have found similar questions, but nothing exactly like this. Now I suspect that the answer is "No, you can't" but I would like to have it confirmed. What I have is something like the following. public interface IStorage { void Store<T>(T ...
Hi all, I want to have an interface A parameterised by T A<T>, and also want every class that implements it to also implement Comparable (with T and its subtypes). It would seem natural to write interface A<T> extends Comparable<? extends T>, but that doesn't work. how should I do it then? ...

I ran into some code today that I found questionable. Here's a simplified example (not realistic). public interface IListable { //returns first n items from list public ArrayList getFirstNThings(int n); //returns last n items from list public ArrayList getLastNThings(int n); } Then there's an implementor like so: pu...
I have some code that works without having referencing outlets for the controls - just event ties in Interface Builder. Is this ok and is a referencing outlet only necessary to change the state of a UI control? Thanks. ...
Hello, I need to develop an application which has a interface which implements methods of 3 protocols. Assume protocol A extends protocol B and protocol C, and interface implements protocol A. This is how my code looks, // This is in MyClass.h file #import <Foundation/Foundation.h> #import <UIKit/UIKit.h> #import "protocol_A" @interfac...

I've been reading through the book Working Effectively with Legacy Code and I've been playing around with the concept of overriding difficult to test methods in unit tests via the creation of a fake. I put together an example of what I thought would work and it ended up behaving differently than I had been expecting. I think I've just di...
I know the interface of the .class file lets say Boolean xy(); is the only method. I want to execute the method of an unknown .class file which implements that interface on my server. The Method should be able to call some Methods of my classes. How can i be assured or test that no dangerous stuff is executed in the method? ...
I was wondering why the sort method of the Arrays class is asking for a parameter of type Object[]. Why the parameter is not of type Comparable[]. If you don't pass a Comparable[] it's generating a ClassCastException. Why ... public static void sort(Object[] a) and not public static void sort(Comparable[] a) ? Thanks ...
In PHP, can I specify an interface to have fields, or are PHP interfaces limited to functions? <?php interface IFoo { public $field; public function DoSomething(); public function DoSomethingElse(); } ?> If not, I realize I can expose a getter as a function in the interface: public GetField(); ...
Hi, Firstly, I want to apologize for my English, not my strongest side. To the question.

Anyway, I get an error when I try to use my interfaces and SimpleReposit...
