Why Use Reference Of Abstract Class To Create Object

Jul 22, 2010

Why do we use the reference of abstract class (or base class) to create object of it's sub-class. eg: TextWriter is the abstract class for StreamWriter & StreamWriter.

TextWriter writer = new StreamWriter();

why can't we simply use :

StreamWriter writer = new StreamWriter();

Recommendations For Abstract Class Vs Interfaces?

Dec 21, 2010

From the following URL i got some doubts about the Recommendations for using Abstract class vs interfaces


1. If you anticipate creating multiple versions of your component, create an abstract class. Abstract classes provide a simple and easy way to version your components. By updating the base class, all inheriting classes are automatically updated with the change. Interfaces, on the other hand, cannot be changed once created. If a new version of an interface is required, you must create a whole new interface. { Is there any example for this t ounderstand throughly ?} If you are designing small, concise bits of functionality, use interfaces. If you are designing large functional units, use an abstract class. If you want to provide common, implemented functionality among all implementations of your component, use an abstract class. Abstract classes allow you to partially implement your class, whereas interfaces contain no implementation for any members. { Is there any example for this t ounderstand throughly?

Use Of Abstract Class In Shopping Portal?

Jul 27, 2010

I just want to know that how can I utilize the concept of Abstract class, virtual class etc. in my shopping cart website. I have read the tutorial out there on internet and I saw some examples too, but those examples are so general that they dosen't fit into real world scenerio like I am searching for a shopping website. Same questions again and again comes to my mind that why to made a class only to give the declaration of methods and property.

Creating An Abstract Class That Will Define All Database Manipulation Methods To Implement

Mar 3, 2010

I am developing a couple of small ASP.NET application and would like to know what pattern. approach do you use in your projects.

My projects involve databases, using Data access and Business logic layers.

The data-access approach that I was using so far is the following(I read in some book and liked it):

For DAL layer:

Creating an abstract class that will define all database manipulation methods to implement.
The abstract class will contain a static "Instance" property, that will load (if instance == null) an instance (Activator.CreateInstance) of the needed type (a class that implements it).

Creating a classes that implement this abstract class, the implementation will be according to the databases (SQL, mySQL and etc) in use.

With this I can create different implementation according to database in use.

For BLL layer:

A class that encapsulates all all retrieved fields , and static methods that will call the DAL classes.

Forms Data Controls :: Binding Repeater To List (of Abstract Class)?

Feb 18, 2010

I am attempting to bind a Repeater (but it could be a GridView or ListView) to a list of objects. The List's type is an abstract type, which has two different classes derived from it, both with different properties. Because they have different properties, I cannot just have one ItemTemplate. If I bind a control to a property of one type of class and the other type doesn't have it, it throws an error.

Here's where I'm at:

I cannot use <% if (whatever) { %> some stuff <% } else { %> some other stuff <% } %> because I cannot access the databound item to make the choice based on its type. I cannot use the <%# %> syntax, which lets me use the databound information, because you cannot code logic like if...then...else. I cannot (rather not) call a function and return a string with the code because what I want to render is complex and contains further nested databound controls. Has anyone found an ingenious way of doing if it is this type of object, display these controls, else display these other controls?

C# - Class Structure With LINQ, Partial Classes, And Abstract Classes

May 17, 2010

I am following the Nerd Dinner tutorial as I'm learning ASP.NET MVC, and I am currently on Step 3: Building the Model. One part of this section discusses how to integrate validation and business rule logic with the model classes. All this makes perfect sense. However, in the case of this source code, the author only validates one class: Dinner.

What I am wondering is, say I have multiple classes that need validation (Dinner, Guest, etc). It doesn't seem smart to me to repeatedly write these two methods in the partial class:


This doesn't "feel" right, but I wanted to check with SO to get opinions of individuals smarter than me on this. I also tested it out, and it seems that the partial keyword on the OnValidate method is causing problems (understandably so). This doesn't seem possible to fix (but I could very well be wrong).

Architecture :: Interface, Abstract Or Inheritance?

Oct 7, 2010

I have a table which houses two entities. StaticProgram and DynamicProgram. There is one column in that table called ProgramType which determines if a program is of Type static or Dynamic. Though these two entities are stored in one table (I am guessing because the primitive fields for Static and Dynamic programs are exactly the same) but from a business point of view these are two VERY different entities.

So, I created two Classes StaticProgram and DynamicProgram. However, I donot want to create two seperate Data Access Classes because it is going to be the exact same code replicated twice. I tried creating a "Program" class as base class and inherited StaticProgram and DynamicProgram classes but down casting is not supported so I can't return a "Program" object from the data access class and cast it to "StaticProgram" class.So, what are my options? Can I create an IProgram interface and have StaticProgram and DynamicProgram implement that interface and have my Data Access class return IProgram?

ADO.NET :: LINQ To SQL Inherited Classes With Abstract Functions?

Aug 16, 2010

I'm building a web app that will keep a events in a database and add the event to a Google calendar on insertion.

I have three types of events, PendingEvents, ApprovedEvents, and DeniedEvents. I'm using single table inheritance through LINQ-to-SQL, with the Event class being abstract and the 3 types inheriting from it

Each type of Event is stored in calendars differently. I would like to use an abstract member function in Event called AddToCalendar.

I'm trying to set this up in a separate class file because I'm using the LINQ-to-SQL designer and I don't want these to be overwritten if I change the LINQ diagram.

However, I get an error from all three inherited classes that "'WebCal.ApprovedEvents' does not implement inherited abstract member 'Edu.Northwestern.WebCal.Event.AddEventToCalendar()' WebCalendarWebApplication1App_CodeWebCalDataSource.designer.cs"

It looks like it won't check my outside file and only looks at the designer.

The non-designer partial class file looks something like this:

public partial class WebCalDataSourceDataContext : System.Data.Linq.DataContext

i have the below code i want to put in a global method set as static so that i can build a couple tree views on my web app. now i have each building its own tree view using the code below. i was thinking to make a global static method to generate the node structure such as this and then just assign them to the tree view in my pages... or something like this. i dotn care about the details of the actual solution as long as i can have a single method to call like "buildTree()" that will be able to be used to bind the tree view controls to.toughs?

Create New Class For Each Procedure?

Jul 23, 2010

All I want to do is learn how to create a class procedure. And then. How to call it. As an example, A + B = C is the procedure. I would create a class. Right? Then do I name the procedure and put it in the class? Or create a new class for each procedure? Then I would want to, on a local level, substitue values for A & B to return C. So, if the public procedure exists, how to I call it? I know that this is really simple stuff, but I need examples to be simple.

How To Create A PageBase Class

my problem is that I can't seem to pass the information captured from the query to the page. I get problems such as can't convert string type to literal and I need to declare a new keyword to an object.

C# - Cannot Create UserControl In Class

Jan 26, 2011

My ultimate goal is to create a UserControl in a class in my App_Code folder and render the html from that into a string.

The rending of HTML can be done using this example I believe:

How do I get the HTML output of a UserControl in .NET (C#)?

My Question:

I created my user control

public partial class Controls_MyUserControl : System.Web.UI.UserControl

I've registered it in my web.config

<add tagPrefix="UC" src="~/Controls/MyUserControl.ascx" tagName="MyUserControl" />

I can reference this on a page just fine

<UC:MyUserControl ID="MyUserControl1" runat="server" />

Yet when I try to create an object of this control type in a class (in my app_code folder) it doesn't allow me.

Controls_MyUserControl dummy = new Controls_MyUserControl();

The potentially strange thing is when I put this code into a code behind of a page, it works.

what I need to do to have the usercontrol to be able to be created in my class in the app_code folder?

My guess is, is that I need to reference the control in a "using" statement at the top, but I'm not sure what that'd be.

It's not in a namespace to my knowledge (at least there's no namespace, in the code behind of the actually user controls). Though I'm not sure if it inherits one from the System.Web.UI.UserControl.
