Jan 4, 20111. Why we need override the methods? (i know what is ovwrriding but why ?)I gave answer to extend the functionality of method is it right ? again sub question was ,
Class A
{
method1()[code]....
if i can create the object of Class A in class B and can invok the method then why need to override metho here ? in fact i could not get this question , because i think both concept are irrelevat with each other. why he asked this ?same for overloading.
why we need overloading?If MSIL is there then what is need of CLS(common language runtime ) and CTS(common type system)List the 5 resposibilities of CLR (I explained only CTS,CLS,Garbage collection) was i right . what else?
What is role of abstraction and encapsulation? what the difference between them ? In which situation we have to devlop abstration and encapsulation.
6.What is included in signatures , when we said overloading means same name but different in signature. Is access modifiers included?

10.In which scenario we need to implement interfaces?
11.In which circumstances we need to develop abstract classes?
12.Is class is static, means we can not create its instance, we can not derive it then how can we use method containing it? Why we need static classes?
Please guide me about these all question

C# - Hierarchal Data Context And Abstraction?
Mar 31, 2011I am creating a core library for one of our internal project. This core library supposed to contain some abstract classes and generic classes which will then be extended by specialized projects. For example, There is an AbstractPerson class with standard properties and methods for a Person class while another project will implement a Person class which will inherit from the AbstractPerson class to add project specific functionality.
Now we need to impelment DAL for this common and specialized projects.As most of operations are generic so i want to include them into core library as Repository classes. However, Repository classes need to access LINQ dataContext. Which is generated from the specialized databases. Hence there is no dataContext available in Core library to work. So how could i can create a common repository classes for generic methods which can reside in the common library.
C# - Class Encapsulation With Repository Pattern?
Oct 18, 2010I am sort of using a repository pattern to extract information from a database. I have two classes, report and reportRepository.
The trouble I have is that since reportReposity has to fill in all the details for the report object, all the members in the report have to be publicly accessible.
Is there a way so that I can ensure that only the repository class can access some of the methods of the report class and only it can set some of the properties that other classes cannot, sort of like what friend does in c++. Or is there a completely different way of handling this situation?
I am using C# in ASP.NET 2.0
Differentiate Between Two Class Of Same Name In Different Css On Same Page?
Apr 24, 2010on my asp.net page i am linking 2 css files which are used by 2 different controls but the main problem is that one class name is same in both so they are conflicting with each other, how can i distinguish between them. Both are of jquery, 1 is slider control and another one is time picker control. and they are conflicting on their background image as i want to change background image of slider control's scroller. code for using slider :
<div id="time1" style="float: left; width: 100px" >
<code>$('#time1 input').ptTimeSelect({ popupImage:
'<img alt="Select" src="../images/icon_clock_2.gif"
style="border-right: 0px; border-top: 0px; border-left: 0px; border-bottom: 0px" />'
}); </code>
<div >
<input id="s2Time1" runat="server" name="s2Time1" readonly="readonly" style="width: 60px" />
</div>
</div>
below code is for time picker :
<div id="time2" style="float: left; width: 100px">
<code>$('#time2 input').ptTimeSelect({ popupImage: '<img alt="Select" src="../images/icon_clock_2.gif"
style="border-right: 0px; border-top: 0px; border-left: 0px; border-bottom: 0px" />'
}); </code>

Sep 10, 2010I have 2 xml documents that I need to find the difference and then save it back to an xml file. I already have the code to get the difference, I am just lost on how to save the IEnumerable back to xml. I tried to stuff it into an XDocument, but got a conversion error.
Code:
Dim xDoc As XDocument = XDocument.Load("doc1.xml")
Dim xDoc2 As XDocument = XDocument.Load("doc2.xml")
Dim result = xDoc2.Descendants("Contact").Except(xDoc.Descendants("Contact"))
'Tried this but It blew up.
Dim resultDoc As XDocument = result
resultDoc.Save("result.xml")
Am I going to have to rebult the xml document and manually add the elements? Or does LINQ support converting back to the same schema?

Architecture :: How To Design A Centralized Business Or Service Authentication Architecture
Sep 22, 2010i want to create a centralised business or Service authendication architecture in .net. for example, we have a clients like c1, c2, c3, c4, ... etc. everybody logins seperatly as well as grouply. ie, if client "C1" logins [with login authentication] he can access c2 , c3, c4 also without login authendication. So its like a google. if we enters gmail account, we can access orkut, picasa like that.. i need the cetralised architecture.
And, client "c1" seperately asks seperately how will be the authendication architecture.
so give me the single solution for both these two scenarios. how will be the architecture for these two and how is the Data Base (Login) Structure.
Architecture :: Entity Model Design Framework And N - Tier Architecture
Dec 25, 2010recently i've studied on ADO.NET's Entity Model Framework and say 'wow' as ORM is one of the fevourite pattern i practice..but suddenly i've come to an ambiguous situation when i'm going to start. i usually follow the following 3-tier architecture..
1. UI Layer
2. BLL - business logic layer
3. DAL - Data Access Layer
a. DTO / DAO
b. Gateway (contains the sql query/stored procedure and connection with DB)
now when i'm going to use the Entity Model Design,where the DBML/ .edmx File should be placed? Because many a times i'm using the DBML file as DTO because of the mapped objects.. in the same time, sometimes DBML ( .edmx file in .NET 4.0) contains CRUD methods and stored procedured method as well as methods with different selection operations,- which should be in Gateway. so where the .edmx file should be placed !?!! IN DTO namespace !? or in Gateway namespace!
moreover sometimes there is no need for the BLL which breaks the rules of inter-layer-communication (UI > BLL > DAL.Gateway)! what makes me confuse is, what should be the ideal n-tier architecture when i'll use the ADO.NET Entity Model Design Framework
