Sort Method using IComparer Interface

Posted By:      Posted Date: October 17, 2010    Points: 0   Category :ASP.Net

Hi All,

I am trying to implement sorting in list using IComparer Interface.

If any two values are equal, then there order is not maintained in the list

after using sort function.

Say, I am sorting an Employee object based on Department ID like,

Employee 1 -> Dept ID = 100, Name = "John" 

Employee 2 -> Dept ID = 100, Name = "Peter" 

Employee 3 -> Dept ID = 100, Name = "Wills" 


The output of this after sorting based on Department ID should be

100, John

100, Peter

100, Wills

but the output is

100, Wills

100, Peter

100, John

where the order is getting changed if the values in the sort column are equal.

Is it possible to maintain the order if the elements are equal.

Reflection question - how to tell if a method is defined in an interface?


OK so the Reflection namespace has tools so you can tell if a method has a base definition in a class (MethodInfo.GetBaseDefinition().DeclaringType). This way for instance I can query the ToString method of my favorite class and see that yes, indeed this inherits from System.Object.

I also can detect if a method is an explicit interface implementation, by checking the name of the method (methods representing explicit interface implementation will have the fully qualified name of the interface pre-pended to the value of the Name property) so I'm okay there.

But what about plain ole interface implementations? How do I get this info?

Thanks if you can help!

SVCUtil changing CallBack interface method


I am creating a WCF duplex callBack structure, with a WPF app registering with a WCF service, and the WCF service using a CallBack in the WPF app to pass data from time to time. The interface for the callback in WCF is simple:

  void DataUpdate(string updatedData)

yet when I launch the service and run SVCUtil.exe, the CS code changes the callBack interface to

  void DataUpdate(DataUpdate request)

What is the cause of this? How can I get the proper structure to show in the SVCUtil output?



Thinking about new C# method prototypes: object as dictionary

I recently had to write a small Flickr API. I know many .Net API for Flickr already exist but I needed one for a Silverlight application. Whatever, it's only about building some querystrings so I did it by myself. It's been an opportunity to think again about a classical question: how to pass parameters to a method ?

Imagine you have a generic method to call some Flickr functions.

Jscript error: Object does not support property or method


 Hi, i have little knowledge on javascript but i need to use this code get from somewhere for a jquery to work.

I face this "Jscript runtime error: Object does not support property or method" whenever im trying to run this page.

In my experience, im get this error msg 9 out of 10 times i use javascript in my system.

Im using Microsoft Visual web developer 2008, i wonder if this is related to my problem, i not sure there is anything i need to add as reference or update anything.

But anyway, in short, i just couldn't use javascript code when using this development tool because of this sort of error.

Anyway, it happen that last time i tried use the same type of jquery code in another project and it seems to work well without an error.

But now when im try to use it again in this recent project i created, it come out with this error and i have no idea how to solve it even look through google and this forum.

It doesn't really seems like its the code problem itself although im not sure, because any javascript code just couldn't work.

So below is my code that i need to use.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" ></script>
<script type="text/javascript" src=&quo
