Your question makes no sense at all. How do we know what your requirements are? How it will be used in your application? There is no "best", only what works for your requirements and skills.
Failure is not an option; it's the default selection.

OK,
I have a pair of a kind(key , val).
I need to store them in sorted order by the key value.
I need the option of searching also.
Thanks.

If you need fast lookup based on the key value, a Dictionary is highly recommended. It is fast, however it does not preserve order.
If order is most relevant to you, you might opt for a List of KeyValuePair objects. However I can't easily imagine a situation where I would. Alternatively, you could go for a Dictionary plus a List that holds the keys in the order you want them. I do this occasionally.

Using the KeyValuePair class[^] should help you solve your problem.
|
|

|

You have stated in another response you want it to be sorted too?
if so, how about the SortedDictionary[^]?
|
|

I'll chime in with the rest - SortedDictionary<of keytype,="" valuetype="">. I've used it extensively in VS 2008 projects for just this purpose, where I wanted key lookup of values but also wanted to iterate through the list in key order.

Je veux créé un "Web Browser" c'est a dir un navigateur intenet en VB (Visual Basic) qui ne serais pas basé sur le Controle Actve X de Intenet Explorer (IE) mais sur celui que je vais créé. Alors je vous demande comment le créé (Mon webrowser control)?

I created a "Web Browser" is a dir intenet browser in VB (Visual Basic) that would not be based on the Control Actve X of Intenet Explorer (IE) but the one I will created. So I ask you how created (my webrowser control)?
|
|
|
|
|
What will be the functionality of your browser?
Will the Control do more than just paint the page? (e.g. have buttons, menus, ...)
Will it support HTML4, HTML5, CSS, CSS3, JavaScript, ...?
Why do you want to do this? I could come up with a few reasons, however I'm curious about your reasons.
And why did you ask in French, as your English is clearly better than your French, at least as far as spelling goes?

Can any one help to limit the internet usage of the computers connected in a LAN network.

Yeah, it's called a proxy server. Since you haven't asked a more specific question, that's about as specific as the answer is going to get.

Hi, can anyone tell me which .NET framework is superior to work on?

IMO, its always best to use the latest (ease of use is something that depends on how fast you can learn the new features of the version).
|
|
|
|
|
|
|
All of them. It depends on the app requirements and the lowest common denominator for platform support.

.net 3.5 Version Is Easier to use
|
|
|
|
|

The answers given by Abhinav and Dave Kreskowiak are absolutely correct.
I want to add that
.NET 1 and 1.1 are now obsolete.
Even though Visual Studio 2008 and above provide multi targeting feature, there is no support for .NET 1 and .NET 1.1.
The size of .NET 2 is less, around 22.5 MB. With the introduction of generics and other improvements in .NET 2, I think, if there is a concern about the size of deployment, .NET 2 can still be used, if there is no specific requirement for new features available in the later versions.
For some features like, extension methods and LINQ to objects there are certain work arounds to use them in .NET 2 also.

I am developing an application called mysql query browser in C#.net. I have to mention hardware and software requirements in my SRS.But I dont know how to know what are these and what is the reason behind this....so plz tell me....I am using .net 3.5..thanks...

The reason is very simple.
Imagine trying to run the application you are building on a machine that does not have the framework installed or on a system that does not have Windows.
It wont work!
As a result, you need to list out the minimum requirements that your application needs to run.
