Don't repost your question, BTW Tarun showed you a way how to use linQ with IEnumerable collections. That is an acceptable answer for your question.

But would you mind providing some more details why you want linQ here. What the result in Tarun's answer can be the same groupBox1.controls. To search a control inside? groupBox1.controls.find("Button1", true/false);. But you may be having specific reasons to use LinQ here. I am just interested to know the reason. Good to know different thoughts :)

Solution 1

This is how I did :

C#

IEnumerable<control> controls = from Control control in groupBox1.Controls
                                select control;</control>

Now you can enumerate over controls like this :

C#

foreach(Control control in controls)
{
  //Do your operation here.

}

I am not much aware of the answering forum but what I notice while 5d to your answer is, it automatically selected as answer!! Does this happens? Cause when I visited 1st time to reply 'SAKryukov' this answer was in White Background but now it turned in Green.

Tarun.K.S 28-Apr-11 9:04am

Thanks for the 5 buddy! Actually the answer didn't get accepted or else the "Solution1" tab would also get the green color. For example, check out this answer : http://www.codeproject.com/Answers/186410/Close-button-coding-warning-message.aspx#answer1

Tarun.K.S 28-Apr-11 9:07am

Also check out this answer : http://www.codeproject.com/Answers/184875/check-network-printer-is-online-or-not.aspx#answer3, OP didn't accept it but it became green because I got 3 or more upvotes for the answer.

Gandalf_TheWhite 28-Apr-11 8:23am

Yup! It have had happened to me with Tarun as well and there was same situation like this, and There is nothing wrong to hesitate as it is thankless job and if one forget to 5d that he/she much deserves for he efforts.
Great Going Tarun, I appreciate you. 5d to your answer.

Tarun.K.S 28-Apr-11 9:08am

Lol I remember that! ;)
Thanks a ton again buddy for the appreciation. Do participate more in Q & A forum. :)

You're welcome mate.
It's hard to roam in this world(Q&A) compare to our GIT. As to roam here one need to concentrate more and had to try their best to justify the solution that demands.In GIT just a glimpse of post is enough to understand about the message, also in somewhat busy schedule it is easy to ream in GIT as that do not require much attention.

Tarun.K.S 29-Apr-11 9:05am

True man, one has to spend a considerable amount of time to answer the queries here. SA has done a tremendous job here in CP, his contributions to Q & A is admirable.

Sergey Alexandrovich Kryukov 28-Apr-11 12:17pm

Gandalf, are you addressing to me? I'm not sure.

I have a strong feeling that you misunderstand English expression "do not hesitate".

It is purely positive and means invitation to do something (reminding) without a doubt because there is no shame in doing so.
Please, before sending a rant consult the dictionary: "hesitate", "rant", "shame"... I do it all the time.
If you think I'm wrong, please don't hesitate to let me know.

Tarun.K.S 29-Apr-11 8:02am

Oh no SA you misunderstood what he said. :)
Actually he was supporting your idea that one should not hesitate to remind. Check his reply, he responded by saying "Yup", which meant that he agreed what you said. He was telling so because the same happened with him too. He forgot to give me a 5 which I reminded him. :D
Hope the air is clear now.

Sergey Alexandrovich Kryukov 29-Apr-11 10:57am

Thank you, Tarun. No problem.

Gandalf_TheWhite 29-Apr-11 8:50am

Nope actually I didn't understand in that -Ve manner, Actually I appreciate your post as well. I was too positive in that post.

Sergey Alexandrovich Kryukov 29-Apr-11 10:57am

"-Ve manner..."? Everything is OK, right, Gandalf?
