I am working on an application to view my Desktop directory into a TreeView form (which I already done). But my question is, how do I start implementing code to search the entire treeview (including Parents and Childs Nodes) for an item that ENDS WITH ".EXE" only then displays me a message box for the particular item. Thank you.

@Wes Aday Thanks for your help, but can you write the code below? Because the code that is on MSDN is too general.

No sorry. There is no reason for me to write code for you. How about you give it a try yourself?

"I tried" and "no luck" does not tell us anything about your problem. You asked the question and got the answer. We can't see that you have made any effort at all to solve whatever your actual problem is. "Gimme code" is not a question or a description of a problem. Just giving you code leads you to believe that people here will just write code for you for free and you will come to expect people to do your work for you instead of you doing it yourself.

TreeView? Which one? Full type name, please. And please explain what is your problem? If you created a tree view, you should know how to access these nodes.

I have already created my TreeView and I taught it to view the contents of my Desktop as a TreeView in my C# application. What I am asking for is how am I going to be able to search the entire TreeView list to check if there are nodes ending with ".exe" only. If so, I want it to be displayed as a Message Box. Thanks

Still you are not answering which TreeView do you mean. And you are not explaining your problem. Did you even try to traverse the tree view nodes?

The treeview that has nodes with it...

Okay, should I understand it that you have no idea what are you using? But then you won't be able to get any help.
I asked the most elementary question, the type of the "TreeView" class, its full name. There are several classes names like that, so which one do you mean? And what's your problem?

I wouldn't search at all. Rather if I know beforehand what I want to find (as you do), I would also create a cache of those items.
In this case I might create a Dictionary<string,List<TreeNode>> and whenever I add a TreeNode to the TreeView I would also put it in the appropriate List, then finding "all the EXEs" is as simple as accessing the specified List in the Dictionary.

Do the work once, up front. Think of it like a card catalog at the library.
