There is no direct way to do it - the GetFiles method does not provide an "except files matching this" option.
Personally, I would do a "straight" GetFiles, then post process the list to remove the exceptions: in your case it is a pretty simple loop or Linq statement - remember that the Path class will extract the file name and extension separately for you with the Path.GetFileNameWithoutExtension[^] and Path.GetExtension[^] methods

I am new to web development. I am trying to write a web application that a user can click on 2 boxes and program should draw a line between them. I have no clue on how to start this project. Any help is much appropriated.
How is google map written? how can they draw shapes and users can click on it? Would like my app to behave the same way.
Thanks in advanced.

Are you really sure you wrote this in the right forum? You wouldn't do this using C# - you would use JavaScript for this.
|
|

Thanks for the response Pete.
So what you are saying is this functionality is not possible with c#. I though I could do this in C# since I have done similar functions with a Win Forms.
What I thought I could create a embedded object (such as ActiveX) and go in that route. So that was a wrong thinking.
So I should try this in JavaScript or HTML5?

If you don't just want it to run in IE on Windows, you shouldn't use ActiveX. If you look at Google Maps (for instance), you will see that they make extensive use of JavaScript.

A couple of points. First, when answering questions in the forums, it is best not to use text speak. This is looked on as unprofessional, and will often result in people downvoting your answer.
Secondly, it is important to consider what the user is actually asking. He has asked how to draw on a web page, and your answer has absolutely nothing to do with drawing on a web page. I commend you for wanting to help out, but it's better not to answer than to give completely the wrong answer.

I'm working with an Infragistics UltraTree. The types loaded into the tree are each stored on the node's Tag property. I want to activate a node based on a particular instance of a type.
So far I have:
public void SelectNodeByEntity<T>(T Entity)
{
UltraTreeNode node = GetNode(UltraTree1.Nodes, Entity);
if (node != null)
{
UltraTree1.ActiveNode = node;
}
}
private UltraTreeNode GetNode<T>(TreeNodesCollection Nodes, T Entity)
{
UltraTreeNode retVal = null;
foreach (UltraTreeNode node in Nodes)
{
var entity = (T)node.Tag;
if (entity == Entity)
{
return node;
}
else
{
if (node.Nodes.Count > 0)
{
return GetNode<T>(node.Nodes, Entity);
}
}
}
return retVal;
}
But it won't compile on the line indicated above with "Operator '==' cannot be applied to operands of type 'T' and 'T'".
How do I pull the object off the tag, convert it to type T and compare it with the type passed in to see if their the same?
Thanks
If it's not broken, fix it until it is

Try using .Equals instead. == isn't allowed when comparing generic types (in the same way as you can't use ++ or --).
|
|
|
|
|
That did it. Thanks Pete!

Not a problem. I'm glad I could help.

Just the bug left to be corrected now...
(You don't want to terminate the search if the current node is not the entity you're looking for AND it has children, but you are. Instead, if searching the subtree yields null, you want to continue with the next node.)
|
|
|
|
|
... or for a reference equality check,
if((object)entity == (object)Entity){ ... }
|
|
|
|
|
I've never looked into it and I don't have Reflector here - is there any advantage to casting to object and using the equality operator compared to object.ReferenceEquals(a, b) in your opinion?
|
|
|
|
|
I don't think there's any difference, it's a matter of which you find more readable. I like to see == because that can be seen to be an equality check at a glance, whereas a method call you actually have to read the word to find out what is happening.

It's quite possible that they can, but you need to give some more specific details about what problems you are having, it's unlikely that anyone will be able to guess.
One of these days I'm going to think of a really clever signature.

i want to use weka libraries to use some filter and classifications
filter like Replace Missing Values and others?
|

|

Okay, so you have stated what you want to use, but you haven't actually stated any problems here - or shown us any code that you need help with. What, exactly, are you expecting from us?
|
|
|
|
|
as you have said i know what i want to do
but the problem is that i don't How to Do So?
so if anybody might have a little experience can help me ?
thanks

Well, this[^] tells you what you need to do to set up WEKA with .NET.
This[^] is a handy place to start with WEKA (links to FAQs, etc). Beyond those links, I don't see how we can help you without actually writing your application for you.

I see the problem. You have a syntax error there.
