Re: Tell if a path is a FILE or a Directory - C# Discussion Boards

Good Day,

If I want to check if a path is a File or Directory, I always use the Path.HasExtension function. If it have an extension, it is a file. Otherwise, it is a directory.

Just recently, I found out that this is not really effective for Files that doesn't have an extension and for directories that have an extension.

So How can I really really tell if a path is a File or a Directory?

PS: I can't use File.Exist or Directory.Exist.

Thanks! Big Grin | :-D

Well you could use...

Damn, why not?

How about

DirectoryInfo DI = new DirectoryInfo("C:\\thing");
if(DI.Exists)
  //its a folder
else
  //its a file

It's exactly the same, but different Roll eyes | :rolleyes:

I can't think of any other way of the top of my head.

Well, the path that I am testing does not really exist. It's hard to explain.

Just think of it as a "programming exercise" given in school and you have to type a random path and tell if it is a file and a folder.

Your teacher is a retard. If the file doesn't really exist, and you can't use the presence of extensions to tell, then there is no real solution.

No, its not a school activity. I just made that up to simplify the matter.

Well, this is the real scenario...

I have a function that "ROLLBACKS" files and folders. I have a special routine for files and special routine for folders. Those files and folders does not exist yet, that's why I can't use the .Exists() method.

I just want a function that accepts a PATH and returns if it is a folder or file.

Sorry for the confusion.

Not possible, for the reasons stated. Your best bet is to assume an extension means it's a file.

Thank you for your time Mr. Graus. Smile | :)

As has been pointed out, there is no way to tell if a path is for a directory or file UNLESS there is a directory delimiter (slash) at the end. This isn't guaranteed by almost any function, though.

Anyone who thinks he has a better idea of what's good for people than people do is a swine.

Hello,

I have a main form that contains many form. When i am trying to close the main form by the X control box button, the onformclosing event of the child forms are launched before the main form event (onclosing) are launched.
How can i capte the X button closing in the mainform first?

best regards,

dghdfghdfghdfghdgh

The main form is closing it's children first. This is logical. I am not sure if you can do anything about it.

You can check the FormClosingEventArgs in FormClosing. Allows you to cancel closing the form. I don't really know if the child forms will stay open, but it sounds logical that they will.

I used the above code Flickering is not completely removed, still its slightly fliickering. Is there any way to Remove complete flickering of Waveform.

Whenever the form is resized or the horizontal scrollbar is moved, the waveform starts flickering.. plz do help me..

I create a winform by c# 2003. The form's classname like "windows.forms.app3",I must change the it to the particular name that like "myForm". Thanks for you help.

If you use F2 to rename the file in the solution Explorer, I think it will rename the class for you. Yo ucan also right click on the name and rename it via the refactor menu. Finally, you can just do a global search and replace.

Sorry, maybe my question is not clear. The classname is not my class name. use the tools SPY++, you can find the form's classname is "windows.forms.app3". i want change it.

well, why on earth would you want to do that ? I doubt you can.

My winform is controled by other software. It use windows api function "sendmessage" send the windows message to my form. The function need 2 parms "form's classname & form's title".

so i must change the classname to specific name like "myForm".

No, you don't need to do that. SendMessage takes a HWND, you can FIND the hwnd based on name or title, using different APIs.

Only works on a "modern" IDE. VS 2003 didn't have the fancy refactoring - this was introduced in 2005.

Deja View - the feeling that you've seen this post before.

Which is why I also said 'search and replace' :p

Override CreateParams, and set the class name yourself. Not sure if it will give you an exact name though, but it's worth a try.

Hmm. Doesn't work.
