.Net Drag and Drop
-
Hi, i'm currently working with drag and drop between windows explorer and a form using the .net drag and drop. I have a file and a directory with the same name and i want to drop one of them from explorer to my form. Is there a way of telling whether the item i'm dropping into the form is a file or a directory? Thanks in advance :)

Doesn't it deliver a path ? File.Exists will tell you.

yep, it delivers the path, but the problem arises when there's both a file and a directory with exactly the same name. If I use File.Exists and I'm actually dropping the directory then I would get the wrong item.

You will need to load the file in as a FileInfo and then look at the attributes to see if it's a directory or not...
FileInfo f = new FileInfo(strFileName); if ((f.Attributes & FileAttributes.Directory) == FileAttributes.Directory) { // Delete it } else { // Ignore it - or whatever } -

You CANNOT have a file and a folder with the same name in the same location. However, as already suggested, you can use the attributes to find out if the entity in question is a directory.

This is true, I never knew that, I just tried it. But surely your file would have an extension which makes its filename different to the folder's filename anyway.

You can have a file without an extension. You can equally well have a folder with an 'extension'.

True that. What I meant though was that your file will more than likely(almost definately) have an extension and your folder will not. Why would anyone create a file without an extension or a folder with one for that matter.

We're splitting hairs, but as a developer, I would want my code to be as robust as it should. I wouldn't ignore scenarios that are unlikely. One man's food is another's poison.
