hi
i am trying to write a program that search a folder and all its subfolders for finding zip or Rar files that are in the folder and there is a folder named exactly like the zip files beside it. after finding them it send the path of the files into a listbox. but i have problems with importing these addresses and deleting the directories or the files(based on the user choice). i know that there is a code like this for doing this but it doesn't works for me.

C#

System.IO.Directory.Delete(@"C:\Users\Public\DeleteTest", true);

please answer just simply i am not that much pro in programming. and i am working with visual c# so please don't use command line codes.thank very much

I'm not positive whet your problem is exactly, but I tried this:
Create a folder in my Temp directory called "DELME"
Create a zip file in my Temp directly called "DELME.ZIP"

The following code worked:

C#

Directory.Delete(@"D:\Temp\DELME", true);

The folder was deleted.
Recreated the folder.

C#

Directory.Delete(@"D:\Temp\DELME.zip", true);

The command threw an exception, as DELME.zip is not a folder.
Checked both present.

C#

File.Delete(@"D:\Temp\DELME");

Threw an exception - unauthorised access (it is a folder, so yes it would fail).

C#

File.Delete(@"D:\Temp\DELME.zip");

The zip file was deleted.

All of that looks fine to me: what are you doing that could be different?

i know this codes. but the problem is that i want to import this addresses (d:\temp....) from a ListBox ! but an error happens! it says it can not convert string to object! let me show you what i wrote:
for(int i=0;i<listbox.lenght;i++){
file.delete(listbox.items[i]);
}
in the listbox i stored the path of the files that should be deleted. but i can not delete them with this code.

I suspect your error message is the other way round:
"Cannot implicitly convert type 'object' to 'string'. An explicit conversion exists (are you missing a cast?)"
Try:
File.Delete((string) myListBox.Items[i]);
You also might want to consider using a foreach instead of the for:
foreach (object o in myListBox.Items)
{
File.Delete((string) o);
}
It is a bit cleaner to read if you aren't using the loop variable for anything else.
