Simon,
1) .NET Framework has two classes that you can use to obtain the
information specific to files and directories. They are: FileInfo and
DirectoryInfo. Unfortunately, there is not a method on the
DirectoryInfo class to return the size of the Directory. I wrote a
little helper class that has a method on it that will return the size
of the directory in bytes. Here it is:
public class FileSystemHelper
{
private FileSystemHelper()
{
}
// returns the size of the given directory in bytes.
public static long GetDirectorySize(DirectoryInfo di)
{
if(di==null)
{
throw new ArgumentNullException("di");
}
long size = 0;
FileInfo[] files = di.GetFiles();
// sum up file size
if(files!=null && files.Length>0)
{
foreach(FileInfo fi in files)
{
size+=fi.Length;
}
}
// sum up dir size
DirectoryInfo[] dirs = di.GetDirectories();
if(dirs!=null && dirs.Length>0)
{
foreach(DirectoryInfo dii in dirs)
{
// recursive call
size+=FileSystemHelper.GetDirectorySize(dii);
}
}
return size;
}
}
You can get to the contents of the directory by calling GetFiles() and
GetDirectories().
2) GetFiles() and GetDirectories() is overloaded to accept a
searchPattern so you can use that to exclude certain
files/directories.
3) I don't know of any open source tools that do this kind of stuff.

Hi all,
I am looking to make an open source Drive space viewer. One that displays
the sizes in a graph and lets you move through the directories via a
treeview at the left.
I have three questions i hope someone could help with:
1. The problem I have is tallying up the directories and sub
directories. This is made even more complicated by the fact that I need to
allow the user to exclude certain sub directories when doing the
calculations. Does anyone know if there is a class in the framework that, at
the very least, can tell me the size of a folder and its contents.
2. Does anyone have any code or suggestions about how I could handle the
problem of excluding various directories. The user needs to click a tick box
in the treeview to have that dir included
3. Does anyone know of an open source application that I could look at for
this purpose
Thank you everyone
Simon
