.Net Framework 1.1 - listing directories containing full stop (period)

[stainless]

Given I have a folder root called C:\Users\, I want to get a list of
all the sub-folders directly under this C:\Users| folder that contain
a full stop (.), but only at the first sub-folder level.

Using the example folder structures below:

C:\Users\philip.marlowe\monkeynuts
C:\Users\philip.marlowe\zebra.stripes
C:\Users\Jethro\popular.front
C:\Users\john.smith\monkeynuts
C:\Users\john.smith\cabbage
C:\Users\boris.johnson\
C:\Users\femor
C:\Users\full.stops.found

My search should retrieve:

C:\Users\philip.marlowe\
C:\Users\john.smith\
C:\Users\boris.johnson\
C:\Users\full.stops.found

This is only the sub-folders immediately below C:\Users\ that contain
the full stop

I am struggling with the code for this even though I know it should be
simple. Any help appreciated.

Cheers

Mark

The File and Directory Classes have a overload that can be very
usefull that accepts file/directory filtering. For example:

string[] subDirs = System.IO.Directory.GetDirectories(@"C:\Users\",
"*.*");

 

[stainless]

string[] subDirs = System.IO.Directory.GetDirectories(@"C:\Users\",
"*.*");

I did try that but "*.*" returns every sub directory. I think the
issue is something to do with the "." itself. It looks like this acts
as a special "select all" value (I found some info on the web
regarding DOT being a special metacharacter). I may not have fully
understood how it is being treated but it is certainly retrieving
every folder name

I'm sure there are better solutions but this works...

string dirPath = @"c:\users";
string[] dirs = Directory.GetDirectories(dirPath);
foreach (string d in dirs)
{
if (d.IndexOf('.') > -1)
{
// do something with the directory...
Debug.WriteLine(d);
}
}

Right, didnt test he code. My bad. Anders code will do the trick.

I'm sure there are better solutions but this works...

string dirPath = @"c:\users";
string[] dirs = Directory.GetDirectories(dirPath);
foreach (string d in dirs)
{
if (d.IndexOf('.') > -1)
{
// do something with the directory...
Debug.WriteLine(d);
}
}

A LINQ version would be :

string dirPath = @"C:\users";
IList<string> dirs = (from dir in Directory.GetDirectories(dirPath)
where dir.Contains(".")
select dir).ToList();

But .NET 1.1 does not have LINQ.
