Question

I have asked this type of a question before but this one IS different. I need to find the root folder of a folder.

For example:

I get is

C:\Program Files (x86)\EdisonFactory\NetOffice
C:\Program Files (x86)\EdisonFactory\NetOffice
C:\Program Files (x86)\EdisonFactory\NetOffice
C:\Program Files (x86)\EdisonFactory\NetOffice
C:\Program Files (x86)\EdisonFactory\NetOffice\Plugins
C:\Program Files (x86)\EdisonFactory\NetOffice\Plugins
C:\Program Files (x86)\EdisonFactory\NetOffice\Plugins

I used this code before:

DsVersions.ASSEMBLY2Row row = dsVersions.ASSEMBLY2.NewASSEMBLY2Row();
row.FOLDER = Path.GetDirectoryName(fileName);

And then i found this code and thought it was the answer:

DsVersions.ASSEMBLY2Row row = dsVersions.ASSEMBLY2.NewASSEMBLY2Row();
DirectoryInfo directoryName = new DirectoryInfo(Path.GetDirectoryName(fileName));
row.FOLDER = directoryName.Name;

After this code i was getting this:

NetOffice
NetOffice
NetOffice
NetOffice
Plugins
Plugins
Plugins

It’s close but again all i need is Plugins. I have tried doing Path and File but it won’t work, I always get an error.

Answer 1

            string rootDir = folderBrowserDialog.SelectedPath;
            string fileDir = Path.GetDirectoryName(fileName);
            if (rootDir.Length < fileDir.Length)
                row.FOLDER = fileDir.Substring(rootDir.Length + 1);

That did the trick.
