File-Search-Routine in VB.Net

Last Modified: 2012-06-21
Hi Experts,

I've wrote a File-Search-Routine in VB.Net (see Code-Example).

If my EXE search above a whole Volume (i.e. C:\) a exception will be cause by searching in i.e. SYSTEM VOLUME INFORMATION "access is denied".

How can I foreclose these special Directories in my Code?


Function SearchNonSQLFiles(...

        Dim Dir As New DirectoryInfo(StartDir)
        For Each fi As FileInfo In Dir.GetFiles
            If (StrComp(Path.GetExtension( ...
                Catch ex As Exception
                End Try

            End If

        For Each subdir As DirectoryInfo In Dir.GetDirectories
            ergebnis = SearchNonSQLFiles(...
        Return ergebnis
End Function
