Filter file names on their names or attributes

Filter file names on their names or attributes

The GetFiles and GetDirectories methods of the System.IO.Directory class can take an argument containing wildcards, to filter the result:

' Display all the *.txt files in C:DOCS.Dim fname As StringFor Each fname In Directory.GetFiles("c:docs", "*.txt")    Console.WriteLine(fname)Next

You can use the GetCreationTime, GetLastAccessTime, GetLastWriteTime and GetAttributes shared methods to display information about a file or a directory, or to filter files according to their attributes:

For Each fname In Directory.GetFiles("c:docs", "*.txt")    ' Display only read-only files.    ' (You need CBool if Option Strict is on.)    If CBool(File.GetAttributes(fname) And FileAttributes.ReadOnly) Then        Console.WriteLine(fname)    End IfNext
