VB.Net example using System.IO and how to process all files (txt) on a drive Mountain Computers MTNCOMP GGPCTU 775-287-9552

Just looking for an example for a tool I am writing. This gets me close. I changed a little bit of it so it can run in parallelism. This actually works. in your code, just call RecursiveSearch(). This is an excerpt from a console app, so you can comment / rem out the console.readkey() near the bottom.

Imports System.IO



		  Sub RecursiveSearch()

		    Dim searcher As New Task(Of IList(Of String))(Function()

		                                                    Return GetFiles("C:\", "*.txt")

		                                                  End Function)

		    searcher.Start()

		    Console.WriteLine("Searching for .txt files in C:\ and all subdirectories...")

		    searcher.Wait()

		    Dim files = searcher.Result

		    Console.WriteLine(String.Format("{0:N0} .txt files found.", files.Count))

		    Console.ReadKey()

		  End Sub



		  Function GetFiles(directoryPath As String, filter As String) As IList(Of String)

		    Dim files As New List(Of String)

		    Dim directories() As String = Nothing

		    Try

		      files.AddRange(Directory.GetFiles(directoryPath, filter))

		      directories = Directory.GetDirectories(directoryPath)

		    Catch ex As Exception

		      Console.WriteLine($"Error while processing folder {directoryPath}.")

		    End Try

		    If directories IsNot Nothing Then

		      For Each directory In directories

		        files.AddRange(GetFiles(directory, filter))

		      Next

		    End If

		    Return files

		  End Function
