Writing an Array to a text file

Question

I’m very new to programming so this is probably fairly easy. And forgive me if I'm asking this in the wrong section. Point me to the right one and I will go  there.

I am writing a program that will read a text file of results (all numbers) to an array and then perform various mathematical analysis of those numbers. Unfortunately the results text file has random blank spaces that mess up the array. I have managed to set up a routine to remove the blank spaces. How can I write the new results array to a new text file?

Here is my code so far.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Readfile.Click

'Read the file

Dim res1Array As New ArrayList

Dim fileReader As System.IO.StreamReader

fileReader = My.Computer.FileSystem.OpenTextFileReader("C:\resultol.txt")

While Not fileReader.EndOfStream

res1Array.Add(fileReader.ReadLine)

End While

 ' remove blanks

Dim a1 As Integer

For a1 = 0 To res1Array.Count

res1Array.Remove("")

Next a1

 

End Sub

 

What I would like to do now is write the contents of resArray1 to a file at c:\working.txt

Any help would be appreciated..

Answer 1

simply go through each item in the array and write it to the file:

 

Dim theWriter as new StreamWriter("fileName.txt")

for each currentItem as String in res1Array

   theStreamWriter.WriteLine(currentItem)

next

theWriter.Close()

Thanks so much for your help. I will try this out. Will the code work for VB express as well? For that matter is their a  lot of diffrence between standard VB and VB express?
