Topic: StreamReader

[djee]

I'm a newby to VB.NET... I need to create a StreamReader SUB that would open a text file containing the following structure;

Code: [Select]

Projectname , TemplatePath , Plotstylepath
Projectname , TemplatePath , Plotstylepath
Projectname , TemplatePath , PlotstylepathI need to populate a LISTBOX containing only the Projectname variable... I'm having some difficulty with this one...
Any suggestion would be greatly appreciated...

Open file with StreamReader

• Do a while loop checking StreamReader.EndOfStream
• Call StreamReader.ReadLine in while loop.
  
• Call String.Split with ',' as a delimiter on value returned from ReadLine
  
• Get first value from array returned from Split

Code - Visual Basic: [Select]

1. Imports System.IO
2.  
3. Module Module1
4.  
5.     Sub Main()
6.         ReadCSV("C:\temp\New Text Document.txt")
7.         Console.Read()
8.  
9.     End Sub
10.     Public Sub ReadCSV(strFileName As String)
11.  
12.         Dim sr As New StreamReader(strFileName)
13.  
14.  
15.         Dim strline As String = ""
16.  
17.         Dim vals As String() = Nothing
18.  
19.         While Not sr.EndOfStream
20.  
21.             strline = sr.ReadLine()
22.  
23.             vals = strline.Split(",")
24.  
25.             Console.WriteLine(vals(0))
26.         End While
27.  
28.     End Sub
29. End Module
