How do I make this work in vb.net?

I am trying to read/write a simple text file in net 2008 but can't, as yet, get it to work.
Any help would be appreciated.
This is how I use to do it in VB6

Code:

---

MyStr = App.Path & "\Data\Data.txt"

Open MtyStr For Input As #1
Do While Not EOF(1)
Input #1, Num(a, 0), Num(a, 1), Num(a, 2), Num(a, 3), Num(a, 4), Num(a, 5), Num(a, 6)

 a = a + 1
 
Loop
Close #1

---

Look up the StreamReader() and StreamWriter() classes. That's the way to access files in VB.Net

Try these samples, also: http://code.msdn.microsoft.com/vbsamples/

I found info about the streamreader/writer in my book and got it to work, the problem is that it reads/ writes the whole thing, I was looking for a way to read data individually separated by commas. Would you know of a simple way to do this?

The best way or at least a way I often use is to read the entire file and then use the split method to place it into an array. This works very well and is very fast.

And there's me thinking it was going to be so easy.

Just need to find something helpful on splitting now.:sick:

It is actually very easy.

Use the streamreader to read either a line or the entire file into a string variable.

Dim an array and use the split function on your previous variable to break it down into each element.

Code:

---

Dim MyFile as new System.IO.StreamReader("\MyFile.Txt")
Dim FileContent as string=MyFile.ReadToEnd()
MyFile.Close
Dim FileFields as string()=FileContent.Split(",")

Cool, thank you.
This is my code so far and it seems to be working very well except for the splitting bit.

Code:

---

a = 0
        Dim objfile As New System.IO.StreamReader("c:\data.txt")
        Nationaldate = objfile.ReadLine()
                Do Until Nationaldate Is Nothing
                           
 ListNational.Items.Add(Nationaldate)
 Nationaldate = objfile.ReadLine()
            a = a + 1
        Loop
        objfile.Close()
        objfile.Dispose()
Label1.text= "Line Count = " & a+1

---

It loads in over 1000 lines, each line has 7 data entries.
How would I insert the split command to read the 7 separate data entries into a array at each loop?

Split Nationaldate from inside the loop, and load the array (based on the value of a)

(a,0),(a,1),(a,3)

The examples I have are a little unclear as to the wording or layout I would use to split it into a array (a, 0 ) through to (a,6) and my first few attempts have failed.

I hope it helps a bit.

Yeehee!! I have done it, and it works like a charm :)

Thank you so much for all of you who took time to help, it is very much appreciated.

Now that I have learned to load and save I can move on to other heroic tasks.:D
