[RESOLVED] Object reference not set to an instance of an object.

This is probably something really simple that I'm just over looking but when I run my code I get that error.

My code is this:

Code:

---

Imports System.IO

Partial Class _Default
    Inherits System.Web.UI.Page
    Dim news() As String
    Dim newsID() As String
    Dim newsTitle() As String
    Dim newsBody() As String
    Dim newsAuthor() As String
    Dim i As Integer = 0


    Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
        LoadData()
        WriteData()
    End Sub

    Private Sub LoadData()
        Dim newsFile As String = Server.MapPath("~/App_Data/news.txt") 'set where the data is stored


        Dim srdData As System.IO.StreamReader
        srdData = New IO.StreamReader(newsFile)

        Dim strLine As String

        Do Until srdData.Peek = -1
            strLine = srdData.ReadLine
            news = strLine.Split(";")

            newsID(i) = news(0)
            newsTitle(i) = news(1)
            newsBody(i) = news(2)
            newsAuthor(i) = news(3)
            i += 1
        Loop
        srdData.Close()

    End Sub

---

The content of the text file is like this:

newsid;title;content;author

The error occurs on the bolded line. When I look through it by debugging I see that the value of i in newsID(i) = 0 as it should and also news(0) = 1 which is what is in the text file so that's correct. So I really don't understand why I'm getting this error :sick:

Thanks,

You're declaring a bunch of array variables at the top of your page but you never actually create any arrays. To create an array you have to specify the size. As you don't know what size the array has to be you shouldn't be using arrays at all. This is exactly what collections are for. You should be using List(Of String), not String().

Ah ok, problem solved.

Thanks for the help!
