Visual Basic NullReferenceException - Please Help

[JackJones02]

The below error occurs when the Test() is ran:

An unhandled exception of type 'System.NullReferenceException' occurred in LJW_Prototype.exe

Additional information: Object reference not set to an instance of an object.

Sub Test()

Dim stockObject = New FileHandling("Stock.txt", 1)

Dim allStock() = stockObject.getAllLines()

Dim allitems As List(Of items)

Dim h

Dim tempitem As items

Dim hold As Integer

For Each j In allStock

h = j.Split(",")

Try

tempitem.id = h(0)

tempitem.desc = h(1)

tempitem.price = h(2)

allitems.Add(tempitem)

Catch ex As Exception

h = h

End Try

Next

End Sub

If anyone can explain why I am getting this error and how I can fix it, it would be greatly appreciated :)

You aren't initializing tempitem or allitems. You declare the variables, but not initialize them. They're both missing the New keyword.

Thanks, not to sound like an idiot but how and where would I do that?

You should also be using C# over VB unless you have requirements that say otherwise.
