Module Module1

Public Structure student
Dim name As String
Dim marks() As Integer
End Structure

Sub Main()

Dim ocra(2) As student
ReDim ocra(2).marks(2)

ocra(0).marks(0) = 52

Console.WriteLine(ocra(0).marks(0))
Console.ReadLine()

End Sub

End Module

--> When I run this code, I keep getting this error:
Object reference not set to an instance of an object.

Can someone help me with this?

Solution 1

I think:
When you execute the command

VB

ReDim ocra(2).marks(2)

you only declare the size of ocra(2).marks() to be 2. With ocra(0).marks(), you did not declare!
You replace

VB

ReDim ocra(2).marks(2)

by

VB

ReDim ocra(0).marks(2)

Have a good luck! (I'm not supporter in VB.NET).
