vb.net Is there a limit to the number of objects you can create?

Question

I'm trying to find the limit, if there is one, of the number of objects you can create.

Logically there is a limit and this limit would be that of the capacity of the RAM but to test concretely I established this piece of code and I let it run

Module Module1
    Sub Main()
        Dim newObj As New classTest.classTest
        Dim i As Int64
        Dim MAX As Int64
        MAX = 9223372036854775807 ' max 64 bits int
        For i = 1 To MAX
            newObj = New classTest.classTest
            Console.WriteLine(i)
        Next
        Console.ReadLine()
    End Sub
End Module

I let this code run for a while and it didn't crash, so I thought of a possible limitation like :

• RAM Amount
• OS Architecture (32/64bits)
• Memory Swap on/off

But these are just guesses, my teacher wants the limit and proof of it, can someone help me or direct me please?

Answer 1

Try keeping all the objects you create. Replace your code with this

    Dim newObj As classTest.classTest
    Dim newObjCollection As New List(Of classTest.classTest)
    Dim i As Int64
    Dim MAX As Int64 = Int64.MaxValue
    For i = 1L To MAX
        newObj = New classTest.classTest
        newObjCollection.Add(newObj)
        Console.WriteLine(i)
    Next
    Console.ReadLine()

I suspect you'll crash with out of memory.
