Adding iList element

Question

User31164289 posted

I have this code:

Dim MedicList As IList(Of Medic)

I want to add item in List. When I write this code

MedicList.Add(New Medic)

Visual studio say "MedicList is used before assigned value to it"

How I can do it?

How I can insert properties value for class:

Medic.Name ="Peter"

Medic.Age ="34"

Etc...

Hi,

Have you tried on ArrayList?

        Dim MedicList As New ArrayList
        MedicList.Add(New Medic)

And could you explain a bit more why you cannot use List(T)? It doesn't make sense as iList(T) and List(T) are in the same namespace System.Collections.Generic.
