Can I have a property that contained an array?

For instance, if I have Group
consisting of Person1, Person2, etc.

Could I have

Public Property Group() as Array
Get
  Return myGroup
End Get
Set (ByVal Value As Array)
  myGroup=Value
End Set
End Property

If you're using VB2005, use System.Collections.Generic.List(of Person)

This is essentially a typesafe array.

Public Property People() As List(of Person)
Get
  Return myGroup
End Get
Set (ByVal Value As List(of person))
  myGroup=Value
End Set
End Property

In any case, you can create properties for any type of object, including array, hashtable, string, integer, object, stringbuilder, and anything else you can think of.

Hi sirbounty;

In answer to your question, Yes. It can be of any type as well as arrays. The sample code below will show how to implement it.

' Person class
Public Class Person
    Public FirstName As String
    Public LastName As String
End Class

' Class1 stores Person array
Public Class Class1

    Dim myGroup(2) As Person

    Public Property Group() As Person()
        Get
            Return myGroup
        End Get
        Set(ByVal Value As Person())
            myGroup = Value
        End Set
    End Property

End Class


'Code in main which creates a Class1 and Person array to be stored
        Dim mc As New Class1
        Dim pArray(2) As Person
        Dim p As Person
        p = New Person
        p.FirstName = "John"
        p.LastName = "Doe"
        pArray(0) = p
        p = New Person
        p.FirstName = "Tom"
        p.LastName = "Smith"
        pArray(1) = p
        mc.Group = pArray
        p = New Person
        p.FirstName = "Fernando"
        p.LastName = "Soto"
        pArray(2) = p
        mc.Group = pArray

        ' Get the array and print it out
        For Each p In mc.Group
            Console.WriteLine("First Name: " & p.FirstName & " " & _
                "Last Name: " & p.LastName)
        Next


Hope that this was of some help.

Fernando

For this one - I'm going to have to use 2003...
A bit beyond me though, I'm afraid...
Thanx.
