[RESOLVED] [2005] toString() equiv for an object in VB.net

Hi there,

I have the following class

Code:

---

Public Class Server
    Private _realmname As String
    Private _isEU As Boolean
    Private _isUS As Boolean
    Private _isUp As Boolean
    Private _type As String
    Private _population As String

    ' Method to set/get the realm name, eg Stormrage
    Public Property RealmName()
        Get
            Return _realmname
        End Get
        Set(ByVal value)
            _realmname = value
        End Set
    End Property

    ' Method to set/get whether the realm is hosted in Europe
    Public Property isEU()
        Get
            Return _isEU
        End Get
        Set(ByVal value)
            _isEU = value
            _isUS = Not value
        End Set
    End Property

    ' Method to set/get whether the realm is hosted in the US
    Public Property isUp()
        Get
            Return _isUp
        End Get
        Set(ByVal value)
            _isUp = value
        End Set
    End Property

    ' Method to set/get what kind of realm this is, eg PvP, RP, Normal, RPPVP
    Public Property Type()
        Get
            Return _type
        End Get
        Set(ByVal value)
            _type = value
        End Set
    End Property

    ' Method to set/get the population load on the server, eg New, Full, Medium
    Public Property Population()
        Get
            Return _population
        End Get
        Set(ByVal value)
            _population = value
        End Set
    End Property
End Class

When I add instances of this class to a ListBox, I'd like the ListBox to print the "_realmname" attribute, sort of like the way you have the toString() function for Java (iirc).
Example, I have a listbox named ListBox_AllServers, now when I add a Server instance with _realmname set to "Stormrage", I'd like the following code

Code:

---

Dim StormrageServerObj as Server
StormrageServerObj.RealmName = "Stormrage"
ListBox_AllServers.Items.Add(StormrageServerObj)

---

To result in the name "Stormrage" appearing in the listbox.

What function do I need to implement in my Server class to make this happen?

Thanks in advance.

Just like in Java. Override the ToString method in your object and make it return whatever you want.

vb.net Code:

Public Overrides Function ToString() As String
    Return _realmname
End Function

Heh, too obivous :P Thanks it works a treat now!

Code:

---

    Public Overrides Function ToString() As String
        Return _realmname
    End Function

That seems correct, right?

If that is the value that you want to return, then yes.

Just a side note, why are you not declaring your property types? For instance if RealmName is always going to be a string, why not declare it as such?

Thanks peeps! Seems next time I should hit refresh a few more times before posting a final post! It seems whenever I think something is going to be complicated in VB.net, the forums prove me wrong!

A small oversight. Thanks for pointing it out. I will amend my code.
