new class with inherits, some properties gone?!

Code:

---


Public Class Form1

    Public Class SearchTask
        Inherits List(Of String)
        ' Fields
        Public SearchTerm As String
        Public SoundEx As String
        Public AdminSettingsHash As Integer

    End Class

    Public St As New SearchTask

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        St.AdminSettingsHash = 302
        St.Add("test1")
        St.Add("test2")
        St.Add("test3")
        St.Add("test4")
        St.Add("test5")
        MsgBox(St.AdminSettingsHash)
    End Sub

End Class

---

Why is it that if you run this, a message box appears stating '302', but if you check the debugger for the 'St' no property called 'AdminSettingsHash' is listed. Also if you serialize the class, the list of strings are saved, but not the SearchTerm, SoundEx or AdminsettingsHash.

Thanks in advance!

The class isn't marked serializable, so that could have an issue, depending on what type of serialization you are using. There are plenty of properties that don't show up in the debugger. I'm pretty sure that you can set them that way (I think I did, once), but in your case, it appears that not showing up is all they are doing, since you report that the code is working (other than the serialization). You don't have them as properties anyways. They are member variables as you have it written.

What do you mean by "check the debugger"? That could mean a couple different things, and the specific one you are using may be important.

To make it more clear;

Code:

---

Imports System.IO
Imports System.Xml.Serialization


Public Class Form1

    Public Class SearchTask
        Inherits List(Of String)
        ' Fields
        Public SearchTerm As String
        Public SoundEx As String
        Public AdminSettingsHash As Integer

    End Class

    Public St As New SearchTask

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        St.AdminSettingsHash = 302
        St.SoundEx = "0123"
        St.SearchTerm = "yadda"
        St.Add("test1")
        St.Add("test2")
        St.Add("test3")

        Dim string_writer As New StringWriter()
        Dim serializer As New XmlSerializer(GetType(SearchTask))
        serializer.Serialize(string_writer, St)
        MsgBox(string_writer.ToString)

    End Sub

End Class

Why don't I see 'AdminSettingsHash' etc, in the XML string?

If I remove the 'inherits' from the class, the other options do show up.

Of course I could 'code around it' somehow, but I've rather understand why this is happening. Also, when I debug, I don't see 'adminsettingshash' with the 'st' instance.

You can give the fields an System.ComponentModel.EditorBrowsable attribute to make them show up in Visual Studio Intellisense:

Code:

---

        <System.ComponentModel.EditorBrowsable(EditorBrowsableState.Always)> _
 Public TestField As Object

---

The EditorBrowsableState argument determines if the field or property will show up in the Intellisense Common tab or Advanced tab. It wouldn't surprise me if something similar applies to using the Serializable attribute, but I don't have much experience with that. BB
