VB.net Serialization Issue

Question

I'm trying to save the following class to the user.config and I'm not sure what I'm doing wrong. Is the dictionary object not allowing the class to be serialized?

<Serializable()>Public Class RunInformation
    Public ExecutablePath As String
    <NonSerialized()> Public Settings As Dictionary(Of String, String)
    <NonSerialized()> Public ProcessId As Integer
    <NonSerialized()> Public Handle As IntPtr
    <NonSerialized()> Public TabPageHandle As IntPtr

    Public Sub New()
        ExecutablePath = ""
        Settings =  New Dictionary(Of String, String)
    End Sub
End Class

Saving:

Private Sub Form1_Closing(sender As Object, e As EventArgs) Handles MyBase.Closing
    my.Settings.Setting = New RunInformation()
    My.Settings.Save()
End Sub

XML File:

<userSettings>
    <BotManager.My.MySettings>
        <setting name="Setting" serializeAs="Xml">
            <value />
        </setting>
    </BotManager.My.MySettings>
</userSettings>

When you open the Settings UI editor there is no Dictionary listed because standard XML serializers dont work with them. — Ňɏssa Pøngjǣrdenlarp, Jul 27 '16 at 16:27
I have the setting configured as so: http://imgur.com/a/0PRco — chancity, Jul 27 '16 at 16:27
Still, `RunInformation.Settings` is not XML serializable because it is a `Dictionary` — Ňɏssa Pøngjǣrdenlarp, Jul 27 '16 at 16:31
I know that dictionaries don't implement ISerialization interface. I was hoping marking that property NonSerialized would be a fix. Is this not the case? — chancity, Jul 27 '16 at 16:32
It looks like the only thing you want to save is `ExecutablePath`? if so, why not just save that as a string setting? — Ňɏssa Pøngjǣrdenlarp, Jul 27 '16 at 16:34
I'm actually trying to save a list of RunInformation and I may add more properties to RunInformation in the future. `Public Class Bots Public Items As New List(Of RunInformation) Public Sub New() End Sub End Class` — chancity, Jul 27 '16 at 16:39

The problem is that your serializing the info as XML but using the binary serialization control attributes.

Use the attribute System.Xml.Serialization.XmlIgnore instead
