Hello everyone

I'm fairly new to Visual Basic, so this question might be very "dumb" .
For an assignment I have to use a class that contains a number of properties, among other things, to remember the maximum length of the various data (maximum length of the name, maximum length of the country, etc.) for the purpose of aligning the data.

I've tried a few things but I'm not sure how to do about this.

Can you guide me in the right direction?

Form 1:

 Dim NameLength As New LayoutClass

If Persons Is Nothing Then

   TextBox1.Text = "no person was found"
            Dim queryData = From Person In Persons.Descendants("Person")
                Where (Person.Attribute("Name")).Value <> ""
              Select Naam = Person.Attribute("Name").Value,
              Country= Person.Attribute("Country").Value
              Order By (Name)

TextBox1.Text = " "
TextBox1.Text = "The persons are: " & vbCrLf & NameLength.PersonNameLength


Public Class LayoutClass

    Public Property NameLength() As Short
    Public Property CountryLength() As Short

    Public Function PersonNameLength() As Short
        Dim PersonLength As Short
        If PersonLength > NameLength Then
            PersonNameLength = PersonLength 
        End If

        Return PersonNameLength 

    End Function
End Class

Thanks for the effort!
