VB.Net Data Class

I am looking for some help using a Data Class more effectively. I have multiple classes for example Students

Public Class Student
        Public Property StudentID() As Integer
            Get
                Return m_StudentID
            End Get
            Set
                m_StudentID = Value
            End Set
        End Property
        Private m_StudentID As Integer
        Public Property StudentName() As String
            Get
                Return m_StudentName
            End Get
            Set
                m_StudentName = Value
            End Set
        End Property
        Private m_StudentName As String
        Public Property StudentClass() As String
            Get
                Return m_StudentClass
            End Get
            Set
                m_StudentClass = Value
            End Set
        End Property
        Private m_StudentClass As String

        Public Property UniqueId() As String
            Get
                Return m_guid
            End Get
            Set
                m_guid = Value
            End Set
        End Property
        Private m_guid As String
    End Class

Select allOpen in new window

Now i set the values like this

 Dim myData As New Nodes.Student

        myData.StudentName = "Tom Smith"
        myData.StudentID = "1234567890"
        myData.StudentClass = "VB.NET"

Select allOpen in new window

So here is what i am trying to do  can i get easily all data fields in mydata ? how idealy i would like to loop thru all and only use the ones with data . I want to use only propertys where the value <>"" and then create a string like

"property: 'Value', property: 'value'"
