vb.net saving arrays

hi

im trying to save a class with initial sizes

Code:

---

    Public Sub SaveMap(ByVal aMap As map, ByVal fileName As String)

        Dim ser As New XmlSerializer(GetType(map))
        Dim fs As New FileStream(fileName, FileMode.Create)

        ser.Serialize(fs, aMap)

        fs.Close()
        fs.Dispose()

    End Sub

---

Code:

---

Public Class map

    Public X As Integer = 10
    Public Y As Integer = 10
    'Public Tile(5, 10, 10) As TileRec

    Public test(5, 5) As Integer

    Public Structure TileRec

        Public X As Integer
        Public Y As Integer
        Public Tileset As Integer

    End Structure

End Class

---

actually it won't save the 'test(5,5) as integer'. if i change 'test(5,5) as integer' to test(5) it will save the map well. why wont it save the 'test(5,5)' ?

Multidimensional array serialization is not suported with XML serializers. You can switch to using a binary serialization, but the tradeoffs are these:

1) Binary makes for smaller files, but editing them by hand is nearly impossible.
2) XML serialization makes much larger files that can be readily edited using anything that can read text files.

how will my code look then?

try this:

vb.net Code:

Public Sub SaveMap(ByVal aMap As map, ByVal fileName As String)
 
    Dim formatter As New Runtime.Serialization.Formatters.Binary.BinaryFormatter
    Dim fs As New FileStream(fileName, FileMode.Create)
 
    formatter.Serialize(fs, aMap)
 
    fs.Close()
    fs.Dispose()
 
End Sub

to deserialize:

vb.net Code:

Dim formatter As New Runtime.Serialization.Formatters.Binary.BinaryFormatter
Dim fs As New IO.FileStream(fileName, IO.FileMode.Open)
aMap = DirectCast(formatter.Deserialize(fs), GetType(map))
fs.Close()
