[RESOLVED] A couple of questions about structures

[cicatrix]

Hi, I have this structure:

<StructLayout(LayoutKind.Sequential)>
Public Structure ContFileHeader
    Public MagicID As UInteger    ' 4 bytes
    Public MajorVer As Byte       ' 1 byte
    Public MinorVer As Byte       ' 1 byte
    Public Reserved1 As UInt64    ' 8 bytes
    Public Reserved2 As UInt64    ' 8 bytes
    Public FTType As Byte         ' 1 byte
End Structure

4 + 1 + 1 + 8 + 8 +1 = 23 bytes

Why then:

Dim header As New ContFileHeader
Debug.WriteLine(Marshal.SizeOf(ContFileHeader))

gives me 32 ?

Is there a way go get 23 as the size of this structure?
