序列化分块文件

Question

I was following the example found here on serializing chunks of a large file. Somehow being new to serialization I am now lost as to what parameters to pass to my Serialize method. I have shelved the approach I was using yesterday because of the OOM exception. Will appreciate your help.

Public Shared Sub ReadAndProcessLargeFile(theFilename As String, ByVal obj As LocalDBObject, Optional whereToStartReading As Long = 0)
Dim bf As New BinaryFormatter() ' Create a binary formatter for this stream.

Using fileStram As New FileStream(theFilename, FileMode.Open, FileAccess.Read)
    Dim buffer As Byte() = New Byte(fileStram.Length - 1) {}
    fileStram.Seek(whereToStartReading, SeekOrigin.Begin)
    Dim bytesRead As Integer = fileStram.Read(buffer, 0, buffer.Length)
    While bytesRead > 0
        bytesRead = fileStram.Read(buffer, 0, buffer.Length - 1)
        'It is here where I am now lost. What parameters do I supply to my Serialize method below 
        bf.Serialize()
    End While
End Using
End Sub

Hmmm, that code is just not serializing anything, to serialize you should do this:

Public Shared Sub Serialize(theFilename As String, ByVal obj As LocalDBObject)
    Dim bf As New BinaryFormatter() ' Create a binary formatter for this stream.

    Using fileStram As File.Create(theFilename)
        bf.Serialize(fileStram, obj);
    End Using
End Sub

But I suspect this is not what you want, unless you explain a bit better your question is really hard to understand what you want to achieve.
