The size of the bytearray received to the client is different from that sent from the WCF service

[spider58]

I have a Self Hosted WCF service which is reading a big RAR file with binaryreader and returning bytearray to client

Service splitting file as parts and 10MB per parts( 10485860 Bytes)

I checking on debug mode for size of bytearray in WCF service before return and seeing 10485860 Bytes. So this is true size.


But client received 13981237 Bytes per parts, why is this difference.

This making my file is corrupt when i create clientside file with received bytes

This is my code from WCF

Dim i As Integer = 0


my_InStream = New System.IO.FileStream("d:\temp\" + File, FileMode.Open, FileAccess.Read, FileShare.Read)
Dim my_ibinaryreader As System.IO.BinaryReader = New System.IO.BinaryReader(my_InStream)
Dim my_splitArr As New ArrayList

'Dim ofile As FileInfo = New FileInfo(File)

Dim ofilesize As Long = my_ibinaryreader.BaseStream.Length

Dim partcount As Integer = ofilesize \ 10485860

If ofilesize Mod 10485860 <> 0 Then partcount += 1


my_ibinaryreader.BaseStream.Position = currentPartNumber * 10485860
Dim myblocksize As Long = 0
Dim my_bytearray() As Byte

If currentPartNumber = partcount - 1 Then
myblocksize = ofilesize - (currentPartNumber * 10485860)
Else
myblocksize = 10485860
End If

my_bytearray = my_ibinaryreader.ReadBytes(myblocksize)
my_ibinaryreader.Close()
my_InStream.Close()
Return my_bytearray



and This is my client code



dim myReceivedByteArray as byte()

dim partCount as integer = FileSize \ 104857600

if FileSize mod 104857600 <> 0 then partCount += 1

dim myWebClient as new WebClient

for i as integer = 0 to partCount -1
myReceivedByteArray = myWebClient.DownloadData(string.format("SERVICEURL?file=bla.rar&currentPartNumber={0}",i))
