InvalidCastException when trying to stream a byte array, I think...

[lamiumthetanker]

Hi guys, really stuck here, to be honest, I'm not really sure where I'm going wrong here. What I'm trying to do is to stream a PDF document to a browser by clicking a button. Below is a snippet of the code that I am using.

I am reading the pdf correctly but for some reason it keeps thinking that my Byte is an Integer and keeps throwing an InvalidCastExce ption Error

Here is the code snippet:

Const ChunkSize As Integer = 1024
Dim buffer() As Byte = New Byte(ChunkSize) {}
Dim binary(reader("document")) As Byte *** Exception is thrown here***
Dim ms As New MemoryStream(binary)
Dim SizeToWrite As Integer = ChunkSize

Here is the error:

Server Error in '/' Application.
Conversion from type 'Byte()' to type 'Integer' is not valid.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
