Having a problem with reading a binary file

[MrPolite]

I dont know why I get this error. I simply want to read every byte of a binary file. I just declared a BinaryReader variable:

Dim strmSrc As FileStream = New IO.FileStream("c:\a.exe", FileMode.Open)
        Dim brSrc As New BinaryReader(strmSrc)
 
     [color=red]   Do While brSrc.PeekChar <> -1[/color]
            brSrc.ReadByte()
        Loop

if the file is small it works fine (like 10 KB) but when I test it with bigger files (200KB) it gives me this error:
An unhandled exception of type 'System.ArgumentException' occurred in mscorlib.dll

Additional information: Conversion buffer overflow.

and the error happens on the red line, because of brSrc.PeekChar call. I don't understand why calling that could cause a problem. What am I doing wrong? I just want to read all the bytes in the file (this is just a sample code of course )

Try changing <> - 1, to Do While brSrch.Peek >-1......
Does it behave the same way???

Failing that... look at the example MS code for reading.writing large files... OR, perhaps you're not Flushing the file stream before you close it (i know it should do that automatically, but just to eliminate the possiblity, put it in)... and make sure to seek the filestream to origin.
