How do I Read/Write a structure to a binary file?

[Tln1]

Ok, It is apparent that FileGet/FilePut are just in VB.NET for compatibility.
Unless you are accessing very small files these functions are useless. So
if you guys are not using the BinaryReader/Writer you will be very disappointed
with file access speeds - got that off my chest.

After playing around with BinaryReader/Writer for several hours, it is definitely
the tool to use for speedy file access but I have hit yet another problem
reading/writing binary files. How do I write or read a structure like this

Public Structure COGO_PT
Dim ID As Byte
Dim PT As Short
<VBFixedArray(20)> Dim DESC() As Byte
Dim NO As Double
Dim EA As Double
Dim EL As Double
End Structure

This has me stumped, any of you have a suggestion or resource?

Did you try FileGetObject and FilePutObject?

more on this. I'm finding that fileputobject works find, but =
filegetobject is very slow (5-10 seconds) with large arrays (e.g. 35 x =
1000).
