Convert byte array to a single 2

[llmclaughlin]

I'm getting bytes from a device which is in a reverse order, I need to reverse the bytes and convert that from a byte array to a single datatype.

This will give me the reverse of the byte order

Dim ucConversion(3) as byte
Dim ucNodePacket(26) as byte

For i = 0 to 3
ucConversion(i) = ucNodePacket(13 - i)
next

Now I need to convert the ucConversion(bytearray) to a single data type, this is where I need help.

Thanks

Take a look at the BitConverter class.

Here is some sample code that may help

Option Strict Off
Option Explicit On

Imports System.IO
Imports System.Text
Imports System.Buffer

Dim bDesc(), bPtid(), bData() As Byte
Dim dNo, dEa, dEl As Double
Dim sXval As Single

......Open binary file with BinaryReader - call it BR

bData = BR.ReadBytes(80) 'Read 80 bytes into byte array with BinaryReader

sXval = BitConverter.ToSingle(bData, 5) 'Starting at and including byte 5 read & cvt to single
dNo = BitConverter.ToDouble(bData, 48) 'Starting at and including byte 48 read & cvt to double
dEa = BitConverter.ToDouble(bData, 56)
dEl = BitConverter.ToDouble(bData, 64)
