I wound up doing this:

Dim temp As Byte

Dim hexstring As String

temp = (Convert.ToByte(outputBank(7)) << 7) + _

(Convert.ToByte(outputBank(6)) << 6) + _

(Convert.ToByte(outputBank(5)) << 5) + _

(Convert.ToByte(outputBank(4)) << 4) + _

(Convert.ToByte(outputBank(3)) << 3) + _

(Convert.ToByte(outputBank(2)) << 2) + _

(Convert.ToByte(outputBank(1)) << 1) + _

Convert.ToByte(outputBank(0))

hexstring = Format(temp, "X2")

Which seems to give me what I need. Not sure how (in)efficient it is,

though.

Thanks for the reply.

I first converted the BitArray to an Int32.

Dim result As Int32 = 0

For i As Int32 = 0 To outputBank.Length - 1

If outputBank(i) Then

result += System.Math.Pow(2, i)

End If

Next

MessageBox.Show(result.ToString("X"))

news:Xn******************************@207.46.248.1 6... Maybe I'm just easily baffled after an all-nighter but I can't seem

to figure out how to represent a BitArray as a hexadecimal string.

For example:

Dim outputBank As New BitArray(8)

outputBank(0) = True

outputBank(1) = False

outputBank(2) = False

outputBank(3) = True

outputBank(4) = True

outputBank(5) = False

outputBank(6) = True

outputBank(7) = False

The hexadecimal string for the above array of bits would be "59".

How can I obtain that string? Is there an easy built-in method for

doing this or do I have to build something on my own?
