Converting string into byte

Question

How do i turn this string into binary without going through the decimal number system first. So I have.

Dim test as string = "11111111"
' And a text field called mask1
mask1.text = Convert.ToByte(m1)
' Then i get an overflow exception everytime

What is m1? Did you mean to pass the string test into Convert.ToByte? — Jeff B

I think the string is a representation of a Byte number in binary number format and he wants to convert this into an actual number (in this case 256). @user: your code tries to assign the number 11111111 (11 million) to a byte variable that goes from 0 to 255, that's what causes the exception at least. — Jens

You appear to have forgotten to use the number base in the Convert.ToByte method:

Dim s As String = "11111111"
Dim b As Byte = Convert.ToByte(s, 2)
Console.WriteLine(b) ' outputs "255"
