Convert from string to binary in VB.NET

Let's say that I have the string "A3C0", and I want to store the binary value of it in a Boolean array.

After the conversion (from string to binary) the result should be = 1010001111000000

Then I want to store it in this array,

dim bits_array(15) as Boolean

at the end:

bits_array(0)=0
bits_array(1)=0
 .
 .
 .
 .
bits_array(15)=1

How can I do this?

It's easy.

Function HexStringToBinary(ByVal hexString As String) As String
    Dim num As Integer = Integer.Parse(hexString, NumberStyles.HexNumber)
    Return Convert.ToString(num, 2)
End Function

Sample Usage:

Dim hexString As String = "A3C0"
Dim binaryString As String = HexStringToBinary(hexString)
MessageBox.Show("Hex: " & hexString & "    Binary: " & binaryString)

To get the binary digits into an array, you can simply do:

Dim binaryDigits = HexStringToBinary(hexString).ToCharArray

Let s be the input string with value A3C0, output be a variable to store the output. loop will iterate each letter in the input and store it in the temporary variable temp. Now see the code: 

Dim s As String = "A3C0"
Dim output As String = ""
Dim temp As String = ""
For i As Integer = 1 To Len(s)
    temp = Mid(s, i, 1)
    output = output & System.Convert.ToString(Asc(temp), 2).PadLeft(4, "0")
    ' converting each letter into corresponding binary value
    'concatenate it with the output to get the final output 
Next
MsgBox(output)' display the binary equivalent of the input `s` 
Dim array() As Char = output.ToArray()' convert the binary string  to binary array

Hope that this is actually you are expected.
