vb.net - ASCII to Base32

Question

I am working at making what 10 characters go into a text box in my vb project convert into Base32. Here is my code. I am getting an error Value of type 'String' cannot be converted to 'Byte()'. WindowsApplication2

Private Sub Ok_Click(sender As Object, e As EventArgs) Handles Ok.Click

Dim DataToEncode As Byte() = txtbox.Text

Dim Base32 As String
Base32 = DataToEncode.ToBase32String()
Auth.Text = Base32
End Sub

Answer 1

The value in txtbox.Text is a string which can't be automatically converted to a byte array. So the line Dim DataToEncode As Byte() = txtbox.Text can't be compiled. To get the ASCII representation of a string use the System.Text.Encoding.ASCII.GetBytes() method.

Dim DataToEncode As Byte() = System.Text.Encoding.ASCII.GetBytes(txtbox.Text)

Also strings in VB.Net do not store ASCII values, they use UTF-16.
