binary outputs are different in hash SHA256

SHA256 hashing output is different in two codes, input is same so outputs should be identical, the code seems to be fine, I can't understand why it produces different results. What is wrong with it?

VB.NET CODE

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim temphashstring As String = "1a"
        temphashstring = hashed(temphashstring)
        T7.Text = StringToAsciiBits(temphashstring)

End Sub

Public Function StringToAsciiBits(ByVal inputstring As String) 'Convert string text to binary text

        Dim bitsAsString As String
        Dim Re As New System.Text.StringBuilder
        For Each Character As Byte In System.Text.ASCIIEncoding.ASCII.GetBytes(inputstring)
            Re.Append(Convert.ToString(Character, 2).PadLeft(8, "0"))
            'Re.Append(" ") 'put one space (" ") after every 8 bits to view easily by human eye
        Next
        bitsAsString = Re.ToString.Substring(0, Re.ToString.Length - 0)


        Return bitsAsString
    End Function

Public Function hashed(ByVal inputstring As String) As String

        'Encode by UTF8
        Dim pt As New System.Text.UTF8Encoding
        Dim ptBytes() As Byte = pt.GetBytes(inputstring)
        Dim ptSBytes() As Byte = New Byte(ptBytes.Length - 1) {}
        'Copy plaintext bytes to array.
        Dim num As Integer
        Dim hash As HashAlgorithm
        'hashing algorithm class.
        hash = New SHA256Managed()
        ' Compute hash

        For num = 0 To ptBytes.Length - 1
            ptSBytes(num) = ptBytes(num)
        Next num

        Dim hashBytes As Byte()
        hashBytes = hash.ComputeHash(ptSBytes)
        ' Convert into a base64-encoded string.

        Dim hashValue As String
        hashValue = Convert.ToBase64String(hashBytes)
        hashed = hashValue 'return hashvalue
    End Function

Input: 1a
