AsciiEncode - Convert a string to its ASCII representation

' Convert a string to its ASCII representation
' Example: Response.Write(AsciiEncode("hello"))
'   ==> hello
'
' Note: this may be useful when you're producing the code for HTML forms with 
' hidden/visible field, and you want to make a little more difficult for the 
' user to understand the name (you can also "encrypt" the name,
'  not just the value) and value of those fields, if they look at the page's 
' source code. The browser will correctly interpret the values anyway.

Function AsciiEncode(ByVal value As String) As String
    Dim encValue As New System.Text.StringBuilder(value.Length * 6)
    Dim c As Char
    ' encode each char to its ASCII representation
    For Each c In value
        encValue.Append("&#")
        encValue.Append(Convert.ToInt32(c))
        encValue.Append(";")
    Next
    Return encValue.ToString()
End Function
