FileAttributes.hidden problem

I have to display the attributes of a file in a lits box. I am using the attached code to get the attribute.

The problem I am getting is that even though I have set a known file to Hidden, i get the error message shown in the attached image.

If I change fi.attributes to FileAttributes, it always sets fileHidden to "False"

Can someone please enlighten me to what I am doing wrong?

(I am doing stuff like ensuring the file exists etc before testing the attributes)
Dim fi As New FileInfo(fileName)
                If fi.Attributes.Hidden() = True Then
                    fileHidden = "True"
                Else
                    fileHidden = "False"
                End If

As the attributes enum is bitwise, you have to check if the Hidden Attribute is set this way:
Dim fileHidden As Boolean = (fi.Attributes And FileAttributes.Hidden) = FileAttributes.Hidden

Try this way
        Dim fi As New FileInfo(fileName)
        If fi.Attributes = FileAttributes.Hidden Then
            fileHidden = "True"
        Else
            fileHidden = "False"
        End If

The problem with that is that if the file has several attributes set, (fi.Attributes = FileAttributes.Hidden) == false
