How to access a UDT from outside SAP

Hi experts, I'm trying to access a UDT and display its contents in a DataGridView using C# in MSVS 2013.  I have a successful connection to the database.  The command

SELECT * FROM dbo.[@FOAMSPECS]

works from both SAP's Query Preview window and from the Microsoft SQL Server Management Studio's query window.  So after much trying to correctly escape the brackets, I came up with this code snippet

            OleDbDataReader dr;

            string SqlCommand = "SELECT * FROM dbo.[[@FOAMSPECS]]]";

            // Fill listbox with foam specs

            OleDbCommand cmd = new OleDbCommand { CommandText = SqlCommand, Connection = cn };

            try

            {

                dr = cmd.ExecuteReader();

            }

            catch (Exception ex)

            {

                MessageBox.Show("SQL Error ! " + ex.Message);

            }

This seems to produce brackets in the right place in the select string but I get this error

What am I missing?
