Try:

VB

Using con As SqlConnection = New SqlConnection(strConnect)
    con.Open()
    Using cmd As SqlCommand = New SqlCommand("SELECT myDateColumn FROM myTable WHERE rowID = @RI", con)
        cmd.Parameters.AddWithValue("@RI", valueWhichSelectsTheRightRow)
        Using reader As SqlDataReader = cmd.ExecuteReader()
            While reader.Read()
                Dim dt As DateTime = CType(reader("myDateColumn"), DateTime)
                Console.WriteLine(dt)
            End While
        End Using
    End Using
End Using
