I cant get sql read to work.

In my code I can open a sql channel ok.

However I cant get it to read a table with a username and password field.

I get username not a valid object error.

            string connectionString = @"Server = (localdb)\MSSQLLocalDB; connect timeout=30; database=Database1; Integrated Security = false; ";


            SqlConnection connection = new SqlConnection();
            
                connection.ConnectionString = connectionString;

                try
                {
                    connection.Open();
                }
                catch (Exception err)
                {
                    Console.WriteLine(err.ToString());
                }
            
  





            try
            {
                SqlDataReader myReader = null;
                SqlCommand myCommand2 = new SqlCommand(
                "SELECT * from [username];", connection);



                myReader = myCommand2.ExecuteReader();
                while (myReader.Read())
                {
                    TextBox1.Text = myReader["username"].ToString();
                }
            }
            catch (Exception er)
            {
                Console.WriteLine(er.ToString());
            }
