//这是静态给categories赋值，怎么动态赋值呢，就是连接数据库后查询数据绑定categories，使他的数据成下面一样显示
            Categories = new List<Category>
            {
                new Category
                {
                    Name = "category 1",
                    Children = new List<Category>
                    {
                        new Category
                        {
                            Name="category 1-1",
                            Children = new List<Category>{}
                        },
                        new Category
                        {
