dataGridView 显示一类里别一个类的属性

        本代码 实现 的是     dataGridView   手动添加  的

                   这个代码的功能 主要实现  一个实体类 定义了其他的实体类   用下面的代码可以读去其他实体类的属性

 

                List<Merchandise> splist = null; //对象
                dataGridView6.DataSource = null; // dataGridView
                splist = new List<Merchandise>(); //范行
                ArrayList lists = new ArrayList();// lists 的范行
                splist = spgl.FindMerchandiseInfo(); // 掉一个方法反会 LIST
               
                dataGridView6.ColumnCount = 8; //   给他8 个
                dataGridView6.Columns[0].Name = "编号";// 给他取名字
                dataGridView6.Columns[1].Name = "姓名";//
                dataGridView6.Columns[2].Name = "年龄";//
                dataGridView6.Columns[3].Name = "好多系";
                dataGridView6.Columns[4].Name = "战士";
                dataGridView6.Columns[5].Name = "刀子";
                dataGridView6.Columns[6].Name = "发射";
               
                //  遍历splist
                // 给一个arraylist 
                //然后在用 一个  lists 来添加 arraylist
                foreach(Merchandise stu in splist)
                {                  
                    ArrayList arlist = new ArrayList();
                    arlist.Add(stu.MId);//ID
                    arlist.Add(stu.MName);//名称
                    arlist.Add(stu.Money);//单价
                    arlist.Add(stu.Peculiar);//特别费用
                    arlist.Add(stu.StockPile);//库存
        arlist.Add(stu.Qtclass.QTclass);//商品类型    这里看见没  就是其他类的属性   数据成那里  做该动 就可以读取了
                    arlist.Add(stu.Units);//规格               
                    lists.Add(arlist);
                }
                // 着里也是遍历
                foreach (ArrayList stus in lists)
                {
                    string now1 = stus[0].ToString();
                    string now2 = stus[1].ToString();
                    string now3 = stus[2].ToString();
                    string now4 = stus[3].ToString();
                    string now5 = stus[4].ToString();
                    string now6 = stus[5].ToString();

                    string[] row1 = new string[] { now1, now2,now3,now4,now5,now6 };

                    object[] row2 = new object[] { row1 };

                    foreach (string[] rowArrayin in row2)
                    {
                        dataGridView6.Rows.Add(rowArrayin);
                    }
                }
