假设返回泛型集合的方法是GetData():<asp:GridView ID="GridView1" runat="server" >
</asp:GridView><script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
GridView1.DataSource = GetData();
GridView1.DataBind();

Answer 6

我写的  献丑了  List<Dictionary<string, List<Categories>>> list = CategoriesManage.GetCategories();//获取泛型集合
            Dictionary<string, List<Categories>> dic = list[0];
                foreach (string s in dic.Keys)
                {
                    List<Categories> list1 = dic[s];
                    Table tb = new Table();
                    for (int i = 0; i <= 1; i++)
                    {
                        if (i == 0)
                        {
                            TableRow tr = new TableRow();
                            tb.Rows.Add(tr);
                            TableCell td = new TableCell();
                            tr.Cells.Add(td);
                            td.ToolTip = s;
                            td.Text = s+"<hr>";
                            if (td.Text.Length > 4)
                            {
                                td.Text = td.Text.Substring(0, 4) + "...<hr>"; ;
                            }
                            td.Text="<B>"+td.Text+"</B>";
                        }
                        else
                        {
                            int a = 0; 
                            TableRow tr1=null;
                            foreach (Categories c1 in list1)
                            {
                                TableCell td1 = new TableCell();
                                if (a % 3 == 0)
                                {
                                    tr1 = new TableRow();
                                    tb.Rows.Add(tr1);
                                    tr1.Cells.Add(td1);
                                    td1.ToolTip = c1.Name;
                                    td1.Text = c1.Name;
                                    if (td1.Text.Length > 4)
                                    {

                                    }
                                }
                                td1.Text = "<a href='BookList.aspx?typeid="+c1.Id+"'>" + td1.Text + "</a>";
                                a++;
                            }
                        }
                    }
                    this.P1.Controls.Add(tb);                    if (IsPostBack)//保持单选按钮的状态
                    {
                        try
