Answer 1

DictionaryEntry de = new DictionaryEntry();

        DropDownList ddl = new DropDownList();
        ddl.Items.Add(new ListItem(de.Value.ToString(), de.Key.ToString()));

Answer 2

貌似不能直接绑定，你可以循环Dictionary 键值，然后加到table或者加进类数组也可

Answer 3

参考:  protected void Button1_Click(object sender, EventArgs e)
    {
        DropDownList1.DataTextField = "value";
        DropDownList1.DataValueField = "key";
        DropDownList1.DataSource = GetTypeList();
        DropDownList1.DataBind();
        DropDownList1.Items.Insert(0, new ListItem("请选择"));
    }    protected Dictionary<int, string> GetTypeList()
    {
        Dictionary<int, string> list = new Dictionary<int, string>();
        list.Add(1, "one");
        list.Add(2, "two");
        list.Add(3, "three");
        list.Add(4, "four");
        return list;
    }
