高手请进-》下拉列表的数据源问题？？？？？？？

实现点击dropdownlist按钮，从中选择1900-2009（即datetime.today.year）,用数组实现      
            String[] Year;
            Year = new string[DateTime.Today.Year + 1];
            for (int i = 1900; i <= DateTime.Today.Year; i++)
            {
                Year[i] = "i";
            }          
            DropDownList1.DataSource =Year;
            DropDownList1.DataBind();
            DropDownList1.SelectedIndex = 0;
有其他方法也行，谢谢！！！！  --------------------编程问答-------------------- for (int i = 1900; i <= DateTime.Today.Year; i++)
            {
                ListItem item = new ListItem();
                DropDownList1.Items.Add(item);
            }   --------------------编程问答-------------------- for (int i = 1900; i <= DateTime.Today.Year; i++) 
            { 
                DropDownList1.Items.Add(i.ToString());

 DropDownList1.Items.Insert(0,"--请选择--");
