asp.net 中<% %>、<%@ %>、<%# %>、<%= %>、<%$ %>的用法

<form id="form1" runat="server">  
        <%--绑定后台代码块--%>  
        <% for (int i = 1; i <= 10; i++)  
           { %>  
        <%=i %>  
        <%} %>  
</form>  

namespace WebApplication  
{  
    public partial class Index : System.Web.UI.Page  
    {  
        public string _title = "";  
        protected void Page_Load(object sender, EventArgs e)  
        {  
            if (!IsPostBack)  
            {  
                _title = "标题";  
            }  
        }  
    }  
}  

<form id="form1" runat="server">  
       <asp:Repeater ID="Repeater" runat="server">  
           <ItemTemplate>  
               <span><%# Eval("name") %></span>  
           </ItemTemplate>  
       </asp:Repeater>  
</form>
