在我最近使用Asp.net Mvc 2的項目中,我們發現DisplayFor存在性能問題。我不太確定這是真實問題還是我錯過了什麼?Asp.net Mvc 2 DisplayFor性能問題?
我希望一些Asp.net Mvc Guru可以給我解釋一下。 :)
型號。
public class Customer
{
public int CustomerId { get; set; }
public string Name { get; set; }
public string Address { get; set; }
public string EmailAddress { get; set; }
public static IEnumerable<Customer> GetCustomers()
{
for (int i = 0; i < 1000; i++)
{
var cust = new Customer()
{
CustomerId = i + 1,
Name = "Name - " + (i + 1),
Address = "Somewhere in the Earth...",
EmailAddress = "customerABC"
};
yield return cust;
}
}
}
控制器
public ActionResult V1()
{
return View(Customer.GetCustomers());
}
public ActionResult V2()
{
return View(Customer.GetCustomers());
}
V1(其中有性能問題)
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<Customer>>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
V1
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>V1</h2>
<table>
<%foreach (var cust in this.Model)
{%>
<%= Html.DisplayFor(m => cust) %>
<%} %>
</table>
</asp:Content>
而且模板是
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Customer>" %>
<tr>
<td><%= this.Model.CustomerId %></td>
<td><%= this.Model.Name %></td>
<td><%= this.Model.Address %></td>
<td><%= this.Model.EmailAddress %></td>
</tr>
V2(無性能問題)
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<Customer>>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
V2
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>V2</h2>
<table>
<%foreach (var cust in this.Model)
{%>
<tr>
<td><%= cust.CustomerId%></td>
<td><%= cust.Name%></td>
<td><%= cust.Address%></td>
<td><%= cust.EmailAddress%></td>
</tr>
<%} %>
</table>
</asp:Content>
我可以很容易地看到V1和V2之間的性能差異。
編輯:當我部署到我的本地IIS 7(與發行版),它(V1)變得非常快。問題解決了,但我仍然想知道原因。 :)

謝謝!我將調試切換爲false,並且性能回到了我的預期... – bytebender
