asp.net web中一个页面去调用执行另一个页面

HttpServerUtility.Execute 方法

HttpServerUtility.Execute 方法是个很有用的方法，可以直接执行一个aspx页，然后返回一个字符串，当然也可以执行用户控件；

文章：Asp.Net Server.Execute、Server.Transfer报“执行子请求时出错”解决方案

示例代码：

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace TestWebpageExec
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

            StringWriter sw = new StringWriter();
            HttpContext.Current.Server.Execute("/WebForm2.aspx", sw,false);
          
            
            string resultStr = sw.ToString();
           
            int a = 0;
        }
    }
}

resultStr就是执行另一个页面返回的字符串；

另一个页面的代码：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="TestWebpageExec.WebForm2" %>

<table>
    <tr>
        <td>名字</td>
        <td>年龄</td>
    </tr>
    <%
        if (ListStudent != null && ListStudent.Count > 0)
        {
            foreach (var stu in ListStudent)
            {
                %>
                    <tr>
                        <td><%=stu.Name %></td>
                        <td><%=stu.Age%></td>
                    </tr>
                <%
            }
        }

    %>
    
</table>

后台代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace TestWebpageExec
{
    public partial class WebForm2 : System.Web.UI.Page
    {
        public List<Student> ListStudent = new List<Student>();
        protected void Page_Load(object sender, EventArgs e)
        {
            ListStudent.Add(new Student() { Age=11,Name="tom" });
            ListStudent.Add(new Student() { Age = 12, Name = "xiao" });
            ListStudent.Add(new Student() { Age = 13, Name = "long" });
            ListStudent.Add(new Student() { Age = 10, Name = "yang" });
            ListStudent.Add(new Student() { Age = 9, Name = "hui" });
        }
    }

    public class Student
    {
        public string Name { get; set; }

        public int Age { get; set; }
    }
}
