如何将嵌套循环转换为ListViews

Question

我试图显示一个对象数组，每个对象实例都包含数组。

我使用了scriptlet，它可以完美运行，但是我并不是这些的忠实拥护者。 ListView是我尝试实现的，但没有找到第二个循环的解决方案。

一些解释：

• 第一个循环显示每个用户名
• 第二个显示用户从“开始日期”到“结束日期”的每个月的薪金

这是用户界面

            %>
        </div>
    </div>
</asp:Content>

然后是后面的代码

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

namespace UserManagement.Data
{
    public partial class SalaryBetweenDate : System.Web.UI.Page
    {
        public User[] otherAccessibleUsers = null;
        public User[] allUsers = null;
        public SalaryRising[] allSalaryRisings = null;
        public Model.SalaryBetweenDate[] display = null;

        protected void Page_Load(object sender, EventArgs e)
        {
            PageProtection pageProtection = new PageProtection();

            if (Session["UserId"] != null)
            {

            }
            else
            {
                pageProtection.NotConnected(Session, Server, Request, Response);
            }
        }

        protected void Unnamed_Click(object sender, EventArgs e)
        {
            allUsers = (User[])Session["allUsers"];
            allSalaryRisings = (SalaryRising[])Session["allSalaryRisings"];
            CalculatedElementUser[] allElements = (CalculatedElementUser[])Session["allCalculatedElementUser"];
            User user = (User)Session["user"];
            otherAccessibleUsers = user.GetOtherUsersInformation(allUsers);
        }
    }
}
