如何遍历相关模型以创建单个MVC视图 [英] How to iterate through related models to create a single MVC view
问题描述
大家好，我是ASP MVC的新手，我正在做宿舍管理项目用于学习目的。我只使用ADO.NET（没有EF没有Linq）。我有两个模型居民和分配。我试图在同一视图中显示居民和分配（房间预订）。
在我的下面的代码中，我想显示来自Resident表的Resident信息（名字，姓氏和电子邮件），该表与Allocations表相关有关房间的信息。
在控制器中，我试图通过列表获取居民的信息然后检查，是否有任何分配给该居民的房间。
非常感谢任何帮助，提前谢谢。
我尝试了什么： < br $>
public ActionResult ManageResidents（）
{
List< resident> mlist = new List< resident>（）;
ResidentDB db = new ResidentDB（）;
mlist = db.ResidentSelectAll（）;
foreach（mlist中的居民）
{
分配mAllocation = new Allocation（）;
AllocationDB db2 = new AllocationDB（）;
mAllocation =
db2.AllocationSelect（rs.ResidentAllocation.AllocationID）;
rs.ResidentAllocation = mAllocation;
mlist.Add（rs）;
}
ViewBag.Residents = mlist;
返回查看（mlist）;
}
Hello Everyone, I am new to ASP MVC, I am doing the Hostel Management project for learning purposes. I am only using ADO.NET (no EF no Linq). I have two Models Residents and Allocations. I am trying to show the Residents and Allocations (room booking) in the same view.
In my code below, I want to show Resident's information (first name, last name, and email) from Resident's table which is related to the Allocations table, which holds the information about rooms.
In the controller, I am trying to get the resident's information using lists and then check, is there any room allocated to that resident or not.
Will greatly appreciate any help, thanks in advance.
What I have tried:
public ActionResult ManageResidents()
{
List<resident> mlist = new List<resident>();
ResidentDB db = new ResidentDB();
mlist = db.ResidentSelectAll();
foreach (Resident rs in mlist)
{
Allocation mAllocation = new Allocation();
AllocationDB db2 = new AllocationDB();
mAllocation =
db2.AllocationSelect(rs.ResidentAllocation.AllocationID);
rs.ResidentAllocation = mAllocation;
mlist.Add(rs);
}
ViewBag.Residents = mlist;
return View(mlist);
}
