请先阅读:)谢谢：)
我有一个称为RMA（http://localhost/User/RMA?Id=132）的视图，它显示了有关产品的一些详细信息，还显示了注释（列表），其中与该产品相关，并且也有可能在同一视图中更新每个评论，但是首先我应该通过id获取评论，然后我可以在同一视图中更新每个评论，但是我确实存在一些问题，无法通过id在同一视图中，我也在其中显示评论列表。让我描述问题：）
控制器：
public ActionResult CommentsId(int? ComID, int? id)
{
//Show Comment per ID
var querythree = (from RH in db.RMA_History
join RB in db.Besked on RH.Id equals RB.RMAID
where RB.ID == ComID && RB.RMAID == id
select new VMRMA
{
RBID = RB.ID,
RBPM = RB.MSG,
RBRMAID = RB.RMAID
});
var q = querythree.FirstOrDefault();
return View(q);
}
查看（CommentsId.cshtml）：
@using ModelNameSpace.Models
@model VMRMA
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>CommentsById</title>
</head>
<body>
<div>
<input type="hidden" name="ComID" value="@Model.RBID" />
<input type="hidden" name="RMAID" value="@Model.RBRMAID" />
<p>@Model.RBPM</p>
</div>
</body>
</html>
为RMA的视图，用户单击更新链接：
@using NameSpace.Models
@model VMRMA
//Loop Comments
@foreach (var item in Model.Comment_Lists)
{
<h3 class="h5">@item.PM</h3>
//Link
<a href="/User/CommentsId?ComID=@item.ID&id=@item.RMAID">Update</a>
}
控制器：
public ActionResult _CommentsById(int? ComID , int? id)
{
var querythree = (from RH in db.RMA_History
join RB in db.Besked on RH.Id equals RB.RMAID
where RB.ID == ComID && RB.RMAID == id
select new VMRMA
{
RBID =RB.ID,
RBPM =RB.MSG,
RBRMAID=RB.RMAID
});
var q = querythree.FirstOrDefault();
return PartialView("_CommentsById", q);
}
PartialView（_CommentsById.cshtml）：
@using ModelNameSpace.Models
@model VMRMA
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>CommentsById</title>
</head>
<body>
<div>
<input type="hidden" name="ComID" value="@Model.RBID" />
<input type="hidden" name="RMAID" value="@Model.RBRMAID" />
<p>@Model.RBPM</p>
</div>
</body>
</html>
View RMA，在其中渲染PartialView：
@using NameSpace.Models
@model VMRMA
//Select From Parent Model HRMAS
<input type="text" class="form-control disabled" value="@Model.HRMAs.FirmaNavn">
//Loop Comments list
@foreach (var item in Model.Comment_Lists)
{
<h3 class="h5">@item.PM</h3>
//Link
<a data-toggle="modal" data-target="#myModal" href="/User/_CommentsById?ComID=@item.ID&id=@item.RMAID">Update</a>
}
<div class="container">
<!-- Modal -->
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">
<!-- Modal content--
<div class="modal-content">
<div class="modal-header">
