如何在视图中检索tempdata值？ [英] how to retrieve tempdata values in a view?
问题描述
控制器中的代码：
公共ActionResult索引（FormCollection表单，员工员工）
{
BusinessLogic logic = new BusinessLogic（）;
employee.Name = form [Name];
employee.Gender = form [性别];
employee.City = form [City];
employee.Dateofjoining = Convert.ToDateTime（form [Dateofjoining]）;
TempData [EmployeeDetails] =员工;
logic.AddEmployee（员工）;
返回View（）;
}
这里我创建了另一个操作方法，将上述tempdata值传递给review操作方法以及如何检索值使用tempdata。
code in controller:
public ActionResult Index(FormCollection form,Employee employee)
{
BusinessLogic logic = new BusinessLogic();
employee.Name = form["Name"];
employee.Gender = form["Gender"];
employee.City = form["City"];
employee.Dateofjoining = Convert.ToDateTime(form["Dateofjoining"]);
TempData["EmployeeDetails"] = employee;
logic.AddEmployee(employee);
return View();
}
and here i have create another action method to pass the above tempdata values to the review action method and how to retrieve the values using tempdata.
public ActionResult review()
{
}
和vie对于指数行动方法的w是：
@model BusinessLayer.Employee
@ {
ViewBag.Title =索引;
}
索引
@using（Html.BeginForm（））{
@ Html.AntiForgeryToken（）
@ Html.ValidationSummary（true）
员工
and view for Index action method is :
@model BusinessLayer.Employee
@{
ViewBag.Title = "Index";
}
Index
@using (Html.BeginForm()) {
@Html.AntiForgeryToken()
@Html.ValidationSummary(true)
Employee
@ Html.LabelFor（model => model.Name）
@Html.LabelFor(model => model.Name)
@ Html.EditorFor（model => ; model.Name）
@ Html.ValidationMessageFor（model => model.Name）
@Html.EditorFor(model => model.Name)
@Html.ValidationMessageFor(model => model.Name)
@ Html.LabelFor（model => model.Gender）
@Html.LabelFor(model => model.Gender)
@ Html.EditorFor（model => model.Gender）
@ Html.ValidationMessageFor（model => model.Gender）
@Html.EditorFor(model => model.Gender)
@Html.ValidationMessageFor(model => model.Gender)
@ Html.LabelFor（model => model.City）
@Html.LabelFor(model => model.City)
@ Html.EditorFor（model => model.City）
@ Html.ValidationMessageFor（model => model.City）
@Html.EditorFor(model => model.City)
@Html.ValidationMessageFor(model => model.City)
@ Html.LabelFor（model => model.Dateofjoining）
@Html.LabelFor(model => model.Dateofjoining)
@ Html.EditorFor（model => ; model.Dateofjoining）
@ Html.ValidationMessageFor（model => model.Dateofjoining）
@Html.EditorFor(model => model.Dateofjoining)
@Html.ValidationMessageFor(model => model.Dateofjoining)
< input type =submitvalue =创建/>
<input type="submit" value="Create" />
@ Html.ActionLink（返回列表，索引 ）
@Html.ActionLink("Back to List", "Index")
推荐答案
阅读本文：什么是ViewData，ViewBag和TempData？ - 用于在当前和后续请求之间传递数据的MVC选项 [ ^ ]
您应该考虑的是，TempData的生命周期非常短，不会在请求之间传递。它用于其他东西...
另一方面，为什么你在TempData中传递模型？
返回查看（员工）;
是这样做的方法......
Read this article: What is ViewData, ViewBag and TempData? – MVC options for passing data between current and subsequent request[^]
What you should consider, is that TempData has a very short lifecycle, it is not passed between requests. It is meant for something else...
On the other hand why do you pass the model in TempData?
return View(employee);
is the way to do it...
