Question

我有一个收集大量数据的表单。所有数据都存储在模型对象中。

提交表单后，如果通过验证，模型将传递到确认视图，该视图只显示表单中提交的所有信息。

[HttpPost]
    public ActionResult ClientProfile(ClientProfileFormModel model)
    {
        if (ModelState.IsValid)
        {
            return View("ClientProfileConfirmation",model);
            }

        return View(model);
    }

当用户点击底部的提交按钮时，我需要模型进入操作，以便我发送电子邮件。

[HttpPost]
    public ActionResult ClientProfileConfirmationSubmit(ClientProfileFormModel model)
    {

        string emailToAdminBody = GenerateFirmProfileAdminEmail(model);
        EmailLogic.Instance.SendEmail("test@test.com", "test@test.com", "Firm profile from " + model.FirmAddress.Name, emailToAdminBody);

        return View(model);
    }

我的问题是：我需要一种简单的方法来从表单的HttpPost操作中获取我的模型（在验证后将其发送到确认页面）到确认的HttpPost操作。我想避免使用隐藏的输入填充确认视图，以便我可以通过表单将其全部写入。

我也尝试将模型存储在Session AND TempData中，但由于某种原因，这两种方式都返回null。我认为这与经历多项行动有关。

这真的不应该那么难！我错过了什么？是将一堆隐藏的输入字段放入确认页面形式的唯一方法吗？

我使用过TempData，它工作正常。

模特：

public class ClientProfileFormModel
{
    public string Name { get; set; }
    public string Address { get; set; }
    public string Country { get; set; }
}

控制器：

public class ClientController : Controller
{
    // GET
    public ActionResult ClientProfile()
    {
        return View();
    }

    [HttpPost]
    public ActionResult ClientProfile(ClientProfileFormModel model)
    {
        if (ModelState.IsValid)
        {
            return RedirectToAction("ClientProfileConfirmation", model);
        }

        return View(model);
    }

    // GET
    public ActionResult ClientProfileConfirmation(ClientProfileFormModel model)
    {
        return View(model);
    }

    [HttpPost]
    public ActionResult ClientProfileConfirmation()
    {
        var model = (ClientProfileFormModel) TempData["clientProfile"];
        string emailToAdminBody = GenerateFirmProfileAdminEmail(model);
        EmailLogic.Instance.SendEmail(...);

        TempData["success-message"] = "Your profile has been approved. Check your inbox.";
        return View("ClientProfileConfirmation", model);
    }
}

ClientProfile视图

@model StackOverflow.Models._31465719.ClientProfileFormModel

@{
    ViewBag.Title = "ClientProfile";
}

<h2>ClientProfile</h2>

@using (Html.BeginForm()) 
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">
        <h4>ClientProfileFormModel</h4>
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        <div class="form-group">
            @Html.LabelFor(model => model.Name, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Name, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Name, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.Address, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Address, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Address, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.Country, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Country, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Country, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Create" class="btn btn-default" />
            </div>
        </div>
    </div>
}

ClientProfile确认视图：

@model StackOverflow.Models._31465719.ClientProfileFormModel

@{
    TempData["clientProfile"] = Model;
    ViewBag.Title = "ClientProfileConfirmation";
    var successMessage = TempData["success-message"];
}

<h2>ClientProfileConfirmation</h2>

@if (successMessage != null)
{
    <div class="alert alert-success">
        <p class="text-success">@successMessage</p>
    </div>
}

@using (Html.BeginForm())
{
    <div>
        <h4>ClientProfileFormModel</h4>
        <hr />
        <dl class="dl-horizontal">
            <dt>
                @Html.DisplayNameFor(model => model.Name)
            </dt>

            <dd>
                @Html.DisplayFor(model => model.Name)
            </dd>

            <dt>
                @Html.DisplayNameFor(model => model.Address)
            </dt>

            <dd>
                @Html.DisplayFor(model => model.Address)
            </dd>

            <dt>
                @Html.DisplayNameFor(model => model.Country)
            </dt>

            <dd>
                @Html.DisplayFor(model => model.Country)
            </dd>

        </dl>
    </div>

    <div class="form-group">
        <div class="col-md-offset-2 col-md-10">
            <input type="submit" value="Confirm" class="btn btn-default" />
        </div>
    </div>
}

我在上一个确认视图中所做的就是将模型保存在TempData中：

TempData["clientProfile"] = Model;

然后在控制器中阅读：

var model = (ClientProfileFormModel) TempData["clientProfile"];

将模型通过视图传递到另一个操作而不编辑
