Question

我正在尝试将用户在“创建”视图中输入的详细信息转移到另一个视图“确认”代码如下：

创建操作结果

public ActionResult Create()
    {

        return View(new Charity());
    }

 [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create([Bind(Include = "ID,DisplayName,Date,Amount,Comment")] Charity charity)
    {

        if (ModelState.IsValid)
        {
            if (!string.IsNullOrEmpty(charity.Comment))
            {
                var comment = charity.Comment.ToLower().Replace("hot", "###").Replace("cold", "###").Replace("Slow", "###").Replace("enjoy", "###").Replace("BAD", "###");
                charity.Comment = comment;  //Replaces textx from model variable - comment

                charity.TaxBonus = 0.20 * charity.Amount;

            }

            if (string.IsNullOrEmpty(charity.DisplayName))
            {
                charity.DisplayName = "Annonymus"; //If user doesnt enter name then Annonymus


            }


            db.Donations.Add(charity);
            db.SaveChanges();
            return RedirectToAction("Confirmation", "Charities" , new { id = charity.ID });
        }
        return View(charity);
    }

创建视图

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

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

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

            </div>
        </div>

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

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

AdditionalInfo ActionResult

[HttpGet]
    public ActionResult Additionalinfo(int id)
    {

        return View("Additionalinfo", new { id });
    }

其他信息视图

@{
    ViewBag.Title = "Additionalinfo";
}

<h2>Additionalinfo</h2>

模型

  public class Charity
{
    public int ID { get; set; }
    [RegularExpression(@"^[a-zA-Z]+$", ErrorMessage = "Use letters only please")]
    public string DisplayName { get; set; }

    [DataType(DataType.Currency)]
    [Range(2, Int32.MaxValue, ErrorMessage = "Atleast £2.00 or a whole number please")]
    public int Amount { get; set; }
    [DataType(DataType.Currency)]
    public Double TaxBonus { get; set; }
    public String Comment { get; set; }
}

public class CharityDBContext : DbContext //controls information in database 
{
    public DbSet<Charity> Donations { get; set; } //creates a donation database
}

您好我正在尝试从“创建”中输入的信息显示在“确认”中，我可以只显示数据库，但我想要的是要传递到下一页的具体信息，而不是整个数据库。我是MVC的新手，所以试图掌握这一点。

我在新的ActionResult上创建了它，但是我无法使传递的数据生效。

Answer 1

您可以使用会话：

var products=Db.GetProducts();

//Store the products to a session
Session["products"]=products;

//To get what you have stored to a session
var products=Session["products"] as List<Product>;

如何将特定数据从一个视图传输到另一个视图
