Question

所以我目前正在学习ASP.net MVC的工作，而且我只是在玩它来学习一些东西。目前，我有一个网页，其中提供了来自C＃代码（模拟数据库）的硬编码列表和一个显示菜单的创建按钮，允许我为新人添加信息，然后单击创建按钮在底部添加它。但是，创建按钮当前不起作用。如何创建一个方法来获取该输入并将其添加到列表中，此外，该方法应该在哪里？ PersonController？ PersonModel？谢谢你的帮助！

    namespace ASPpractice.Controllers
    {
        public class PersonController : Controller
        {

    List<PersonModel> people = new List<PersonModel>();

    // GET: Person
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult Person()
    {


        people.Add(new PersonModel {Age = 76, Name = "Rick", Title = "Drunk Mad Scientist"});
        people.Add(new PersonModel {Age = 13, Name = "Morty", Title = "Tool of a Grandson"});
        people.Add(new PersonModel {Age = 35, Name = "Jerry", Title = "Unemployed Dumbass Father"});

        return View(people);
    }

    public ActionResult Create()
    {
        return View();
    }
}

}

    namespace ASPpractice.Models
    {
        public class PersonModel
       {
    private string _Name;
    private string _Title;
    private int _Age;

    public string Name { get { return _Name; } set { this._Name = value; }}
    public string Title { get { return _Title; } set { this._Title = value; } }
    public int Age { get { return _Age; } set { this._Age = value; } }

}

}

@model ASPpractice.Models.PersonModel

@{
    ViewBag.Title = "Create";
 }

 <h2>Create</h2>


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

<div class="form-horizontal">
    <h4>PersonModel</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.Title, htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.EditorFor(model => model.Title, new { htmlAttributes = new { @class = "form-control" } })
            @Html.ValidationMessageFor(model => model.Title, "", new { @class = "text-danger" })
        </div>
    </div>

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

}

<div>
    @Html.ActionLink("Back to List", "Person")
</div>

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")

Answer 1

public ActionResult Create(){}
[HttpPost]
public ActionResult Create(PersonModel model)
{
    people.Add(new PersonModel {Age = model.Age, Name = model.Name, Title =model.Title});
    return View();
}

Answer 2

网站是基于请求的 ....所以您要将其添加到的列表不能存在于您的控制器中，因为控制器已创建e ach time请求控制器中的操作。

这实际上会重置您的列表。

您需要创建一个可从任何地方访问的静态列表....

Answer 3

您需要做的是在Controller中调用一个方法来填充列表。一目了然，您的 EditorFors 应该没问题，并正确填充您的模型。

使用

@using (Html.BeginForm("ActionMethod","Controller",FormMethod.Post))

会调用您的ActionMethod，您应该接受 PersonModel 。

public ActionResult ActionMethod(PerosnModel vm)...

在那里，您可以使用提交的模型执行所需操作。（即将其添加到db表，发布，保存或显示）。

希望这有帮助。

从网站获取输入并将其添加到C＃列表
