Question

我有两个仅包含数据的类（设置和凭据）。我不知道该如何称呼这些课程，所以请耐心等待。

数据类示例。

class Settings
{

        public string Host { get; set; }
        public int Port { get; set; }

}


class Credentials
{

        public string UserName { get; set; }
        public string Password { get; set; }

}

我想使用MVC控制器操作创建一个包含这两个数据类的新对象。

对象类的示例。

class Object
{
        private readonly Settings _settings;
        private readonly Credentials _credentials;

        public Object(Settings settings, Credentials credentials)
        {
            _settings = settings;
            _credentials = credentials;
        }
}

我想做的事的例子。

public class HomeController : Controller
{
        public IActionResult Index()
        {
            return View();
        }

        [HttpPost]
        public IActionResult Create(Settings settings, Credentials credentials)
        {
            new Object(settings, credentials);

            return View(Index());
        }
}

我的问题我该如何实现呢？不必将每个参数都放在 IActionResult Create（）方法中。

我的POST表单应该是什么样的？

谢谢。

您几乎完全正确。我将使用的模型：

public class Settings
{
    public string Host { get; set; }
    public int Port { get; set; }

}

public class Credentials
{
    public string UserName { get; set; }
    public string Password { get; set; }
}

class Object
{
    private readonly Settings _settings;
    private readonly Credentials _credentials;

    public Object(Settings settings, Credentials credentials)
    {
        _settings = settings;
        _credentials = credentials;
    }
}

public class ObjectView
{
    public Settings Settings { get; set; }
    public Credentials Credentials { get; set; }
}

控制器动作：

public IActionResult Index()
{
    return View();
}

public IActionResult Create()
{
    return View(new ObjectView());
}

[HttpPost]
public IActionResult Create(ObjectView objectView)
{
    var obj = new Object(objectView.Settings, objectView.Credentials);

    return RedirectToAction("Index");
}

用于创建模型的剃刀视图：

@model ObjectAsParametersInAction.Models.ObjectView
@{
    ViewBag.Title = "View";
}
<h2>View</h2>
@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()
    <div class="form-horizontal">
        <h4>ObjectView</h4>
        @Html.LabelFor(m => m.Credentials.UserName)
        @Html.EditorFor(m => m.Credentials.UserName)
        @Html.LabelFor(m => m.Credentials.Password)
        @Html.EditorFor(m => m.Credentials.Password)

        @Html.LabelFor(m => m.Settings.Host)
        @Html.EditorFor(m => m.Settings.Host)
        @Html.LabelFor(m => m.Settings.Port)
        @Html.EditorFor(m => m.Settings.Port)
        <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", "Index")
</div>
@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

请求中已过帐的表单数据将包含参数，例如：

Credentials.UserName=John&Credentials.Password=Unkown&Settings.Host=127.0.0.1&Settings.Port=80

在创建发布操作中，所有这些都将模型绑定到ObjectView公共属性。

在ASP.NET MVC操作中使用数据类传递许多参数
