Question

我是MVC的新生，所以我遇到了一些问题。我想创建创建表单，我可以在其中插入一些信息，如国家，地区等，然后将其序列化到文件。但我的创建方法得到的对象没有任何错误。所以我错了？

 [HttpPost] // This is my Method which must Serialize class Address
    public ActionResult Create(Address address)
    {
        if (ModelState.IsValid)
        {
            // Размещаем в XML данные
            System.Xml.Serialization.XmlSerializer writer =
                new System.Xml.Serialization.XmlSerializer(typeof(Address));

            System.IO.StreamWriter file = new System.IO.StreamWriter(@"c:\MvcApp.xml");
            writer.Serialize(file, address);
            file.Close();
            return RedirectToAction("Index");
        }
        return View(address);
    }

这是我的查看文件

 @model WorkWithAddresses.Models.Address

 @{
ViewBag.Title = "Create";
 }

 <h2>Create</h2>

 @using (Html.BeginForm())
 {
@Html.ValidationSummary(true)
    <fieldset>
        <legend>Address</legend>
        <div class="editor-label">
            @Html.LabelFor(model=>model.country, "Country")
        </div>
        <div class="editor-field">

Answer 1

View和控制器动作代码对我来说都很好看。问题将出在模型中的地址类中。 Mvc需要具有将webforms帖子反序列化的属性。

public string Country { get; set; }

您应该使用标题大小写为惯例，但如果将它们保持小写，它仍然可以使用。
