Question

我有一个强类型视图，可以创建如下的表单字段：

@Html.TextBoxFor(x => x.Name, new { @class = "form-control" })

很好，上面的lambda表达式中的X与我使用＆＃39; Name＆＃39;的属性创建的I类相关。

如何使用相同的视图但是可以访问其他类的属性？例如，如果您想象我还有另一个名为UserDetails的类，并且电子邮件地址是其中的一个属性。我该怎么做：

@Html.TextBoxFor(x => x.Email, new { @class = "form-control" })

在同一个强类型视图中？

在asp.net mvc中，你将模型传递给这样的视图：

    public ActionResult Base()
        {
            return View(new DerviedOne());
        }

以下是您的模型定义：

  public class BaseModel
    {
        public int Id { get; set; }
    }

    public class DerviedOne : BaseModel
    {
        public string Email { get; set; }
    }

    public class DerviedTwo : BaseModel
    {
        public string Name { get; set; }
    }

然后你必须创建三个视图：

基本视图：

@using Models
@model Models.BaseModel

@{
    ViewBag.Title = "Base";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Base</h2>

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

    <div class="form-horizontal">
        <h4>BaseModel</h4>
        <hr/>
        @Html.ValidationSummary(true, "", new {@class = "text-danger"})
        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                @Html.TextBoxFor(x=>x.Id)
                <input type="submit" value="Create" class="btn btn-default"/>
            </div>
        </div>
    </div>

    if(Model is DerviedOne)
     {
         Html.RenderPartial("DerviedOneView", Model as DerviedOne);
     }

    if (Model is DerviedTwo)
    {
        Html.RenderPartial("DerviedTwoView", Model as DerviedTwo);
    }
}

第二种观点：

@model WebApplication.Models.DerviedOne

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

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

第三种观点：

@model WebApplication.Models.DerviedTwo

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

    <div class="form-horizontal">
        <h4>DerviedTwo</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">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Create" class="btn btn-default" />
            </div>
        </div>
    </div>
}
