Question

我有一个ViewModel，里面有两个模型，可以在显示数据时查找。我的问题是我想在Create.cshtml文件中添加foreach（）。有什么想法吗？

---- Create.cshml -----

@model demo.Models.ViewModel

@{ ViewBag.Title = "Create Reference";}<h2>Create</h2>
@using (Html.BeginForm()) {    
@Html.AntiForgeryToken()    
@Html.ValidationSummary(true)    
<fieldset>
        <legend>Submission Form </legend>        

    <div class="editor-label">
        @Html.LabelFor(model => model.Name)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Name)
        @Html.ValidationMessageFor(model => model.Name)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.Title)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Title)
        @Html.ValidationMessageFor(model => model.Title)
    </div> 

                 <div class="editor-field">
                     <!-- iterate through ExternalContentModel and make checkboxes. -->
                    @foreach (var item in Model.ExternalContentModel)
                    {
                        <label class="checkbox">
                             <input type="checkbox" name="users" value="@item.auth_lname"> @item.auth_lname
                        </label>
                    }
                </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.OrganizationName)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.OrganizationName)
        @Html.ValidationMessageFor(model => model.OrganizationName)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.Address)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Address)
        @Html.ValidationMessageFor(model => model.Address)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.City)
    </div>      

    <p>
        <input type="submit" value="Create" />
    </p>
</fieldset>

}

如果您有不同的型号，为什么不为每个型号创建一个编辑器模板？

您可以通过创建一个名为＆＃34; EditorTemplates＆＃34;的文件夹来完成此操作。在您的Create.cshtml视图所在的同一文件夹中。现在将模型的视图添加到该文件夹中。视图的名称应与模型类相同。例如。一个名为FooBarModel的类将有一个名为FooBarModel.cshtml的编辑器模板。

然后你可以通过@Html.EditorFor（x =＆gt; x.FooBar）来使用编辑器模板

将viewmodel与create视图一起使用
