CS1061:'IEnumerable <>'不包含''且没有扩展方法'的定义''接受'IEnumerable <>'类型的第一个参数

Question

我是.net MVC的新手.请帮我解决我的问题.

我收到此错误:CS1061:'IEnumerable'不包含'Name'的定义,并且没有扩展方法'Name'可以找到接受'IEnumerable'类型的第一个参数.

这是我的控制器public ActionResult Create(){return Index(); }

    [HttpPost]
    public ActionResult Create(Person model)
    {
        HttpClient client = new HttpClient();
        client.BaseAddress = new Uri("http://localhost:23793");

        client.PostAsJsonAsync<Person>("api/person", model)
            .ContinueWith((postTask) => postTask.Result.EnsureSuccessStatusCode());

        return RedirectToAction("Index");
    }

在这里我的观点

           @model IEnumerable<PersonDemoMVC.Models.Person>

        @{
            ViewBag.Title = "Create";
        }

        <h2>Create</h2>


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

            <div class="form-horizontal">
                <h4>Person</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.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", "Index")
        </div>

        <script src="~/Scripts/jquery-1.10.2.min.js"></script>
        <script src="~/Scripts/jquery.validate.min.js"></script>
        <script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>

您的Create视图强类型为Personentity(IEnumerable<Person>)的集合,并且在您的视图中,您正在执行代码Model.Name(如Html帮助程序方法中的model => model.Name).这里的模型是一个IEnumerable<Person>和IEnumerable没有Name属性!

在创建视图中使用单个Person实例作为模型,而不是使用集合.

@model PersonDemoMVC.Models.Person
<h2>Create</h2>
@using(Html.BeginForm())
{
   @Html.TextBoxFor(s=>s.Name)
   <!-- Your existing form elements -->
   <input type="submit" />
}
