带有文件类型和文本的表单上的 C# asp.net 问题

Question

我要开门见山了，

我有一个表格。当我保存表格时......它只得到名字，中间名和姓氏......它没有得到文件......但是，如果我只得到照片并注释掉其他输入......照片是在我的模型..我不知道为什么它会这样..我真的是asp.net mvc的新手..所以请耐心等待..

@model Impulse.ViewModels.AgentViewModel

@{
    ViewBag.Title = "AgentForm";
    Layout = "~/Views/Shared/_SiteLayout.cshtml";
}

<div class="custom-container">
    <h1 class="title"><strong>Add New Agent</strong></h1>
    <hr />
   @using (Html.BeginForm("Save", "Agent", FormMethod.Post, new { enctype = "multipart/form-data" }))
   {

    <div class="row">
        <div class="col-md-3">
            <div id="preview">

            </div>
            <div class="form-group">

        </div>
    </div>


    <input type="submit" class="btn btn-primary" value="Save" />
   }


</div>

Controller

   [HttpPost]
    public ActionResult Save(AgentModel agent)
    {
        //I debug here to see the data passed by my view
        return Content("Sample");
    }

型号

public class AgentModel
{
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string MiddleName { get; set; }
        [FileSize(10240)]
        [FileTypes("jpg,jpeg,png")]
        public HttpPostedFileBase photo { get; set; }

    }

你可以这样试试

型号

public class UploadFileModel 
{
    public UploadFileModel()
    {
        Files = new List<HttpPostedFileBase>();
    }

    public List<HttpPostedFileBase> Files { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string MiddleName { get; set; }
}

查看

@using (Html.BeginForm("UploadData", "Home", FormMethod.Post, new { encType="multipart/form-data" }))
{
    @Html.TextBoxFor(m => m.FirstName)
    <br /><br />

    @Html.TextBoxFor(m => m.Files, new { type = "file", name = "Files" })<br /><br />
    <input type="submit" value="submit" name="submit" id="submit" />
}

Controller

public ActionResult UploadData(UploadFileModel model)
{
    var file = model.Files[0];
    return View(model);
}
