asp.net-mvc – 在bootstrap模式中使用时,MVC中的文件上载返回nu

模型

[Table("Slider")]
public partial class Slider : BaseModel
{
    [Required]
    [StringLength(200)]
    public string FileName { get; set; }

    [StringLength(200)]
    public string Title { get; set; }

    [StringLength(1000)]
    public string Description { get; set; }

    public int? Order { get; set; }
}


[NotMapped]
public class SliderImage : Slider
{
    public HttpPostedFileBase ImageFile { get; set; }
}

视图

@using (Html.BeginForm(null,null,FormMethod.Post,new { enctype = "multipart/form-data" }))
{
@Html.AntiForgeryToken()
<div class="modal-body">
    <div class="form-horizontal">
        @Html.ValidationSummary(true,"",new { @class = "text-danger" })
        @Html.HiddenFor(model => model.Id)

        <div class="form-group">
            @Html.LabelFor(model => model.FileName,new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.TextBoxFor(model => model.FileName,new { @class = "form-control",@readonly = "readonly" })
                @Html.ValidationMessageFor(model => model.FileName,new { @class = "text-danger" })
            </div>
        </div>
        <div class="form-group">
            @Html.LabelFor(model => model.ImageFile,new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.TextBoxFor(m => m.ImageFile,type = "file" })
               //This is Same as below
               //<input class="form-control" id="ImageFile" name="ImageFile" type="file" value="">
            </div>
        </div>

调节器

public ActionResult Edit(int id)
    {
        Slider slider = _db.Sliders.Find(id);
        if (slider == null)
        {
            return HttpNotFound();
        }
        Mapper.CreateMap<Slider,SliderImage>();
        SliderImage sliderImage = Mapper.Map<Slider,SliderImage>(slider);
        return PartialView("_Edit",sliderImage);
    }


    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult EditSlider([Bind(Include = "Id,FileName,Title,Description,Order,IsActive,Name,ImageFile")] SliderImage sliderImage)
    {
        if (ModelState.IsValid)
        {
            Mapper.CreateMap<SliderImage,Slider>();
            Slider slider = Mapper.Map<SliderImage,Slider>(sliderImage);
            _db.Entry(slider).State = EntityState.Modified;
            _db.SaveChanges();
            return Json(new { success = true });
        }
        return PartialView("_EditSlider");
    }

我这么做错了什么？

找到了问题

我绑定了bootstrap模式弹出窗口内的局部视图.当我从弹出窗口上传时,上传返回null.相反,如果我直接在浏览器中打开部分View,那么该文件将出现在模型中.所以文件上传没有问题.问题出在模态弹出窗口或其他东西上.

使用Bootstrap模型时

使用部分View Directy时

检查在下面的图像中分别使用引导程序模态提交和直接使用部分查看时使用fiddler时发现的差异

从模态弹出窗口发布时,内容类型更改为application / x-www-form-urlencoded,直接使用局部视图时,它是multipart / form-data

找到根问题.

$('form',dialog).submit(function () {
                    var $form = $(this);
                    var enctype = $form.attr('id');
                    $.ajax({
                        url: this.action,type: this.method,data: $(this).serialize(),success: function (result) {
                            if (result.success) {
                                $('#myModal').modal('hide');
                                //Refresh
                                location.reload();
                            } else {
                                $('#myModalContent').html(result);
                                bindForm();
                            }
                        }
                    });
                    return false;
                });

我正在使用AJAX发布来提交表单中的数据.当使用$(this).serialize()时,正在调用ajax成功,但由于内容类型不同,文件未返回.我该怎么改变？
