如何解决asp.net MVC 上传文件名为 System.Web.HttpPostedFileWrapper？

AdminBlog 是我的控制器名称。 博客是我数据库中的一个表。 Foto是表格中的一列。

当我保存表单时，Foto 列值变为 System.Web.HttpPostedFileWrapper。但是其他列的值正在获得正确的值。图像也没有上传到 BlogFoto 文件

这是我的型号代码：

public partial class Blog
{
    public int BlogID { get; set; }
    public string BlogBaslik { get; set; }

    [UIHint("tinymce_full")][AllowHtml]
    public string BlogIcerik { get; set; }
    public string Foto { get; set; }
    public Nullable<int> BlogokunmaSayisi { get; set; }
    public Nullable<int> BlogokunmaSuresi { get; set; }
    public Nullable<System.DateTime> BlogTarih { get; set; }
}

并查看代码：

@using (Html.BeginForm("Create","AdminBlog",FormMethod.Post,new { enctype = "multipart/form-data" }))
{
@Html.AntiForgeryToken()

<div>
    <h4>Yeni Blog Oluştur</h4>
    <hr />
    @Html.ValidationSummary(true,"",new { @})
    <div>
        @Html.LabelFor(model => model.BlogBaslik,htmlAttributes: new { @})
        <div>
            @Html.EditorFor(model => model.BlogBaslik,new { htmlAttributes = new { @} })
            @Html.ValidationMessageFor(model => model.BlogBaslik,new { @})
        </div>
    </div>

    <div>
        @Html.LabelFor(model => model.BlogIcerik,htmlAttributes: new { @})
        <div>
            @Html.EditorFor(model => model.BlogIcerik,new { htmlAttributes = new { @} })
            @Html.ValidationMessageFor(model => model.BlogIcerik,new { @})
        </div>
    </div>

    <div>
        @Html.LabelFor(model => model.Foto,htmlAttributes: new { @})
        <div>
            <input type="file" name="Foto"/>
            @Html.ValidationMessageFor(model => model.Foto,new { @})
        </div>
    </div>

 

    <div>
        @Html.LabelFor(model => model.BlogokunmaSuresi,htmlAttributes: new { @})
        <div>
            @Html.EditorFor(model => model.BlogokunmaSuresi,new { htmlAttributes = new { @,@placeholder = "DK cinsinden giriniz" } })
            @Html.ValidationMessageFor(model => model.BlogokunmaSuresi,new { @})
        </div>
    </div>

和控制器：

 [HttpPost]
    public ActionResult Create(Blog blog,HttpPostedFile Foto)
    {
        try
        {
            
            if (Foto != null)
            {
                
                WebImage webImage = new WebImage(Foto.InputStream);
                string newfoto = Path.GetFileNameWithoutExtension(Foto.FileName) + "-" + Guid.NewGuid() + Path.GetExtension(Foto.FileName);
               
                var filePath = "/Uploads/BlogFoto" + newfoto;

                webImage.Save(Server.MapPath(filePath));
                blog.Foto = filePath;

            }
            
           
            blog.BlogokunmaSayisi = 0;
            blog.BlogTarih = DateTime.Now;
            db.Blogs.Add(blog);
            db.SaveChanges();

            return RedirectToAction("Index");
        }
        catch
        {
            return View();
        }
    }

解决方法

public partial class Blog
{
   //...............................
   //...............................
   public HttpPostedFileBase FotoFile { get; set; }
}

<div>
  @Html.LabelFor(model => model.Foto,htmlAttributes: new { @})
  <div>
    <input type="file" name="Foto"/> 
    @Html.ValidationMessageFor(model => model.Foto,"",new { @})
  </div>
</div>

<div>
  @Html.LabelFor(model => model.FotoFile,htmlAttributes: new { @})
  <div>
    @Html.TextBoxFor(model => model.FotoFile,new { type = "file",@})
    @Html.ValidationMessageFor(model => model.FotoFile,null,new { @})
  </div>
</div>

[HttpPost]
public ActionResult Create(Blog blog)
{
      try
      {
         if (blog.FotoFile != null)
         { 
            WebImage webImage = new WebImage(blog.FotoFile.InputStream);
            string newfoto = Path.GetFileNameWithoutExtension(blog.FotoFile.FileName) + "-" + Guid.NewGuid() + Path.GetExtension(blog.FotoFile.FileName);
               
            var filePath = "/Uploads/BlogFoto" + newfoto;
            webImage.Save(Server.MapPath(filePath));
            blog.Foto = filePath;
     }
     //..................................................................
     //..................................................................
     }
     catch
     {
         return View();
     }
 }
