我的看法是这样的,

 [HttpPost]
    public ActionResult Create([Bind(Exclude = "id,bringBack,borrower,isBorrowed")]Book bookToCreate, HttpPostedFileBase picture1)
    {
        try
        {
            if (picture1.ContentLength > 0)
            {
                var fileName = Path.GetFileName(picture1.FileName);
                var path = Path.Combine(Server.MapPath("~/App_Data/pictures"), fileName);
                picture1.SaveAs(path);
            }

            // TODO: Add insert logic here
            _entities.AddToLibrary(bookToCreate);
            _entities.SaveChanges();

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

我尝试了很多东西，但我无法上传任何文件。我能做什么？

尝试从

请求中获取已发布的文件
var picture1 = this.Request.Files["picture1"];

在你的书中，模特应该是一个预科生
HttpPostedFileBase picture1

有什么问题？picture1
null吗？现在我可以获取文件了，我更改了BeginForm的参数。但我无法保存文件。我能为此做些什么？如何更改文件权限？@Daniel A White，然后提供更好的答案，而不仅仅是批评。@Ömer Faruk AK-您需要更改要保存文件的路径的权限。
