我正在尝试创建一个创建模型对象页面。我正在使用 asp.net mvc 和 c#。在我的项目中,我正在尝试创建一个有书籍的图书馆应用程序,我们可以从有图片的应用程序添加书籍。所以我的创建控制器是这样的,

 [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();
        }
    }

我的观点是这样的,

   {%>
    <%: Html.ValidationSummary(true) %>
    <fieldset>
        <legend>Fields</legend>
        <div class="editor-label">
            <%: Html.LabelFor(model => model.name) %>
        </div>
        <div class="editor-field">
            <%: Html.TextBoxFor(model => model.name) %>
            <%: Html.ValidationMessageFor(model => model.name) %>
        </div>
        <div class="editor-label">
            <%: Html.LabelFor(model => model.author) %>
        </div>
        <div class="editor-field">
            <%: Html.TextBoxFor(model => model.author) %>
            <%: Html.ValidationMessageFor(model => model.author) %>
        </div>
        <div class="editor-label">
            <%: Html.LabelFor(model => model.picture) %>
        </div>
        <div class="editor-field">
            <%: Html.TextBoxFor(model => model.picture) %>
            <%: Html.ValidationMessageFor(model => model.picture) %>
        </div>
        <input type='file' name='picture1' id='picture1' />
        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
<% } %>
<div>
    <%: Html.ActionLink("Back to List", "Index") %>
</div>

我尝试了很多东西,但我无法上传任何文件。我能做什么?

无法 ASP.NET MVC 上传文件

尝试从Request获取已发布的文件。

var picture1 = this.Request.Files["picture1"];

在你的书模型中应该是一个preperty

HttpPostedFileBase picture1
