我正在嘗試創建一個創建模型對象頁面。我用C#使用asp.net mvc。在我的項目中,我試圖創建一個圖書館應用程序,它有圖書,我們可以從應用程序中添加圖書。所以我創建這樣的控制器,無法上傳文件ASP.NET MVC
[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();
}
}
和我的看法是這樣的,
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<MvcApplication2.Models.Book>" %>

<fieldset>
<legend>Fields</legend>
<div class="editor-label">

</div>
<div class="editor-field">

</div>
<div class="editor-label">

</div>
<div class="editor-field">

<%: 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>
我已經嘗試了很多事情,但我不能上傳任何文件。我能做什麼?
是什麼問題?是'picture1' null? –
