我有一个上传表单,我想传递我的信息,如图片和其他一些字段,但我不知道如何上传图片..
这是我的控制器代码:
[HttpPost]
public ActionResult Create(tblPortfolio tblportfolio)
{
if (ModelState.IsValid)
{
db.tblPortfolios.AddObject(tblportfolio);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(tblportfolio);
}
这是我的观看代码:
@model MyApp.Models.tblPortfolio
<h2>Create</h2>
@using (Html.BeginForm(null, null, FormMethod.Post, new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
<legend>tblPortfolio</legend>
<div class="editor-label">
@Html.LabelFor(model => model.Title)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Title)
@Html.ValidationMessageFor(model => model.Title)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.ImageFile)
</div>
<div class="editor-field">
@Html.TextBoxFor(model => model.ImageFile, new { type = "file" })
@Html.ValidationMessageFor(model => model.ImageFile)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Link)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Link)
@Html.ValidationMessageFor(model => model.Link)
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}
现在我不知道如何上传图像并将其保存在服务器上..如何通过Guid.NewGuid();
设置图像名称?或者我该如何设置图像路径?

首先,您需要更改视图以包含以下内容:
<input type="file" name="file" />
然后,您需要更改帖子ActionMethod
以获取HttpPostedFileBase
,如下所示:
[HttpPost]
public ActionResult Create(tblPortfolio tblportfolio, HttpPostedFileBase file)
{
//you can put your existing save code here
if (file != null && file.ContentLength > 0)
{
//do whatever you want with the file
}
}

您可以使用Request
收集从Request.Files
获取,如果是单个文件上传,只需使用Request.Files[0]
从第一个索引中读取:
[HttpPost]
public ActionResult Create(tblPortfolio tblportfolio)
{
if(Request.Files.Count > 0)
{
HttpPostedFileBase file = Request.Files[0];
if (file != null)
{
// business logic here
}
}
}
如果要上传多个文件,则必须迭代Request.Files
集合:
[HttpPost]
public ActionResult Create(tblPortfolio tblportfolio)
{
for(int i=0; i < Request.Files.Count; i++)
{
HttpPostedFileBase file = Request.Files[i];
if (file != null)
{
// Do something here
}
}
}
如果您想通过ajax上传没有页面刷新的文件,那么您可以使用this article which uses jquery plugin
