我想让用户上传图片到我们的网站,我不太确定如何使用它。我试图使用多种类型来定义图像,包括System.Drawing.Image
和HttpPostedFileWrapper
,但@Html.EditorFor
始终(可以理解)将其属性作为要编辑的字段。@ Html.EditorFor(Image)
在我看来,我确实有,而不是@Html.EditorFor
我确实有<input type="file" name="imageToUpload" />
,但它没有通过我的观点作为Model
的一部分?我对MVC相当陌生,所以我希望这是件小事。
这是我的观点:
@using (Html.BeginForm()) {
@Html.ValidationSummary(true)
<fieldset>
<legend>New Image</legend>
<div class="editor-label">
@Html.LabelFor(model => model.Description)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Description)
@Html.ValidationMessageFor(model => model.Description)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Image)
</div>
<div class="editor-field">
<input type="file" name="imageToUpload" />
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}
我的控制器:
[HttpPost]
public ActionResult CreateImage(string brand, string collection, ImageEditViewModel imageEditViewModel)
{
string fileName = Guid.NewGuid().ToString();
string serverPath = Server.MapPath("~");
string imagesPath = serverPath + String.Format("Content\\{0}\\Images\\", Helper.Helper.ResolveBrand());
string newLocation = Helper.Helper.SaveImage(fileName, imagesPath, imageEditViewModel.Image.InputStream)
Image image = new Image
{
Collection = ds.Single<Collection>(c => c.Season == collection
&& c.Brand.Name == brand),
Description = imageEditViewModel.Description,
Location = "newLocation",
Order = Helper.Helper.GetImageOrder(brand, collection)
};
ds.InsertOnSubmit<Image>(image);
ds.SubmitChanges();
return RedirectToAction("Brand");
}
最后视图模型:
public class ImageEditViewModel
{
public int CollectionId { get; set; }
public string Description { get; set; }
public HttpPostedFileWrapper Image { get; set; }
public int Order { get; set; }
}
a +1,enctype很容易就是最常被遗忘的东西之一。 – 2012-03-13 10:21:59
不通过CreateResult仍然通过.. – ediblecode 2012-03-13 10:24:12
是刚刚在视图中看到我把它命名为imageToUpload,但应该是图像。谢谢一堆 – ediblecode 2012-03-13 10:28:59
