html.editorfor 文件,c# - @Html.EditorFor (Image) - Stack Overflow-爱代码爱编程 Posted on2021-06-18 分类: html.editorf

I am trying to allow a user to upload an image to our website and I'm not quite sure about how to use this. I have tried to use multiple types to define the image, including System.Drawing.Image and HttpPostedFileWrapper but the @Html.EditorFor always (understandably) brings up its attributes as fields to edit.

In my view I did have, instead of @Html.EditorFor I did have but it didn't get taken through to my view as part of the Model? I am quite new to MVC so I am hoping it is something trivial.

Here is my View:

@using (Html.BeginForm()) {

@Html.ValidationSummary(true)

New Image

@Html.LabelFor(model => model.Description)

@Html.EditorFor(model => model.Description)

@Html.ValidationMessageFor(model => model.Description)

@Html.LabelFor(model => model.Image)

}

My Controller:

[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(c => c.Season == collection

&& c.Brand.Name == brand),

Description = imageEditViewModel.Description,

Location = "newLocation",

Order = Helper.Helper.GetImageOrder(brand, collection)

};

ds.InsertOnSubmit(image);

ds.SubmitChanges();

return RedirectToAction("Brand");

}

And finally the ViewModel:

public class ImageEditViewModel

{

public int CollectionId { get; set; }

public string Description { get; set; }

public HttpPostedFileWrapper Image { get; set; }

public int Order { get; set; }

}
