                  new { enctype = "multipart/form-data" }))
     {
   @Html.AntiForgeryToken()

   <div class="form-horizontal">

       @Html.ValidationSummary(true, "", new { @class = "text-danger" })
       @Html.HiddenFor(model => model.Id)

         <div class="form-group">
           @Html.LabelFor(model => model.Image, htmlAttributes: new { @class = "control-label col-md-2" })
           <div class="col-md-10">
             <img src="@Url.Content(Model.Image)" width="150" />
           </div>
       </div>
       }

What I have tried:

I want to delete the picture with the button. How can I do it ? I can delete products but I can not delete pictures. I can delete products with Id. I tried to do examples on the internet but I could not. Would you make an illustrative example?

Thanks in advance for help.

What do you mean by "picture"? What exactly do you want to delete?

Member 13582084 18-Dec-17 4:53am

I have a product, there are 6 pictures. I just want to remove the picture from the site.

Did you mean just use edit action to change product's image to empty and delete the file without delete product?

if that's the case you could define a hidden input to store delete action

@Html.Hidden("deleteImage","false")

and define button as Delete Image

use javascript to set hidden input to true

<script>
function DeleteImage(){
   $("#deleteImage").val('true');
   //todo:Set image src to empty
}
</script>

and then when you click post to the Edit Action

public ActionResult Edit(Product product, HttpPostedFileBase file,bool deleteImage)
    {
        if (ModelState.IsValid)
        {
           if(deleteImage){
                 //todo:delete image by product.Image
                 p.Image="";
            }
        }
    }

sir If you would like to delete from the folder where you save bellow is the code

var filePath = Server.MapPath("~/Images/" + filename);
if(File.Exists(filePath))
