Generate file upload input for property with “DataType.Upload” attribute?

Question

I have the following view model.

public class MyViewModel
{
    [DataType(DataType.Upload)]
    public HttpPostedFileBase ImageUpload { get; set; }

    publ         


        

Answer 1

I have another idea. How about getting rid of the HttpPostedFileBase from the model and from the controller either ?

In your html, you would add:

 @using (Html.BeginForm("actionNameYouWriteToManupulate", "controllerYouWrite", FormMethod.Post, new { enctype = "multipart/form-data" }))
 {
   
   
   ...
   
 }

Add Files as many files you want, and in the controller :

var hfc = Request.Files;
for (int i = 0; i < hfc.Count; i++)
            {
                var hpf = hfc[i];
                if (hpf.ContentLength > 0)
                {
                   //Do what you want with files 
                   //Handler pointed to file is hpf for example :
                   hpf.SaveAs(Server.MapPath(fullPathWithFileName));
                 }
            }

Hope to be usefull.
