HttpPostedFileBase retourne null à mon contrôleur

Question

gars Ho .Je essayer d'obtenir 3 photos de l'utilisateur donc mon modèle i quelque chose comme ceci:

namespace DomainClass 
{ 
    using System; 
    using System.Collections.Generic; 
    using System.Web.Http; 
    public partial class CompanyMember 
    { 
     public CompanyMember() 
     { 
      this.Proficiencies = new HashSet<Proficiency>(); 
     } 

     [DisplayName(" شناسه")] 
     public int Id { get; set; } 

     [DisplayName("عکس")] 
     public string ImageUrl { get; set; } 

     [DisplayName("کارت ملی")] 
     public string IntCartCopy { get; set; } 

     [DisplayName("شناسنامه")] 
     public string IdentityCartCopy { get; set; } 

       [System.ComponentModel.DataAnnotations.Schema.NotMapped] 
     public HttpPostedFileBase ImgFileImageUrl { get; set; } 
       [System.ComponentModel.DataAnnotations.Schema.NotMapped] 

     public HttpPostedFileBase ImgFileIntCartCopy { get; set; } 
       [System.ComponentModel.DataAnnotations.Schema.NotMapped] 

     public HttpPostedFileBase ImgFileIdentityCartCopy { get; set; } 


     public virtual Company Company { get; set; } 
     public virtual ICollection<Proficiency> Proficiencies { get; set; } 
    } 

donc à mon avis pour obtenir l'image que je crée 3 balises d'entrée comme celui-ci :

@model DomainClass.CompanyMember 

@{ 
    ViewBag.Title = "اضافه کردن اعضاء"; 
} 
@using (Html.BeginForm("Create", "CompanyMember", FormMethod.Post, 
    new { id = "form", enctype = "multipart/form-data" })) 
{ 
    @Html.ValidationSummary(true) 
    <div class="wrapper-left"> 
     <div class="wrapper-top-addCompany"> 
      اعضاء 
      <div style="float: left; padding-left: 20px;"> 
       <div class="divider"></div> 
       <div class="buttonPossion"> 
        <input type="submit" value="ذخیره اطلاعات" Class="buttonSave" /> 
        @Html.ActionLink("بازگشت", "index", new {companyId = ViewBag.companyId}, new {@class = "buttonBlueLink"}) 
       </div>

fichiers Publié sont disponibles dans

Request.Files 

Vous devriez les lire et enregistrer la db par l'action du contrôleur. Pour ce faire, utilisez le nom d'entrée en tant qu'index de la table Request.Files, par exemple:

HttpPostedFileBase img = Request.Files["ImgFileIntCartCopy"]; 
if(img != null) 
    img.SaveAs(path + img.FileName);
