HttpPostedFileBase返回null我控制器

Question

何人。我試圖從用戶拍攝3張照片，所以我的模型，我是這樣的：

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; } 
    } 

所以，在我看來，要得到的圖片我創造這樣的3個輸入標籤：

@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> 
       <div class="divider"></div> 
      </div> 
     </div> 
          @Html.HiddenFor(model => model.CompanyId) 

     <div class="wrapper"> 
      <div class="wrapper-Member" style="padding-bottom: 30px; margin-bottom: 5px; width: 98%"> 
       <h2>

       <div class="editor-field">

        <input id="imgProfile" type="file" name="ImgFileImageUrl"/>

       <div class="editor-label">

       <div class="editor-label">

        <input id="imgIdentityCartCopy" type="file" name="ImgFileIdentityCartCopy"/> 
       </div> 

      </div> 
     </div> 
    </div> 
} 

<div> 
    @Html.ActionLink("Back to List", "Index") 
</div> 

@section Scripts { 
    @Scripts.Render("~/bundles/jqueryval") 
} 

但提交3個HttpPostedFileBase colums後返回null。在我控制我檢查文件的價值，所有的人都爲空，爲什麼和我如果條件返回假

？

public ActionResult Create(CompanyMember companyMember) 
     { 
      if (companyMember.ImgFileImageUrl != null && companyMember.ImgFileIntCartCopy!=null && companyMember.ImgFileIdentityCartCopy!=null) 
      { 

       saving 
      } 

     }

發佈文件

Request.Files 

可用你應該閱讀並通過控制器動作保存到數據庫。爲此，請使用輸入的名稱作爲Request.Files表索引，例如：

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