HttpPostedFileBase返回null到我的控制器
本文关键字：我的 控制器 null 返回 HttpPostedFileBase | 更新日期: 2023-09-27 18:08:37
各位，我试着从用户那里得到3张照片，所以我的模型是这样的:
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; }
}
所以在我看来，为了获得图片，我创建了3个输入标签，像这样:
@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%">

@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}
但提交3 HttpPostedFileBase列返回null在我的控制器我检查了文件的值，所有它们都是null为什么?我的if条件返回false
public ActionResult Create(CompanyMember companyMember)
{
if (companyMember.ImgFileImageUrl != null && companyMember.ImgFileIntCartCopy!=null && companyMember.ImgFileIdentityCartCopy!=null)
{
saving
}
}
张贴的文件可在
Request.Files
您应该读取它们并通过控制器动作保存到db。为此，使用输入的名称作为Request。文件表索引，例如:
HttpPostedFileBase img = Request.Files["ImgFileIntCartCopy"];
if(img != null)
img.SaveAs(path + img.FileName);
