c# - MVC父子模态文件上传问题
问题描述
我有一个用于获取标题详细数据的父子场景。这是我的代码，问题是当我使用文件上传时它不起作用
Person模型：
public class Person
{
[Key, DatabaseGenerated(DatabaseGeneratedOption.None)]
public int Id { get; set; }
[Display(Name = "First Name")]
[Required]
[StringLength(255, MinimumLength = 3)]
public string Name { get; set; }
[Display(Name = "Last Name")]
[Required]
[StringLength(255, MinimumLength = 3)]
public string Surname { get; set; }
public virtual ICollection<Address> Addresses { get; set; }
[Required(AllowEmptyStrings = false, ErrorMessage = "Error: Must Choose a Country")]
[Range(1, int.MaxValue, ErrorMessage = "Select a Country")]
public int CountryID { get; set; }
public virtual Country Country { get; set; }
}
Address模型：
public class Address
{
[Key, DatabaseGenerated(DatabaseGeneratedOption.None)]
public int Id { get; set; }
[Required(AllowEmptyStrings = false, ErrorMessage = "Error: Must Choose a City")]
[Range(1, int.MaxValue, ErrorMessage = "Select a City")]
public int CityID { get; set; }
public virtual City City { get; set; }
[Required]
[Display(Name = "Street Address")]
public string Street { get; set; }
[Required]
[DataType(DataType.ImageUrl)]
public string ImageUrl { get; set; }
[NotMapped]
[DataType(DataType.Upload)]
public HttpPostedFileBase ImageUpload { get; set; }
[Required]
[Phone]
public string Phone { get; set; }
public int PersonID { get; set; }
public virtual Person Person { get; set; }
}
PeopleController：
private DataDb db = new DataDb();
// GET: People
public async Task<ActionResult> Index()
{
return View(await db.People.ToListAsync());
}
// GET: People/Details/5
public async Task<ActionResult> Details(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
Person person = await db.People.Where(p => p.Id == id).Include(p => p.Addresses).SingleAsync();
if (person == null)
{
return HttpNotFound();
}
return View(person);
}
// GET: People/Edit/5
public async Task<ActionResult> Edit(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
var person = await db.People
.Include(p => p.Addresses)
.Where(p => p.Id == id)
.SingleAsync();

{
return HttpNotFound();
}
ViewBag.CountryID = new SelectList(db.Country, "CountryID", "CountryName", person.CountryID);
return View(person);
}
// POST: People/Edit/5

Address控制器：
