我正在开发一个依赖现有SQL Server数据库的应用程序。我已经在Visual Studio中使用实体框架代码优先方法创建了模型，控制器和创建视图。目前，该代码适用于所有字段，并且接受null表示应包含外部文件路径的字段（不在DB中）。
模型：
namespace Centurion.Models
{
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Data.Entity.Spatial;
[Table("Fontane")]
public partial class Fontane
{
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
public Fontane()
{
Interventi = new HashSet<Interventi>();
}
[Key]
//[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int FontanaID { get; set; }
private string _CodificaSIMU;
[StringLength(20)]
public string CodificaSIMU
{
get
{
if (string.IsNullOrEmpty(_CodificaSIMU))
{
return _CodificaSIMU;
}
return _CodificaSIMU.ToUpper();
}
set
{
_CodificaSIMU = value;
}
}
//public string CodificaSIMU { get; set; }
[Required]
[StringLength(255)]
public string Nome { get; set; }
[StringLength(255)]
public string Indirizzo { get; set; }
public int? Municipio { get; set; }
[Required]
public double Latitudine { get; set; }
[Required]
public double Longitudine { get; set; }
[Required]
public int TipoFontana { get; set; }
[Required]
public int TipoImpianto { get; set; }
[Required]
public int Frequenza { get; set; }
[Required]
public bool Svuotamento { get; set; }
public bool? Active { get; set; }
public bool? Allarme { get; set; }
[StringLength(255)]
public string Foto { get; set; }
[StringLength(255)]
public string Allegato1 { get; set; }
[StringLength(255)]
public string Allegato2 { get; set; }
public string Note { get; set; }
[Required]
public int UserIDCrea { get; set; }
[Required]
public DateTime DataCrea { get; set; }
[Required]
public int UserIDModifica { get; set; }
[Required]
public DateTime DataModifica { get; set; }
public virtual Municipi Municipi { get; set; }
public virtual TipiFontana TipiFontana { get; set; }
public virtual Impianto Impianto { get; set; }
public virtual Utenti Utenti { get; set; }
public virtual Utenti Utenti1 { get; set; }
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
public virtual ICollection<Interventi> Interventi { get; set; }
}
public class FontaneFiles
{
[DataType(DataType.Upload)]
[Display(Name = "Upload Foto")]
public string FotoFile { get; set; }
[DataType(DataType.Upload)]
[Display(Name = "Upload Allegato1")]
public string All1File { get; set; }
[DataType(DataType.Upload)]
[Display(Name = "Upload Allegato2")]
public string All2File { get; set; }
}
}
您可以看到，由于数据库中的相对表仅包含服务器中路径的字符串，因此我添加了第二个类来上传文件。
这是我的控制器的代码，除了文件上传部分外，它的工作正常：
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Crea([Bind(Include = "FontanaID,CodificaSIMU,Nome,Indirizzo,Municipio,Latitudine,Longitudine,TipoFontana,TipoImpianto,Frequenza,Svuotamento,Foto,Allegato1,Allegato2,Note")] Fontane fontane)
//public ActionResult Crea([Bind(Include = "FontanaID,CodificaSIMU,Nome,Indirizzo,Municipio,Latitudine,Longitudine,TipoFontana,TipoImpianto,Frequenza,Svuotamento,Active,Allarme,Foto,Allegato1,Allegato2,Note,UserIDCrea,DataCrea,UserIDModifica,DataModifica")] Fontane fontane)
{
// to be replaced in production mode with logged user
fontane.UserIDCrea = cUser;
fontane.UserIDModifica = cUser;
// set date as NOW
fontane.DataCrea = DateTime.Now;
fontane.DataModifica = DateTime.Now;
// no allarm when creating
fontane.Allarme = false;
// active when creating
fontane.Active = true;
fontane.Latitudine = Convert.ToDouble(fontane.Latitudine);
fontane.Longitudine = Convert.ToDouble(fontane.Longitudine);
if (ModelState.IsValid)
{
try
{
db.Fontane.Add(fontane);
db.SaveChanges();
return RedirectToAction("Indice");
}
catch (DbUpdateException)
{
ModelState.AddModelError(string.Empty, "Fontana esistente!");
}
catch (Exception ex)
{
return View("Error", new HandleErrorInfo(ex, "Fontane", "Crea"));
}
return View();
}
ViewBag.TipoImpianto = new SelectList(db.Impianto, "ImpiantoID", "Impianto1", fontane.TipoImpianto);
ViewBag.Municipio = new SelectList(db.Municipi, "MunicipioID", "Municipio", fontane.Municipio);
ViewBag.TipoFontana = new SelectList(db.TipiFontana, "TipoID", "Descrizione", fontane.TipoFontana);
ViewBag.UserIDCrea = new SelectList(db.Utenti, "UserID", "UserName", fontane.UserIDCrea);
ViewBag.UserIDModifica = new SelectList(db.Utenti, "UserID", "UserName", fontane.UserIDModifica);
return View(fontane);
}
视图：
@model Centurion.Models.Fontane
@{
ViewBag.Title = "Crea";
}

我无法更改数据库表，但是我需要找到一种触发图像和其他文件（应为pdf或Excel）上传的方法。文件将存储在app_data文件夹的子文件夹中。
如果将文件添加到Fontane的同一类中，则会出现表错误。我试图将两个类与一个元组结合在一起，但是我不知道如何在Controller中管理它们。任何帮助将不胜感激。
