Question

你能告诉我为什么没有上传文件，我只得到文件名吗？

我没有收到任何错误消息，所有信息都可以在DB中加载好吗？

我正在使用LINQ to SQL MVC4

表格ID - CompanyNameCon - PdfCon

控制器：

[HttpPost]
public ActionResult Create(DAT_SupplyCon DAT_SupplyCon, HttpPostedFileBase file)
{
    if (ModelState.IsValid)
    {

        DAT_SupplyCon.PdfCon = FileUpload.UploadFile(file);

        db.DAT_SupplyCons.InsertOnSubmit(DAT_SupplyCon);
        db.SubmitChanges();
        return RedirectToAction("Index");
    }

    return View(DAT_SupplyCon);
}

视图

@model CFire2.Models.DAT_SupplyCon

@{
ViewBag.Title = "Create";
}
<h2>Create</h2>

<script src="~/Scripts/jquery-1.8.2.min.js"></script>
<script src="~/Scripts/jquery.validate.min.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>



@using (Html.BeginForm("Create", "DAT_SupplyCons", FormMethod.Post, new { enctype          = "multipart/form-data" }))
{    
@Html.ValidationSummary(true)
<fieldset>
<legend>DAT_SupplyCon</legend>

<div class="editor-label">
    @Html.LabelFor(model => model.SupplierCon)
</div>
<div class="editor-field">
    @Html.EditorFor(model => model.SupplierCon)
    @Html.ValidationMessageFor(model => model.SupplierCon)
</div>

<div class="editor-label">
    @Html.LabelFor(model => model.CompanyNameCon)
</div>
<div class="editor-field">
    @Html.EditorFor(model => model.CompanyNameCon)
    @Html.ValidationMessageFor(model => model.CompanyNameCon)
</div>

<div class="editor-label">
@Html.LabelFor(model => model.PdfCon)

</div>
<div class="editor-field">
<input type="file" name="file" />
@Html.ValidationMessageFor(model => model.PdfCon)
</div>


<p>
    <input type="submit" value="Create" />
</p>
</fieldset>
}

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

的Utils：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IO;


namespace CFire2.Utils
{
public static class FileUpload
{

public static char DirSeparator =
System.IO.Path.DirectorySeparatorChar;
public static string FilesPath = "Content" +
DirSeparator + "Uploads" + DirSeparator;
public static string UploadFile(HttpPostedFileBase file)
{

   if (null == file) return "";

   if (!(file.ContentLength > 0)) return "";
   string fileName = file.FileName;
   string fileExt = Path.GetExtension(file.FileName);


   if (null == fileExt) return "";

   if (!Directory.Exists(FilesPath))
   {

      Directory.CreateDirectory(FilesPath);
   }

   string path = FilesPath + DirSeparator + fileName;

   file.SaveAs(Path.GetFullPath(path));

   return fileName;
}
public static void DeleteFile(string fileName)
{

   if (fileName.Length == 0) return;

   string path = FilesPath + DirSeparator + fileName;

   if (File.Exists(Path.GetFullPath(path)))
   {

       File.Delete(Path.GetFullPath(path));
   }
}
}
}

Answer 1

也许Server.MapPath是解决方案。例如：

var path = Path.Combine(HttpContext.Current.Server.MapPath("~/Content"), fileName);  
file.SaveAs(path);

你能告诉我为什么没有上传文件，我只得到文件名吗？
