在零配置狀況下，文件的上傳文件夾是根目錄下的Files文件夾，如何自定義文件的上傳文件夾呢？css

□ 在web.config中配置git

   1:  <configuration>

   2:    <configSections>

   3:    ...

   4:    <section name="backload" type="Backload.Configuration.BackloadSection, Backload, Version=1.9.3.1, Culture=neutral, PublicKeyToken=02eaf42ab375d363" requirePermission="false" />

   5:    </configSections>

6:

   7:     <backload xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:name="urn:fileupload-schema" xsi:noNamespaceSchemaLocation="Web.FileUpload.xsd">

   8:      <fileSystem filesRoot="~/Uploads" />

   9:    </backload>

10:

  11:  </configuration>

Version能夠經過右鍵程序集屬性中查到。github

PublicKeyToken能夠經過反編譯器，好比Reflector查到。web

□ 註銷BackloadDemoController的Index方法bootstrap

   1:  using System.Web.Mvc;

2:

   3:  namespace MvcApplication6.Controllers

   4:  {

   5:      public class BackloadDemoController : Controller

   6:      {

   7:          // GET: /BackupDemo/

   8:          //public ActionResult Index()

   9:          //{

  10:          //    return View();

  11:          //}

  12:      }

  13:  }

□ 讓BaseController繼承BackloadDemoController，並註銷Index方法異步

   1:  using System.Web.Mvc;

2:

   3:  namespace MvcApplication6.Controllers

   4:  {

   5:      public class BaseController : BackloadDemoController

   6:      {

   7:          //public ActionResult Index()

   8:          //{

   9:          //    return View();

  10:          //}

  11:      }

  12:  }

□ 讓HomeController繼承BaseControllerui

   1:  using System.Web.Mvc;

2:

   3:  namespace MvcApplication6.Controllers

   4:  {

   5:      public class HomeController : BaseController

   6:      {

   7:          public ActionResult Index()

   8:          {

   9:              return View();

  10:          }

  11:      }

@section scripts
{
    <script src="~/Scripts/FileUpload/backload.demo.js"></script>
}

□ 結果：

上傳2個文件：

此次，圖片上傳到了Uploads文件夾：

Uploads文件夾有剛上傳的2個文件：

□ 若是想讓web.config配置文件相對「乾淨」，能夠把與Backload相關的配置放到單獨的一個配置文件

web.config中能夠這樣：

   1:  <configuration>

   2:    <configSections>

   3:    ...

   4:    <section name="backload" type="Backload.Configuration.BackloadSection, Backload, Version=1.9.3.1, Culture=neutral, PublicKeyToken=02eaf42ab375d363" requirePermission="false" />

   5:    </configSections>

6:

   7:     <backload configSource="Web.Backload.config" />

   8:  </configuration>

根目錄下的Web.Backload.config能夠這樣：

   1:  <?xml version="1.0"?>

   2:  <backload storageContext="Filesystem" xsi:noNamespaceSchemaLocation="Web.Backload.xsd" xmlns:name="urn:backload-schema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

   3:    <fileSystem filesRoot="~/Uploads" />

   4:  </backload>
