ASP.NET MVC 实现页落网资源分享网站+充值管理+后台管理（10）之素材管理

素材管理模块也是我们这个项目的核心模块，里面的增删查改都跟文章管理模块相同或者相似，唯一不同点可能是对附件的上传处理，但没有涉及到复杂的文件上传，所以我们采用了原生的文件流的形式上传，同时在做了文件在编辑的时候，如果重新上传文件，我们将旧文件删除，这样可以释放更多的服务器空间，以免造成大量垃圾文件堆积。

在创建之前，我们需要在表现层的SystemExtension下创建一个公共类BaseCommon.cs：

同样的步骤，首先我们创建一个名为AttachmentMangeController的控制器、Index.cshtml视图，以及业务类Com_AttachmentBll.cs：
