【MVC】MVC上傳圖片

1. View ```csharp
   @using (Html.BeginForm(“edit”, “group”, FormMethod.Post, new { enctype = “multipart/form-data” }))
   {
   圖片
   }

2.  Controller，這邊特別注意<span style="color: blue;">HttpPostedFileBase</span> picture的參數名稱要與View file的name相同 ```csharp
public ActionResult AddExhibitionItem(string name, string sort,string stop ,HttpPostedFileBase picture)
{
   string err= string.Empty;
   if (ExhibitionUtilFactory.AddItem(name, sort, stop, picture, ref err))
   {
     return Content("<script>alert('新增成功');window.parent.closeDialog();</script>");
   }
   else   {
      TempData["alert"] = err;
      return View();
   }
}

3. 如果是多檔上傳的話，View ```csharp
   圖片

4.  Controller ```csharp
public ActionResult AddExhibitionItem(string name, string sort,string stop ,IEnumerable<HttpPostedFileBase> picture)
{
   foreach (var file in picture)   {
     ............   }
}
