HttpPost不MVC3工作

Question

當我用下面的代碼在控制器

[HttpPost] 
public ActionResult Index(HttpPostedFileBase file) 
{ 
    string path = Path.Combine(Server.MapPath("~/Images"), 
           Path.GetFileName(file.FileName)); 
    file.SaveAs(path); 

    ViewBag.Message = "File Uploaded Successfully"; 

    return View(); 
} 

當我運行我得到了以下錯誤

---Server Error in '/' Application. 
---The resource cannot be found. 

應用程序當我刪除[HttpPost]它加載，但文件沒有上傳...

任何人都可以幫助我嗎？......

Make sur e您正在創建如下形式，

@using (Html.BeginForm("Index", "Home", 
     FormMethod.Post,     
     new { enctype = "multipart/form-data" })) 
{ 
    <input type="file" name="file" /> 
    <input type="submit" value="OK" /> 
}
