最近参考网络资料，学习了ASP.NET MVC如何上传文件。最基本的，没有用jQuery等技术。

1、定义Model

    public class TestModel

    {

        [Display(Name = "标题")]

        [Required]

        public string Title

        {

            get;

            set;

        }

        [Display(Name = "内容")]

        [Required]

        [DataType(DataType.MultilineText)]

        public string Content

        {

            get;

            set;

        }

        public string AttachmentPath

        {

            get;

            set;

        }

    }

2、Controller

public class TestController : Controller    {        //        // GET: /Test/        public ActionResult Upload()        {            return View();        }        /// 
        /// 提交方法        /// 
        /// 模型数据        /// 上传的文件对象，此处的参数名称要与View中的上传标签名称相同        /// 
             [HttpPost]        public ActionResult Upload(TestModel tm, HttpPostedFileBase file)        {            if (file == null)            {                return Content("没有文件！", "text/plain");            }            var fileName = Path.Combine(Request.MapPath("~/Upload"), Path.GetFileName(file.FileName));            try            {                file.SaveAs(fileName);                //tm.AttachmentPath = fileName;//得到全部model信息                tm.AttachmentPath = "../upload/" + Path.GetFileName(file.FileName);              //return Content("上传成功！", "text/plain");                return RedirectToAction("Show",tm);            }            catch            {                return Content("上传异常 ！", "text/plain");            }        }        public ActionResult Show(TestModel tm)        {            return View(tm);        }    }

 3、View

3.1 Upload.cshtml

@model MvcApplication1.Models.TestModel@{    ViewBag.Title = "Upload";}        @*enctype= "multipart/form-data"是必需有的，否则action接收不到相应的file*@    @using (Html.BeginForm("Upload", "Test", FormMethod.Post, new { enctype = "multipart/form-data" }))    {        @Html.LabelFor(mod => mod.Title)        
        @Html.EditorFor(mod => mod.Title)        
     
        @Html.LabelFor(mod => mod.Content)        
        @Html.EditorFor(mod => mod.Content)        
        上传文件        
                
        
            }

 3.2 Show.cshtml

@model MvcApplication1.Models.TestModel@{    ViewBag.Title = "Show";}
Show
@Html.LabelFor(mod => mod.Title)
@Html.EditorFor(mod => mod.Title)
     
@Html.LabelFor(mod => mod.Content)
@Html.EditorFor(mod => Model.Content)
