ASP.NET MVC上传文件

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41

public class TestController : Controller {     //     // GET: /Test/       public ActionResult Upload()     {         return View();     }     /// <summary>     /// 提交方法     /// </summary>     /// <param name="tm">模型数据</param>     /// <param name="file">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</param>     /// <returns></returns>     [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";

}

 

<!DOCTYPE html>

<html>

<head>

    <title>普通上传</title>

</head>

<body>

    @*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)

        <br />

        @Html.EditorFor(mod => mod.Title)

        <br />     <br />

        @Html.LabelFor(mod => mod.Content)

        <br />

        @Html.EditorFor(mod => mod.Content)

        <br />

        <span>上传文件</span>

        <br />

        <input type="file" name="file" />

        <br />

        <br />

        <input id="ButtonUpload" type="submit" value="提交" />

    }

</body>

</html>

3.2 Show.cshtml

@model MvcApplication1.Models.TestModel

 

@{

    ViewBag.Title = "Show";

}

 

<h2>Show</h2>

@Html.LabelFor(mod => mod.Title)

<br />

@Html.EditorFor(mod => mod.Title)

<br />     <br />

@Html.LabelFor(mod => mod.Content)

<br />

@Html.EditorFor(mod => Model.Content)

<br />
