• 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

    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 />

    <img src="@Model.AttachmentPath" alt="img" />
