ASP.NET MVC上传文件

2024-09-08 11:51:28   216人阅读

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=http://www.mamicode.com/"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 />
