ASP.NET MVC上传文件
出处:http://www.cnblogs.com/zhouhb/p/3906714.html
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;
}
}

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 />
