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