Recently, I've learned how ASP. NET MVC uploads files by referencing network data. Most basic, not with jquery and other technologies.

1. Define Model

public class Testmodel
{
[Display (Name = "title")]
[Required]
public string Title
{
Get
Set
}
[Display (Name = "content")]
[Required]
[DataType (Datatype.multilinetext)]
public string Content
{
Get
Set
}
public string AttachmentPath
{
Get
Set
}
}

2. Controller

1234567891011121314151617181920212223242526272829303132333435363738394041 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>    <title>普通上传</title><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>

3.2 show.cshtml

@model MvcApplication1.Models.TestModel @{      ViewBag.Title = "Show" ; } @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："@Model.AttachmentPath" alt="img" />
