1. Model层用一个TestModel（与上一篇博文的TestModel 相同）

2. Controller层：public class TestController : Controller{//这是iframe页面的actionpublic ActionResult IframeView() { return View(); } public ActionResult View2() { 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 View2(TestModel tm, HttpPostedFileBase file) { if (file == null) { return Content("没有文件！", "text/plain"); } var fileName = Path.Combine(Request.MapPath("~/UploadFiles"), Path.GetFileName(file.FileName)); try { file.SaveAs(fileName); tm.AttachmentPath = fileName;//得到全部model信息 return Content("上传成功！", "text/plain"); } catch { return Content("上传异常 ！", "text/plain"); } }}View层，现在有两个View层，一个是iframe，叫IframeView，一个是View2，分别如下：IframeView@model UploadFile.Models.TestModel@{ Layout = null;}<!DOCTYPE html><html><head> <meta name="viewport" content="width=device-width" /> <title>IframeView</title></head><body> @*enctype= "multipart/form-data"是必需有的，否则action接收不到相应的file，这里报交的action是View2*@ @using (Html.BeginForm("View2", "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>别一个是View2@{ Layout = null;}<!DOCTYPE html><html><head> <meta name="viewport" content="width=device-width" /> <title>iframe异步上传</title></head><body> <form> <iframe width="500" height="500" src="/Test/IframeView"></iframe> </form></body>
