html:
<form action="/home/upload" method="post" enctype="multipart/form-data"> <input type="file" name="files" multiple/> <input type="submit" value="提交" /> </form>
文件file 的name属性必填。
ActionResult:
[HttpPost] public ActionResult Upload(HttpPostedFileBase[] files) { var path = Server.MapPath("/File"); if (!Directory.Exists(path)) { Directory.CreateDirectory(path); } foreach (HttpPostedFileBase item in files) { item.SaveAs(Path.Combine(path, item.FileName)); } return Content("ok"); }
H5让我们轻松实现文件上传.
如果异步，代码如下
@{ Layout = null; } <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width" /> <title>Index</title> <script src="~/Scripts/jquery-1.8.2.min.js"></script> </head> <body> <div> <form id="formtable" enctype="multipart/form-data"> <input type="file" id="files" name="files" multiple /> <input type="button" id="btnok" value="提交" /> </form> </div> <script> $("#btnok").click(function () { var formdata = new FormData(document.getElementById("formtable")); $.ajax({ url: "/home/upload", data: formdata, type: 'post', datatype: 'json', // XMLHttpRequest会对 formdata 进行正确的处理 processData: false, //必须false才会自动加上正确Content-Type contentType: false, success: function (data) { alert(data); } }) }); </script> </body> </html>
public ActionResult Index() { return View(); } [HttpPost] public ActionResult Upload(HttpPostedFileBase[] files) { var path = Server.MapPath("/File"); if (!Directory.Exists(path)) { Directory.CreateDirectory(path); } foreach (HttpPostedFileBase item in files) { item.SaveAs(Path.Combine(path, item.FileName)); } return Content("ok"); }
