        newFile = model.Project.pname + DateTime.Now.ToString("yyyyMMddHHmmss") + Path.GetFileName(File1.FileName);
        File1.SaveAs(Server.MapPath("/项目材料/" + newFile));

        model.XMCL = "/项目材料/" + newFile;
        UpdateModel(model);
        db.SaveChanges();

Just ran into this earlier this week. Your form tag is missing the HTML attribute (enctype) to tell the server it is posting files. Here is the solution...

using (Html.BeginForm("Index", "Home", FormMethod.Post, new {enctype = "multipart/form-data"}))
