MVC进行多文件上传

 <form name="form1" method="post" action="地址" id="form1" multiple="multiple" enctype="multipart/form-data">
    <input type="file" name="upload_fujian" class="upload_fujian" multiple="multiple" />
 </form>

 $('.upload_fujian').change(
                function () {
                    var files = $(this)[0].files;
                    for (var i = 0, f; f = files[i]; i++) {
                            if (f.size < 2 * 1024 * 1024) {
                                //如果需要自动提交表单，可以使用下面的这行代码，否者就等到用户点击按钮再上传文件
                                //$('.upload_media').parent().submit();
                            } else {
                                alert(f.name + '文件超出上传大小限制！');
                            }
                        }
                }
                )

       public ActionResult Noticeadd(FormCollection form1) {

            HttpFileCollectionBase file_ = Request.Files;
          
            for (int i = 0; i < file_.Count; i++)
            {
                //文件大小  
                long size = file_[i].ContentLength;

                {
                    string saveName = DateTime.Now.ToString("yyyyMMdd");
                    string file = "\\Areas\\gonggao\\fujian\\" + saveName + "\\";
                    string path = System.Web.HttpContext.Current.Request.PhysicalApplicationPath + file;
                    if (!Directory.Exists(path))
                    {
                        Directory.CreateDirectory(path);
                        DirectoryInfo dirInfo = new DirectoryInfo(path);

                    }
                     file_[i].SaveAs(path + name);

                     //file + name 为文件名可以保存至数据库，我这里是测试，直接返回到前台了
