处理MVC.net中多个文件上传的最佳方式

. NET MVC上传扩展很好。http://demos.telerik.com/aspnet-mvc/razor/upload

我尝试过plupload和jquery文件上传

Jquery文件上传工作得最好，因为plupload混淆了表单提交，我不能得到防伪造令牌工作(还!)。

你也可以考虑上传，但我自己还没有尝试过。

telerik库仅对某些项目免费，例如开源/非商业项目。

这里是代码我放在一起使用的jQuery文件上传…

和控制器…

[HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Upload(int? id, IEnumerable<HttpPostedFileBase> files)
        {
            foreach (var file in files)
            {
                if (file.ContentLength > 0)
                {
