本来想做一套上传公用的组建的，里面包含文件转码等功能，看来这些都只能后来一步一步加上了，先写下来。。。

1，引入脚本等

@{    Layout = null;}<!DOCTYPE html><html><head>    <title>Index</title>    <link href="http://www.mamicode.com/uploadify/uploadify.css" rel="stylesheet" /></head><body>    <input type="file" name="upload" id="upload" /></body></html><script src="http://www.mamicode.com/Scripts/jquery-1.11.1.min.js"></script><script src="http://www.mamicode.com/uploadify/jquery.uploadify.min.js"></script><script>    $(function () {        $(‘#upload‘).uploadify({            ‘formData‘: { ‘folder‘: ‘d:\\‘ },            ‘buttonText‘: ‘选择文件‘,            ‘buttonClass‘: ‘browser‘,            ‘removeCompleted‘: false,            ‘swf‘: ‘/uploadify/uploadify.swf‘,            ‘uploader‘: ‘/FileUp/Upload‘,            ‘fileSizeLimit‘:‘500MB‘,            ‘onError‘: function (event, id, fileObj, errorObj) {                if (errorObj.type === "File Size") {                    alert(‘超过文件上传大小限制（2M）！‘);                    return;                }                alert(errorObj.type + ‘, Error: ‘ + errorObj.info);            },        });    });</script>

2，后台上传代码

 public class FileUpController : Controller    {        public ActionResult Index()        {            return View();        }        public ContentResult Upload(HttpPostedFileBase fileData, string folder)        {            string filename = "";            if (null != fileData)            {                var length = fileData.ContentLength;                try                {                    filename = Path.GetFileName(fileData.FileName); //获得文件名                    saveFile(fileData, folder, filename);                }                catch (Exception ex)                {                    filename = ex.ToString();                }            }            return Content(filename);        }        [NonAction]        private bool saveFile(HttpPostedFileBase postedFile, string filepath, string saveName)        {            bool result = false;            if (!Directory.Exists(filepath))            {                Directory.CreateDirectory(filepath);            }            try            {                postedFile.SaveAs(Path.Combine(filepath, saveName));                result = true;            }            catch (Exception e)            {                throw new ApplicationException(e.Message);            }            return result;        }    }

3，设置web.config(在system.web节点中)

    <httpRuntime requestLengthDiskThreshold="256" maxRequestLength="2097151"/>   //假如超过256kb文件，其将缓存到硬盘
