uploadify插件的確是個好東西，但是對於像我這樣才接觸的人來說，確實被坑慘了。
本來準備將uploadify用在ASP.NET MVC中試試，可是試了N久，沒試個所以然來，這還是主要怪自己對MVC不熟悉。好吧，MVC 不行 Web Form 總該可以吧！
因爲自己今天才接觸這個插件，所以更不就不清楚怎麼用，官網上面的又是一個PHP的demo。。。確實沒有辦法，在網上搜了很久，才知道結合一般處理程序實現服務器端文件處理，其實這些都不是我主要想說的。我想說的是網上很對uploadify初始化的代碼很有問題，比如：下面代碼
$(
"#uploadify"
).uploadify({
'uploader': 'JS/jquery.uploadify-v2.1.0/uploadify.swf',
'script': 'UploadHandler.ashx',
'cancelImg': 'JS/jquery.uploadify-v2.1.0/cancel.png',
'folder':'UploadFile',
'queueID':'fileQueue',
'auto':false,
'multi':true
}); });在這段代碼中有的Option在3.2.1的版本中根本就沒有...所以怎麼用也得不到想要的結果...在3.2.1的版本中一般處理程序應該寫在‘uploader’選項中，在文件上傳之後就會進入一般處理程序對文件進行處理，
也就是‘uploader’:'UploadHandler.ashx'
在3.2.1版本中有一下option,後面是它的默認值
