Asp.net和C#：檔案上傳元件

Asp.net和C#：檔案上傳元件
最常見的為Visual Studio內建的FILEUPLOAD和外卦的SWFUPLOAD。
由於本人開發環境是Visual Studio 2005 ( .NET Framework 2.0)，
在此環境下：
一個FILEUPLOAD一次只能上一個檔案(較新的Visual Studio 己可以次上傳多個)，
而SWFUPLOAD一次可以上傳多個檔案(但不是內建，設定麻煩)。
因此在這裡的SWFUPLOAD就比FILEUPLOAD強一些。

SWFUPLOAD：由SWF和JS完成檔名LOOP的上傳動作。
1.在 SwfUpload 官網中的External links/Demos中可以看到php下SWFUPLOAD的範例
2.在Featured/Downloads下可下載asp.net C#的範例，範例為產生縮圖。
若要要有上傳的動做需自行手寫，這就要看說明書的。
3.說明書：SWFUpload 使用详解
//upload.aspx.cs // Get the data
      HttpPostedFile jpeg_image_upload = Request.Files["Filedata"];
      string file_path = Server.MapPath("~/upload/");
      if (!Directory.Exists(file_path)) { Directory.CreateDirectory(file_path); }
      Request.Files["Filedata"].SaveAs(file_path + Request.Files["Filedata"].FileName);//存圖
