Silverlight Day 5 - 介紹 Silverlight 多檔上傳元件
在 ASP.Net 2.0 的時候，多半都參考【ASP.NET File Upload 檔案上傳套件】客製多檔案上傳的元件。
亦或是，直接使用其他 AJAX 或是已 Flash 為基礎的上傳套件來達成相同的功能，而我多半都是使用 SWFUpload 元件來實作。
日前，因為 Flash Player 10 Beta 的釋出，曾經讓 SWFUpload 2.1 癱瘓一陣子，必須使用 2.2 版本才能夠運作。
(參考: Flash Player 10 Beta 相關討論)
而隨著 Silverlight 的出現，mpost 在 CodePlex 釋出 Silverlight Multi File Uploader v2.2 多檔案上傳套件，主要特色如下：
Features:
- Select multiple files to upload (可以一次選擇多檔案上傳)
- Upload multiple files at the same time (同時上傳多個檔案)
- Cancel a single upload, or clear the full list (可取消檔案上傳動作)
- Shows the overall progress (顯示上傳進度)
For developers: (對於開發者而言，方便性如下：)
- Full Source Code Included!
- Configure file extension filter (for example, only .jpg files) (可設定限制上傳檔案類型)
- Configure maximum file size (可設定限制單一檔案容量大小)
- Configure the number of simultaneous uploads (設定單一時間上傳檔案個數)
- Input for custom parameters
- Basic webservice included
- Change the default color by setting a single parameter
