.NET技术

• 与微软Silverlight 一起发布，在Silverlight 2的后续版本中会随着其更新而更新。

• 完全用C#编写。

• 在Blueprint版本提供了完整的源代码。

• 基于一个灵活的和可扩展的对象模型。

• 所有的文档完全都集成到Visual Studio中。

• 包含各样的VB.NET，C#，和 JavaScript示例应用程序让您快速入门。

主要特性

• 让您快速方便的增加多文件上传功能到任何的Microsoft Silverlight 应用程序中。直接上传图片和其它文件到集成Silverlight的网页。

• 所有上传操作都是异步的，因此集成该控件的网页仍然可以在整个传送过程中响应其他用户交互。

• 一次性能上传处理多个文件。

• 从您的Silverlight表单上传字段内容和字符串到Web服务器会变得更加简单：字段会自动收集并格式化成一个标准格式的请求。

• 帮助并为您的最终用户提供一个完美的Silverlight 体验，诸如显示进度信息。

• 当它正在上传的时候让你压缩数据。支持可控压缩级别的GZip和Deflate压缩方式 。

• 丰富的事件让您的应用程序能监测和控制上传过程中的每一步操作。

• 提供多个不同版本的上传方法：从简单的“fire-and-forget”版本到让您控制每一步操作。Static和instance版本让你使用适合您需求的组件。

• 支持延迟上传，让您的应用程序收集文件和字符串可以在准备就绪的情况下执行传送。

• 利用组件发出HTTP协议请求，通过“multipart/form-data”内容类型，使用标准的MIME格式上传数据，这意味着任何最新的Web服务器都将能处理数据。

• 可以设置自定义HTTP协议请求标题（主标题和项目标题）。

• 在边界中使用的HTTP请求可以被指定。

• Base64编码可以支持网络浏览器，不允许上传非ASCII数据。

• 同时支持ASP.NET和AJAX。

包含辅助服务器类

• Xceed HTTP服务器工具为ASP.NET提供帮助处理压缩/编码数据。

• 在UploadedFile和UploadedFiles类准确的处理压缩/编码的文件：因为这些类是基于文件系统的核心，他们处理这类文件的工作与一般文件一样简单。

• UploadedString类有助于简化处理压缩/编码字符串。

其它特性

• 客户端执行：如果不使用压缩或编码，那服务器端组件或代码也不需要。

• 经IIS测试，符合任何HTTP 1.1标准兼容的Web服务器。

• 在刷新或者上传后的过程中不会触发页面。

• 支持Unicode文件名。

• 支持Windows Vista，Windows XP SP2， Windows 2000，和 Windows Server 2003 (除了 IA-64)操作系统，并且能在Internet Explorer 7 和 6，Firefox 2 和1.5，以及 Safari (Mac OS 10.4.8+ only)浏览器上运行。有些操作系统/浏览器的组合是不支持Silverlight的。

.NET technology

• Created with Microsoft Silverlight, will be updated for future versions of Silverlight as they become available.
• Written entirely in C#.
• Complete source code is available in the Blueprint Edition.
• Based on a flexible and extensible object model.
• Comprehensive documentation fully integrated into Visual Studio is provided.
• Includes a variety of VB.NET, C#, and JavaScript sample applications to get you started.

Major Features

• Lets you quickly and easily add multi-file upload capabilities to any Microsoft Silverlight application. Upload images and other files directly from Silverlight-hosting Web pages.
• All upload operations are asynchronous, so the hosting Web page remains perfectly responsive and usable throughout the transfer.
• Uploaders can process multiple files a single transaction.
• Uploading field contents and strings from your Silverlight forms to the Web server is simple: fields are automatically gathered and formatted into a standard request.
• Helps you deliver a beautiful Silverlight experience to your end-users, such as displaying progress information.
• Lets you compress data as it is being uploaded. Supports GZip and Deflate, with controllable compression level.
• Rich events let your application monitor and control every step of an upload operation.
• Several versions of the upload methods are provided: from simple “fire-and-forget” versions to ones letting you control everything. Static and instance versions let you use the component to suit your needs.
• Uploads can be deferred, letting your application gather files and strings and then perform the actual transfer when ready.
• The HTTP requests produced by the component use the standard MIME format for uploading data through the “multipart/form-data” content type, meaning any modern Web server should be able to handle the data.
• Custom HTTP request headers (main and item headers) can be set.
• The boundary used in the HTTP request can be specified.
• Base64 encoding is available to support Web browsers that do not allow the upload of non-ASCII data.
• An alternative to ASP.NET and AJAX.

Included helper server classes

• Xceed Http Server Tools for ASP.NET is provided to help deal with compressed/encoded data.
• The UploadedFile and UploadedFiles classes seamlessly handle compressed/encoded files: because these classes are based on the FileSystem Core, they make dealing with such files as easy as working with regular files.
• The UploadedString class helps simplify handling compressed/encoded strings.

Other features

• Client-side execution: no server-side component or code required if compression or encoding isn’t used.
• Tested with IIS, but is compatible with any HTTP 1.1 standards-compliant Web server.
• Does not trigger a page refresh during or after an upload.
• Supports Unicode filenames.
• Supports Windows Vista, Windows XP SP2, Windows 2000, and Windows Server 2003 (except IA-64), and runs in Internet Explorer 7 and 6, Firefox 2 and 1.5, and Safari (Mac OS 10.4.8+ only). Some OS/browser combinations are not supported by Silverlight.
