.NET技术

• 100％使用C#托管代码编写。（其中Xceed Real-Time Zip for Silverlight Blueprint版本提供了完整的源代码）

• 是纯粹的面向对象设计的Silverlight 2.0组件

• 完全兼容Silverlight的基础类库

• 可通过Silverlight的异常类处理所有的控件异常

• 遵从CLS（通用语言规范）

• 不使用不安全的模块，必须有最小权限的要求

• 文档完全集成到Visual Studio中

• 有VB.NET 和 C#的示例程序

主要特点

• 允许开发人员增加压缩和解压缩功能到任意的Silverlight 2.0应用程序，使操作更加快速方便。压缩和非压缩的文件不需转换为中间的磁盘/存储文件或临时文件，可与Silverlight完美整合：因为控件并不需要本地磁盘的写入权限

• 该产品主要的ZipWriter和ZipReader类可使用任何可寻的或非可寻流的对象作为目标或源压缩文件，并各自支持灵活的实时压缩/解压缩

• 轻量级库

• 支持尽可能快的压缩已收到的数据：不需等待所有文件，甚至不需要完整的文件。也不需要事先知道文件的数量或大小

• 可通过网络实时传送已压缩的Zip文件，并且未传输的其余文档仍然可作为压缩文件使用

• 安全性：因为当创建Zip文件不会创建任何的临时文件，所以在创建Zip的过程中对未经授权的访问或文件的修改都是不可能的

• 即使组件仍然在接收Zip压缩文件，压缩文件仍可随时的被提取，并可以立即作进一步处理

• 在Zip压缩文件中，文件的数量或大小绝对不会受内存和磁盘空间的要求所影响

• 仅仅使用几个方法和属性，就能实现强大的Zip压缩/提取

• 支持BZip2, BWT, Deflate, 和 Deflate64™压缩算法

• 支持AES加密和解密，这是为了最大化的兼容WinZip

• 同时也提供了监测和控制Zip的读/写过程的事件和属性

• 支持读取Xceed Unicode Extra Header，所以它现在可以用Unicode字符保存文件名。这对于处理国际字符是非常有用的

• 能与Xceed Upload for Silverlight完全兼容

.NET technology

• 100% managed code written in C#. (Complete source code available in the Blueprint Edition of Xceed Real-Time Zip for Silverlight.)
• Object-oriented design created specifically for Silverlight 2.
• Seamless integration with the Silverlight base class libraries.
• All error handling works through Silverlight exception classes.
• CLS compliant (Common Language Specification).
• Does not use unsafe blocks for minimal permission requirements.
• Documentation fully integrated into Visual Studio
• VB.NET and C# sample applications.

Major Features

• Lets developers add zip and unzip capabilities to any Silverlight 2 application, quickly and easily. Compresses and uncompresses files without resorting to intermediate disk/memory storage or temporary files, making it the perfect match for Silverlight: it needs no local write access.
• The product's main ZipWriter and ZipReader classes use any seekable or non-seekable Stream-based object as the target or source Zip archive, respectively, for complete flexibility and “on-the-fly” compression/decompression.
• Lightweight libraries.
• Compression starts as soon as data has been received: no waiting for all of the files, or even for complete files. Doesn’t need to know in advance the number or size of files.
• Transfer of the Zip archive over a network can begin immediately, and the remainder of the archive becomes available as it is compressed.
• Secure: Because no temporary files are used while creating a Zip file, there is less chance of unauthorized access or modification of files during the Zip creation process
• Archived files are extracted and available instantly for further processing even if the component is still receiving the Zip archive.
• The size or number of files in a Zip archive has absolutely no impact on memory and disk-space requirements.
• Just a few methods and properties are needed to perform powerful Zip compression/extraction.
• Supports the BZip2, BWT, Deflate, and Deflate64™ compression algorithms.
• AES encryption and decryption are supported for maximum WinZip compatibility.
• Events and properties to monitor and control the Zip writing/reading processes are also provided.
• Reads the Xceed Unicode Extra Header, so it can now preserve filenames with Unicode characters. Very useful for handling international characters.
• Works seamlessly with Xceed Upload for Silverlight.
