.NET技術(shù)

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

• 是純粹的面向?qū)ο笤O(shè)計(jì)的Silverlight 2.0組件

• 完全兼容Silverlight的基礎(chǔ)類庫

• 可通過Silverlight的異常類處理所有的控件異常

• 遵從CLS（通用語言規(guī)范）

• 不使用不安全的模塊，必須有最小權(quán)限的要求

• 文檔完全集成到Visual Studio中

• 有VB.NET 和 C#的示例程序

主要特點(diǎn)

• 允許開發(fā)人員增加壓縮和解壓縮功能到任意的Silverlight 2.0應(yīng)用程序，使操作更加快速方便。壓縮和非壓縮的文件不需轉(zhuǎn)換為中間的磁盤/存儲(chǔ)文件或臨時(shí)文件，可與Silverlight完美整合：因?yàn)榭丶⒉恍枰镜卮疟P的寫入權(quán)限

• 該產(chǎn)品主要的ZipWriter和ZipReader類可使用任何可尋的或非可尋流的對(duì)象作為目標(biāo)或源壓縮文件，并各自支持靈活的實(shí)時(shí)壓縮/解壓縮

• 輕量級(jí)庫

• 支持盡可能快的壓縮已收到的數(shù)據(jù)：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數(shù)量或大小

• 可通過網(wǎng)絡(luò)實(shí)時(shí)傳送已壓縮的Zip文件，并且未傳輸?shù)钠溆辔臋n仍然可作為壓縮文件使用

• 安全性：因?yàn)楫?dāng)創(chuàng)建Zip文件不會(huì)創(chuàng)建任何的臨時(shí)文件，所以在創(chuàng)建Zip的過程中對(duì)未經(jīng)授權(quán)的訪問或文件的修改都是不可能的

• 即使組件仍然在接收Zip壓縮文件，壓縮文件仍可隨時(shí)的被提取，并可以立即作進(jìn)一步處理

• 在Zip壓縮文件中，文件的數(shù)量或大小絕對(duì)不會(huì)受內(nèi)存和磁盤空間的要求所影響

• 僅僅使用幾個(gè)方法和屬性，就能實(shí)現(xiàn)強(qiáng)大的Zip壓縮/提取

• 支持BZip2, BWT, Deflate, 和 Deflate64™壓縮算法

• 支持AES加密和解密，這是為了最大化的兼容WinZip

• 同時(shí)也提供了監(jiān)測(cè)和控制Zip的讀/寫過程的事件和屬性

• 支持讀取Xceed Unicode Extra Header，所以它現(xiàn)在可以用Unicode字符保存文件名。這對(duì)于處理國際字符是非常有用的

• 能與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.
