• 源代碼在Blueprint訂閱中可獲得。

• NET和C#示例應用程序。

• 專為適應.NET框架類庫創(chuàng)建的面向?qū)ο蟮脑O計。

• 所有的錯誤通過.NET異常類進行處理。

• 對象不需要被明確處理。

• 符合CLS(通用語言規(guī)范)。

• 不使用任何不安全的塊。

• Visual Studio中集成了完整的文檔。

• 為.NET2.0到.NET3.5單獨構(gòu)建。.NET4.0及以上版本的構(gòu)建使用客戶端配置文件編譯。

主要功能

• 更快速：當創(chuàng)建Zip文件時無需使用任何臨時文件，當涉及到創(chuàng)造全新的Zip文件時比Xceed Zip for .NET還快。

• 更安全：因為在創(chuàng)建Zip文件時沒有使用任何臨時文件，因此在Zip文件創(chuàng)建過程中未經(jīng)授權(quán)的訪問或修改文件的機會更少。

• 該產(chǎn)品的主要ZipWriter和ZipReader類分別使用任何可搜索的或非可查找基于流的對象作為目標或源Zip文件，實現(xiàn)具有完全靈活性和“即時”的壓縮/解壓縮。

• 輕量庫。

• 一旦數(shù)據(jù)壓縮已收到Zip文件的創(chuàng)建就開始：無需等待所有的文件，甚至是完整的文件。同樣無需預先知道文件的數(shù)量或大小。

• Zip文件可以通過網(wǎng)絡被立即發(fā)送或在寫入進程開始時及時本地保存，并且剩余部分存檔在它被壓縮后也可用。

• 即使該組件仍在接收Zip文件，歸檔文件可以及時被提取和進一步處理。

• Zip壓縮文件的大小或數(shù)量，對內(nèi)存和磁盤空間要求絕對沒有影響。

• 執(zhí)行強大的Zip壓縮/解壓縮只需少量方法和屬性。

• 支持PPMd、BZip2、BWT、Deflate以及Deflate64壓縮方法。

• AES加密和解密都最大限度的支持WinZip的兼容性。組件使用得AES加密算法現(xiàn)在可以由開發(fā)者設置。

• 提供WinZip12兼容的唯一庫，支持LZMA算法來提高某些情況下的壓縮。注意：使用WinZip12的特殊JPEG再壓縮功能的Zip文件不被支持。

• 提供了改進對文件名稱和評論中國際字符支持的頭文件中的UTF-8字符編碼。

• 事件和屬性，以監(jiān)測和控制，還提供了拉鏈讀/寫的過程。

• 還提供了用于監(jiān)測和控制Zip寫入/讀寫過程的事件和屬性。

• 與舊版的壓縮工具兼容。

• ZipWriter可以生成該產(chǎn)品的ZipReader可讀取的無壓縮zip文件，大大提高了靈活性。

• 如果是傳統(tǒng)的方法來壓縮和解壓縮的話，還是可以考慮Xceed Zip for .NET。

.NET technology

• 100% managed code written in C# (Complete source code available in the Blueprint Edition of Xceed Real-Time Zip for .NET).
• Object-oriented design created specifically for version 2.0 and up of the .NET Framework.
• Seamless integration with the .NET base class libraries.
• All error handling works through .NET exception classes.
• Objects don’t need to be explicitly disposed of.
• 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 applications read and write fully standard Zip archives without resorting to any intermediate disk/memory storage or temporary files whatsoever. This means optimized performance ideal for high-demand server environments, Biztalk servers, diskless operations, I/O-intensive Web sites, or any situation where real-time streaming zip/unzip capabilities are needed, or where memory or disk space is at a premium.
• 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.
• Creation of Zip archives begins as soon as data to compress 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.
• Zip archives can be immediately sent over a network or saved locally as soon as the write process has begun, and the remainder of the archive becomes available as it is compressed.
• Fast: Not needing to use temporary files when creating a Zip file means it's slightly faster than Xceed Zip for .NET when it comes to creating entirely new Zip files.
• Secure: Because no temporary files are used while writing 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, Deflate64™, and PPMd compression methods. (The PPMd compression method is only available in 32-bit applications.)
• 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.
