.NET技术

• 采用100%托管的C#语言编写，适用于.NET 2.0到4.6.X框架。

• 源代码在Blueprint订阅中可获得。

• NET和C#示例应用程序。

• 专为适应.NET框架类库创建的面向对象的设计。

• 所有的错误通过.NET异常类进行处理。

• 对象不需要被明确处理。

• 符合CLS(通用语言规范)。

• 不使用任何不安全的块。

• Visual Studio中集成了完整的文档。

• 为.NET2.0到.NET3.5单独构建。.NET4.0及以上版本的构建使用客户端配置文件编译。

主要功能

• 更快速：当创建Zip文件时无需使用任何临时文件，当涉及到创造全新的Zip文件时比Xceed Zip for .NET还快。

• 更安全：因为在创建Zip文件时没有使用任何临时文件，因此在Zip文件创建过程中未经授权的访问或修改文件的机会更少。

• 该产品的主要ZipWriter和ZipReader类分别使用任何可搜索的或非可查找基于流的对象作为目标或源Zip文件，实现具有完全灵活性和“即时”的压缩/解压缩。

• 轻量库。

• 一旦数据压缩已收到Zip文件的创建就开始：无需等待所有的文件，甚至是完整的文件。同样无需预先知道文件的数量或大小。

• Zip文件可以通过网络被立即发送或在写入进程开始时及时本地保存，并且剩余部分存档在它被压缩后也可用。

• 即使该组件仍在接收Zip文件，归档文件可以及时被提取和进一步处理。

• Zip压缩文件的大小或数量，对内存和磁盘空间要求绝对没有影响。

• 执行强大的Zip压缩/解压缩只需少量方法和属性。

• 支持PPMd、BZip2、BWT、Deflate以及Deflate64压缩方法。

• AES加密和解密都最大限度的支持WinZip的兼容性。组件使用得AES加密算法现在可以由开发者设置。

• 提供WinZip12兼容的唯一库，支持LZMA算法来提高某些情况下的压缩。注意：使用WinZip12的特殊JPEG再压缩功能的Zip文件不被支持。

• 提供了改进对文件名称和评论中国际字符支持的头文件中的UTF-8字符编码。

• 事件和属性，以监测和控制，还提供了拉链读/写的过程。

• 还提供了用于监测和控制Zip写入/读写过程的事件和属性。

• 与旧版的压缩工具兼容。

• ZipWriter可以生成该产品的ZipReader可读取的无压缩zip文件，大大提高了灵活性。

• 如果是传统的方法来压缩和解压缩的话，还是可以考虑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.
