Windows Mobile Compact Framework Zip Components

Zip Library Options for the Compact Framework

When it comes to integrating ZIP file support into your applications, especially when developing for the .NET Compact Framework and Windows Mobile environments, it’s crucial to have the right tools at your disposal. In this blog post, we will explore the options available for handling ZIP files based on specific requirements such as compatibility, licensing, and functionality.

The Requirements: What You Need

Before delving into potential solutions, let’s outline the key requirements you may have for a ZIP library in your project:

  • Framework Compatibility: Support for .NET Compact Framework 2.0 and Windows Mobile 6.0 devices.
  • Functionality: The ability to unzip contents to a directory on a storage card; creation of zip files is not necessary.
  • Licensing: Must be suitable for use in corporate/commercial software; open-source options are preferred but must not include GPL or other viral licenses.

With these requirements in mind, let’s examine some available options that meet your needs.

Option 1: Xceed Zip for CF

One of the prominent libraries is the Xceed Zip for CF. This library is specifically designed for use with the .NET Compact Framework, allowing you to unzip files effectively. Here are some features worth noting:

  • Targeted Support: Designed to work seamlessly with Windows Mobile and .NET Compact Framework devices.
  • Usability: A user-friendly approach to extracting ZIP files without the overhead of creating them.
  • Licensing: Commercial licensing options available, making it suitable for corporate applications.

Pros:

  • Well-documented with comprehensive support.
  • Built specifically for the Compact Framework.

Cons:

  • May have a cost associated with commercial use.

Option 2: #ziplib

Another viable alternative is #ziplib, which you can find on icsharpcode.com. While it is released under a GPL license, it offers the possibility of use in closed-source, commercial applications. Here are some critical points about #ziplib:

  • Ease of Use: It is written in pure C# and does not have any external dependencies, which increases its likelihood of working within the Compact Framework environment.
  • Community-Driven: Being an open-source library, there is a community available for support and updates.

Pros:

  • Versatile for community support and contributions.
  • Lightweight and easy to implement due to the lack of external dependencies.

Cons:

  • The GPL license may not fit everyone’s licensing needs, so reviewing the specifics is crucial.

Testing Compatibility

Before committing to any library, especially #ziplib, it is essential to conduct your own tests to verify compatibility with the Compact Framework. Here are some points to consider:

  • Test on Actual Devices: If possible, perform tests on the supported devices to ensure proper functionality.
  • Review Documentation: Study the library documentation for any noted limitations regarding the Compact Framework.

Conclusion

When seeking a zip library for the Compact Framework, you have promising options like Xceed Zip for CF and #ziplib, each with its unique advantages and drawbacks. Considering your specific requirements—whether it’s cost, licensing, or functionality—will help you choose the best library for your application needs. Making an informed decision ensures your application can handle ZIP files effectively without compromising on quality or legality.
