在 .NET 應用程式中提升試算表資料分析

9月 5, 2024
EPPlus v7.3.0 添加支援更複雜的統計和數學運算的新功能，從而提升了其公式計算能力。

EPPlus is a powerful and versatile .NET library for managing and manipulating Microsoft Excel files using the Office Open XML (OOXML) format. It is a lightweight and efficient library that is easy to use and can be integrated into a wide range of applications. It allows developers to create, read and modify spreadsheets without dependencies on any other library. Features include pivot tables, styling, VBA/Form controls, conditional formatting, charts, tables, formula calculation, data validation, pictures/shapes, and more.

The EPPlus v7.3.0 update introduces four new functions that are supported in formula calculations, enhancing the library's capability for data analysis within Microsoft Excel spreadsheets. The GROWTH function enables exponential growth calculations, while DPRODUCT allows the multiplication of values in a field of a list or database based on specified criteria. The DSTDEV and DSTDEVP functions calculate the standard deviation of values in a field within a list or database, but they differ in their scope. DSTDEV is for samples, while DSTDEVP is used for entire populations. These functions allow developers to perform more complex statistical and mathematical operations directly within spreadsheet documents, significantly improving the efficiency of data-driven applications.

To see a full list of what's new in v7.3.0, see our release notes.

EPPlus is licensed per developer and is available as both perpetual licenses and subscription based licenses with periods of 1 year and 2 years, which include support and upgrades. See our EPPlus licensing page for full details.

Sticky note annotations are digital notes that can be attached to specific parts of a document or webpage. They allow users to highlight text, add comments, or ask questions directly on the content they are viewing. This feature is particularly useful for collaboration, as it enables multiple people to contribute to the same document and easily see each other's thoughts and insights. Sticky note annotations can also be used for personal reference, helping users to remember important points or track their progress through a document.

Several ASP.NET Core PDF viewer controls offer support for sticky note annotations including:

  • Document Solutions for PDF by MESCIUS empowers users to add comments and reminders directly on PDFs with digital sticky notes.
  • ImageGear for .NET by Accusoft allows for attaching interactive sticky notes to PDFs, streamlining information sharing and review.
  • Syncfusion ASP.NET Core PDF facilitates in-document annotation using digital sticky notes for collaborative editing and feedback.

透過您整合式開發環境（IDE）中強大的代碼檢查功能減少錯誤並提高代碼可維護性。

Code inspection is a static analysis tool that examines source code for potential errors, inconsistencies, or stylistic deviations. It automatically identifies issues like syntax errors, undefined variables, unused code, and violations of coding standards. By detecting these problems early in the development process, the inspection of code helps developers improve code quality, maintainability, and readability. This ultimately leads to more efficient development, reduced debugging time, and fewer software defects.

Several IDEs offer support for code inspection including:

  • IntelliJ IDEA by JetBrains offers comprehensive code inspection, including real-time error detection and suggestions for improvements.
  • Delphi Professional by Embarcadero provides a robust code inspection framework, helping developers identify potential issues and maintain code quality.
  • EiffelStudio by Eiffel Software excels at code inspection through its strong type system and contract-based programming, ensuring code correctness and reliability.
  • Microsoft Visual Studio Professional offers a suite of code inspection tools, including static analysis, to help developers write clean and efficient code.
