Summary of Changes
Hello @shps951023, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request focuses on modernizing the project's build configuration and restoring critical components that were previously in a 'Legacy' state. It also significantly enhances the project's documentation and packaging, making it easier for new users to understand and utilize the MiniExcel library.
Highlights
- Project Configuration Updates: The target framework for
MiniExcel.Benchmarks.csprojwas updated fromnet10.0tonet9.0, andnet10.0was removed from the general target frameworks inDirectory.Build.props. - Copyright and Packaging Enhancements: The copyright notice in
Directory.Build.propswas updated, andicon.pngandREADME.mdwere added to the project's packaging configuration. - Core Functionality Restoration: Several core files (
Attributes.cs,Configuration.cs,ExcelType.cs,ExcelTypeHelper.cs,MiniExcel.cs) were moved from aLegacyfolder, effectively reintroducing and organizing essential Excel processing components. - New Project Documentation: A comprehensive
README.mdfile was added to thesrcdirectory, providing detailed project information, features, getting started guides, and performance benchmarks.

Code Review
This pull request updates the project structure by removing the 'Legacy' folder and restoring core functionality into the main MiniExcel library. It also updates target frameworks and packaging information. The changes are a good step towards cleaning up the codebase. My review has identified a critical bug in MiniExcel.cs that could lead to data loss through unintentional file overwrites. I've also found several areas for improvement regarding API consistency, feature completeness, and robustness in stream handling. Additionally, there are some minor issues in the new README.md and a potential misconfiguration in the packaging setup in Directory.Build.props. I've provided specific suggestions for all these points.

The path ../README.md points to the README file in the repository's root directory. However, this pull request introduces a new src/README.md file. If the intention is to package this new README, the path should be updated to README.md.

The phrasing here is a bit awkward. For better clarity and professionalism, consider rephrasing.
| MiniExcel is simple and efficient to avoid OOM's .NET processing Excel tool. | |
| MiniExcel is a simple and efficient .NET library for processing Excel files, designed to avoid Out-of-Memory (OOM) errors. |

| At present, most popular frameworks need to load all the data into the memory to facilitate operation, but it will cause memory consumption problems. MiniExcel tries to use algorithm from a stream to reduce the original 1000 MB occupation to a few MB to avoid OOM(out of memory). |

This sentence could be more direct and easier to understand. Consider simplifying it to improve readability.

| Most popular Excel processing libraries load the entire file into memory, which can lead to high memory consumption and OOM errors with large files. MiniExcel uses a streaming approach to process Excel data, significantly reducing memory usage. |
