A large collection of C# utility and helper classes covering common .NET development tasks such as Excel/CSV/PDF handling, HTTP requests, JSON/XML serialization, caching, encryption, and database access. It aggregates dozens of standalone helper classes (SqlHelper, HttpHelper, ExcelHelper, CookieHelper, etc.) intended to be copied into projects.

Use cases

• read and write Excel files in C# with NPOI
• send HTTP requests from a .NET application
• convert between JSON, XML, CSV and DataTable in C#
• encrypt and decrypt strings in .NET
• generate QR codes, barcodes, and CAPTCHA images
• upload and download files over FTP in C#
• connect to MongoDB or Redis from C# with helper wrappers
• validate and sanitize SQL input strings

When to choose

• you want grab-and-go C# helper classes for common tasks without pulling many NuGet packages
• you maintain legacy .NET Framework projects and need battle-tested utility snippets
• you want a single reference collection of Chinese-documented .NET helpers

When to avoid

• you need a maintained, versioned package with a license and NuGet distribution
• you prefer modern, DI-friendly, async-first .NET libraries
• you work outside the .NET/C# ecosystem
