#csharp#c_sharp#linq#unity ZLinq is a high-performance, zero-allocation LINQ library for .NET and game engines like Unity and Godot. It improves on regular LINQ by avoiding memory allocations during method chaining, boosting speed and efficiency, especially in demanding apps like games. You use it by calling `AsValueEnumerable()` on collections, enabling faster queries with almost full compatibility with .NET 10 LINQ features. It supports advanced operations on arrays, spans, trees (like file systems and JSON), and SIMD for parallel processing. ZLinq also offers drop-in replacements to accelerate existing LINQ code without rewriting. This means you get faster, more memory-efficient data processing with minimal code changes[1][3][4]. https://github.com/Cysharp/ZLinq
