Advanced reflection utilities for .NET — type parsing, fluent reflection extensions, smart type conversion, and dynamic invocation. Zero external dependencies.
dotnet add package Cocoar.Reflectensions # Core library
dotnet add package Cocoar.Reflectensions.Invoke # + Dynamic method invocation
dotnet add package Cocoar.Reflectensions.ExpandableObject # + Dynamic expandable objectsYou only need Core unless you need invocation or expandable objects. Targets .NET 8.0 and .NET Standard 2.0.
using Cocoar.Reflectensions;
// Parse complex type names from strings
var type = TypeHelper.FindType("Dictionary<string, List<int>>");
// Fluent reflection queries
var methods = typeof(MyClass).GetMethods()
.WithName("Process")
.WithReturnType<Task>()
.WithParametersOfType(typeof(string));
// Smart type conversion — discovers implicit operators automatically
DateTime date = "2021-03-21T15:50:17+00:00".Reflect().To<DateTime>();
int number = "42".Reflect().To<int>();
Truck truck = camaro.Reflect().To<Truck>(); // uses implicit operator- Advanced Type Parsing — Parse
Dictionary<string, List<int>>from strings, with custom type mappings. - Fluent Reflection API — Chainable LINQ-style extensions for types, methods, properties, and parameters.
- Smart Type Conversion —
Reflect().To<T>()with automatic implicit operator detection, Parse/TryParse, IConvertible fallbacks, and optimized hot paths (8x faster for common conversions). - Zero-Cost Abstractions —
ObjectReflection<T>readonly structs with no heap allocations. - Dynamic Invocation — Invoke methods via MethodInfo with automatic parameter type conversion and async support.
- Expandable Objects — Dynamic objects with dictionary-like behavior and
INotifyPropertyChanged. - Zero Dependencies — Completely self-contained, no third-party NuGet packages.
