NReco.LambdaParser
A runtime parser for .NET that evaluates string expressions (formulas, method calls) by building dynamic LINQ expression trees.
What is NReco.LambdaParser?
NReco LambdaParser is a .NET library that parses and evaluates string expressions at runtime by building dynamic LINQ expression trees and compiling them to lambda delegates. It solves the need for runtime formula evaluation, method invocation, and property access in applications where expressions are not known at compile time, such as user-defined calculations or dynamic query builders.
.NET developers building applications that require runtime evaluation of expressions, such as formula engines, reporting tools, dynamic query systems, or configuration-driven calculations.
Developers choose LambdaParser for its seamless integration with .NET's LINQ ecosystem, support for complex expression syntax, runtime type resolution, and performance optimizations like caching, making it a robust alternative to manual expression tree construction or scripting engines.
