StringToLinq

StringToLinq is a simple .NET library that transforms string expressions into Linq Expressions. This library enables dynamic generation of complex Linq queries from string inputs, providing a level of flexibility for Linq-based querying.

Features

  • Converts string expressions into Linq Expressions.
  • Supports arithmetic, comparison, and logical operators.
  • Supports nested types and properties.
  • Provides a customizable syntax.
  • Fully compatible with Linq's Expression<Func<T, bool>> predicates.

Quick Start

Install the library through NuGet or by cloning the repository. (Nuget soon)

Define the string that contains the expression you want to parse.

string input = "Name eq \"John Doe\" and (Age gt 30 or Department eq \"Sales\")";

Use the ToPredicate method from StringExpression to convert the string expression into a Linq Expression.

Expression<Func<Employee, bool>> expr = StringExpression.ToPredicate<Employee>(input);

Use the generated expression in a Linq query.

IEnumerable<Employee> results = employees.AsQueryable().Where(expr);

How it Works

The library works in three steps:

  • Parsing the input string into a list of tokens.
  • Building an Abstract Syntax Tree (AST) from the tokens.
  • Generating a Linq Expression from the AST.

These steps are performed by the ToPredicate method.
