Com.RickSeven.FormulaEngine

A powerful and flexible formula evaluation engine using Roslyn Scripting with dynamic runtime context. Ideal for scenarios where business logic needs to be defined at runtime through C# expressions or formulas.

🚀 Features

  • Evaluate C# expressions dynamically
  • Inject dynamic variables and objects into script context
  • Auto-generates strongly-typed global context types at runtime
  • Supports full Roslyn scripting capabilities
  • Handles nested objects, Math functions, string ops, and more
  • No external dependencies other than Roslyn and BCL

🎞 Installation

Install via NuGet:

dotnet add package Com.RickSeven.FormulaEngine.Core --version 1.0.0

Or using the NuGet Package Manager:

PM> Install-Package Com.RickSeven.FormulaEngine.Core

🧠 Usage Example

var context = new Dictionary<string, object>
{
    { "revenue", 10000 },
    { "cost", 7000 },
    { "margin", 0.3 },
    { "desc", "Result is: " }
};

string formula = "desc + ((revenue - cost) * margin).ToString()";

var engine = new FormulaEngine();
var result = engine.Evaluate(formula, context);

// Output: "Result is: 900"
Console.WriteLine(result);

Supports advanced expressions:

var context = new Dictionary<string, object>
{
    { "baseValue", 2.0 },
    { "exponent", 3.0 }
};

string formula = "Math.Pow(baseValue, exponent)";

var engine = new FormulaEngine();
var result = engine.Evaluate(formula, context);

// Output: 8.0
Console.WriteLine(result);
