UserDefinedExpressions

UserDefinedExpressions is a .NET library to safely invoke (evaluate) User Defined Expressions (Formulas) using Roslyn Scripting Engine

One of the most common tasks in business applications is to allow end-users to configure business rules on their own. This library allows developers to evaluate C# expressions written by end-users (as if they were writing Excel formulas) but it's safe against malicious code.

Installation

Just install nuget package UserDefinedExpressions, add using UserDefinedExpressions and start using (see examples below).
See documentation below, or more examples in unit tests.

Documentation

Sample usage:


public class SalesOrderHeader
{
    public decimal TotalDue { get; set; }
	public decimal Freight { get; set; }
}

var isHeavyOrExpensiveFormula = UserDefinedExpression<SalesOrderHeader, bool>.Create("TotalDue > 1000 || Freight > 1000");
var order = new SalesOrderHeader() { TotalDue = 1200, Freight = 700 };
bool isHeavyOrExpensive = isHeavyOrExpensiveFormula.Invoke(order);
