JsonLogic.Net is an implementation of JsonLogic in .Net platform. Implementation includes all supported operators documented on JsonLogic site.
JsonLogic.Net has a hard dependency on Newtonsoft.Json. It is a common library for json handling and very easy to use.
// The data that the rule will run against.
object data = new {MyNumber = 8};
// Rule definition retrieved as JSON text
string jsonText="{\">\": [{\"var\": \"MyNumber\"}, 3]}";
// Parse json into hierarchical structure
var rule = JObject.Parse(jsonText);
// Create an evaluator with default operators.
var evaluator = new JsonLogicEvaluator(EvaluateOperators.Default);
// Apply the rule to the data.
object result = evaluator.Apply(rule, data);The evaluator does not maintain any state and is thread-safe. Depending on your use case, you can add the evaluator as a singleton in your dependency injection container. You can also have multiple evaluators with different custom operations.
