RuleWright.Json.SystemText

The System.Text.Json adapter for RuleWright: implements IRuleJsonReader so the engine can read rule documents, plus helpers for using JSON payloads as facts.

Install

dotnet add package RuleWright.Json.SystemText

Already included in RuleWright — install this directly only if you reference RuleWright.Execution piecewise. Prefer RuleWright.Json.NewtonsoftJson if your application already standardises on Newtonsoft.Json; the two are parity-tested against each other, and swapping adapters is the only change.

Read rule documents

var engine = new RuleWrightBuilder()
    .UseJsonReader(new SystemTextJsonReader())
    .Build();

Comments and trailing commas are tolerated, so hand-written rule files stay pleasant to edit. Malformed JSON surfaces as RuleParseException.

Use a JSON payload as a fact

SystemTextJsonFacts.ToDictionary converts a JsonElement into the dictionary shape the engine's interpreter evaluates — useful when facts arrive as JSON over HTTP and there is no CLR type to bind them to.

using JsonDocument payload = JsonDocument.Parse(requestBody);
Dictionary<string, object?> fact = SystemTextJsonFacts.ToDictionary(payload.RootElement);

RuleEvaluationResult result = engine.Evaluate(ruleSet, fact);
// result.CompilationMode == CompilationMode.Interpreted

Nested objects become nested dictionaries and arrays become object?[]. Numbers become long when integral, otherwise decimal when exactly representable, otherwise double — the same policy the rule parser applies to constants, so a fact and a rule constant of the same JSON text compare as equal.

Keys match exactly by default, and a rule's Order.Total does not find a camelCase "order": { "total": … } — which is what most web clients send. Pass a key comparer to match without regard to case, at every level:

Dictionary<string, object?> fact = SystemTextJsonFacts.ToDictionary(payload.RootElement, StringComparer.OrdinalIgnoreCase);

Two properties of one object that the comparer treats as the same key ("Total" and "total") throw ArgumentException rather than one silently replacing the other.

Requirements

.NET Framework 4.8, .NET Standard 2.0, .NET 8.0 or .NET 10.0. System.Text.Json is in-box from .NET 8 on; the down-level legs take a package reference for it.

RuleWright The RuleWright rule engine — everything you need in one package: the core domain model, JSON parsing and schema validation, the expression-tree evaluation engine, the System.Text.Json adapter, and the built-in custom functions. Rules are plain JSON; evaluation is compiled expression trees. Install this unless you want to pick pieces individually.	389
