RulesEngineEx 6.0.3

Overview

forked from which does not appear to be maintained anymore

Rules Engine is a library (not yet NuGet package) for abstracting business logic/rules/policies out of a system. It provides a simple way of giving you the ability to put your rules in a store outside the core logic of the system, thus ensuring that any change in rules don't affect the core system.

How to use it

Basic Example

1. Create the Workflow and add a Rule to it

var workflows = new Workflow[] {
    new Workflow {
        WorkflowName = "Test Workflow Rule 1",
        Rules = [
            new Rule {
                RuleName = "Test Rule",
                SuccessMessage = "Count is within tolerance",
                ErrorMessage = "Over expected",
                Expression = "count < 3"
            }
        ]
    }
};

2. Create instance of RulesEngine, parameter Workflows (optional ReSettings)

var rulesEngine = new RulesEngine.RulesEngine(workflows);

3. Create RuleParameters to pass as parameter to instance of RulesEngine

var ruleParameters = new RuleParameter[] {
    new RuleParameter("input1", new { count = 1 })
};

4. Excute all Workflows and associated Rules (parameters RuleParameters and CancellationToken)

await foreach (var async_rrt in rulesEngine.ExecuteAllWorkflows(ruleParameters, ct))
{
    async_rrt.OnSuccess((eventName) => {
        
    });

    async_rrt.OnFail(() => {
        
    });
}
