RuleEngine

C# Rule Engine

4 steps

1 - Auto-Implement IRuleProcess on your target object

    public class TestObject : IRuleProcess 
    { 
        ...
        public object Result { get; set; }
        public bool Halted { get; set; }
        ...
    }
    ...  
    var obj = new TestObject { AccountId = 10, StringField = "some string" };

2 - Build a strongly-typed RuleHelper of your target type

    var helper = new RuleHelper<TestObject>();

3 - Apply conditions and rules

    helper.AddCondition(x => x.StringField, StringOperand.DoesNotEqual, null, Conditional.And);
    helper.AddCondition(x => x.StringField, StringOperand.DoesNotContain, "str", Conditional.Or);
    helper.Then("then case");
    helper.Else("else case");

4 - Dispatch Rule Engine (extension method on IRuleProcess)

    obj.Apply(helper);
    Console.Out.WriteLine(obj.Result); // == "then case"
