Can we represent loops in the rules?

[karthik6244]

Say a complex object is there I want to iterate over that object and apply rule on one property, is this possible?

"Rules": [
{
"RuleName": "GiveDiscount10",
"SuccessEvent": "10",
"ErrorMessage": "One or more adjust rules failed.",
"ErrorType": "Error",
"RuleExpressionType": "LambdaExpression",
"Expression": "Loop through Complexobject AND input1.country == "india" AND input1.loyalityFactor <= 2 AND input1.totalPurchasesToDate >= 5000"
},

Assuming you are using at list or array.
You can use linq method such as Any, All , First, etc to check for some condition for items of array.

As for full-fledged support for looping, it is not possible via expression. You can write a utils class with a method to do looping for you and inject it in RulesEngine. You can refer it here - https://github.com/microsoft/RulesEngine/wiki/Getting-Started#resettings
