var workflows = JsonConvert.DeserializeObject<List<Workflow>>(rulesStr)!;
var bre = new RulesEngine.RulesEngine(workflows.ToArray());

List<RuleResultTree> resultList = await bre.ExecuteAllRulesAsync("Test", rp1,rp2,rp3);
var discount = 1.0;
foreach (var item in resultList)
{
    if (item.ActionResult != null && item.ActionResult.Output != null)
    {
        Console.WriteLine($"{item.Rule.RuleName} 折扣优惠：{item.ActionResult.Output}");
        discount = discount * (double)item.ActionResult.Output;

}
Console.WriteLine($"最终折扣:{discount}");

When the program runs to line 65, an error message appears in item.ExceptionMessage: "Exception while parsing expression buyer.Age < 18 - No property or field 'Age' exists in type 'Buyer' ". The reason is that the error occurs when a RuleParameter with the name buyer is defined in line 40 of the code and the Value class name of that RuleParameter is the same as buyer. Changing buyer to buy and changing buyer.Age to buy.Age in line 15 of the code worked.
