用法

示例：

Example:

var rand = new Random();
var rule = new Rule()
{
   RuleExpressionType = RuleExpressionType.Lambda,
   RuleExpression = $"price < expectPrice",
   FaildMessage = "股价报价为：#(price)#，预期价位为：#(expectPrice)#，股价不匹配，取消购买",
   SucessMessage = "股价报价为：#(price)#，预期价位为：#(expectPrice)#， 当前余额：#(totalMoney)#，可买入，购买系数：#rate#（余额的比例），买入数量：#(Math.round(totalMoney*rate/price))#，买入后余额：#(totalMoney-Math.round(totalMoney*rate/price)*price)#",
   RuleName = "判断股价，价格匹配就买入",
};
var input = new Dictionary<string, object>();
input["price"] = rand.Next(1, 100);
input["rate"] = rand.NextDouble();
input["expectPrice"] = rand.Next(1, 100);
input["totalMoney"] = rand.Next(1, 100) * rand.Next(2, 200);

var result = (ruleEngine.Execute(rule, input));

返回结果（需要手动序列化）：
