如何应用与if条件的组合技术

Question

C# 代码语法如下

        public void Cancel()
        {
            // If reservation already started throw exception
            if (DateTime.Now > From)
            {
                throw new InvalidOperationException("It's too late to cancel.");
            }
//for gold customer IsCanceled= false
            if (IsGoldCustomer() && LessThan(24))
            {
                IsCanceled = false;
            }
//for not gold customer IsCanceled= true
            if (!IsGoldCustomer() &&LessThan(48))
            {
                IsCanceled = true;
            }
        }
        private bool IsGoldCustomer()
        {
            return Customer.LoyaltyPoints > 100;
        }
        private bool LessThan(int maxHours)
        {
            return (From - DateTime.Now).TotalHours < maxHours;
        }

注释描述了业务逻辑，想要组合 if (IsGoldCustomer(( && LessThan(24(( 和 if (！IsGoldCustomer(( &&LessThan(48(( 条件。有什么建议吗？

如果条件为波纹管，则修改了两者，但修改不符合我的要求。

//for gold customer IsCanceled= false
            IsCanceled = !(IsGoldCustomer() && LessThan(24));
//for not gold customer IsCanceled= true
            IsCanceled = !IsGoldCustomer() &&LessThan(48);

Answer 1

IsCancelled = IsGoldCustomer()? !LessThan( 24 ) : !LessThan( 48 );

甚至：

IsCancelled = !LessThan( IsGoldCustomer()? 24 : 48 );
