如何在 if 条件下应用组合技术

How to apply combine technique with if condition

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;
        }

评论描述的业务逻辑,要结合if (IsGoldCustomer() && LessThan(24)) 和if (!IsGoldCustomer() &&LessThan(48)) 条件。有什么建议吗?

下面两个if条件都修改了,但是修改不满足我的要求

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

甚至:

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