如何申請使用，如果條件

Question

C＃代碼的語法是波紋管相結合的技術

 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; 
     } 

評論描述業務邏輯，要合併，如果（IsGoldCustomer（）& &每種不超過（24）），如果（！IsGoldCustomer（） & & LessThan（48））條件。有什麼建議如何？

修改既如果條件波紋管，但修改不滿足我的要求。

//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);
