c# - 简化条件if语句c#

Question

我有一个 if 语句，变得有点麻烦。我想知道是否有更好的方法来处理多个类似的 if 语句，例如组合成一个或使用不同的条件语句，例如 while 或 do 循环。任何建议表示赞赏。

if (options.OpenCloseOverridesOptions != null && !options.OpenCloseOverridesOptions.AreEqual(OpenCloseOverridesOptions))
            return false;

        if (options.DeliveryOpenCloseOverridesOptions != null && !options.DeliveryOpenCloseOverridesOptions.AreEqual(DeliveryOpenCloseOverridesOptions))
            return false;

        if (options.PickupOpenCloseOverridesOptions != null && !options.PickupOpenCloseOverridesOptions.AreEqual(PickupOpenCloseOverridesOptions))
            return false;

        if (options.PickupServiceWindowOverridesOptions != null && !options.PickupServiceWindowOverridesOptions.AreEqual(PickupServiceWindowOverridesOptions))
            return false;

        if (options.DeliveryServiceWindowOverridesOptions != null && !options.DeliveryServiceWindowOverridesOptions.AreEqual(DeliveryServiceWindowOverridesOptions))
            return false;

        if (options.ServiceWindowOverridesOptions != null && !options.ServiceWindowOverridesOptions.AreEqual(ServiceWindowOverridesOptions))
            return false;

        if (options.LineItemsOptions != null && !options.LineItemsOptions.AreEqual(LineItemsOptions))
            return false;

简而言之，我基本上是在检查一个对象是否为 null，如果不为 null，则使用扩展方法来确定一个相似的对象是否相等。 (我没有覆盖 isEquals 和 getHashCode )。如果对象为 null，我无法调用 areEquals 扩展方法，因此有必要进行检查。

如果要返回bool可以直接返回条件

我们可以使用另一个技能 ( De Morgan's laws ) 让!放入语句中，将所有逻辑颠倒过来，让代码更清晰。

return  
    (options.OpenCloseOverridesOptions == null || options.OpenCloseOverridesOptions.AreEqual(OpenCloseOverridesOptions)) &&
    (options.DeliveryOpenCloseOverridesOptions == null || options.DeliveryOpenCloseOverridesOptions.AreEqual(DeliveryOpenCloseOverridesOptions)) &&
    (options.PickupOpenCloseOverridesOptions == null || options.PickupOpenCloseOverridesOptions.AreEqual(PickupOpenCloseOverridesOptions))&&
    (options.PickupServiceWindowOverridesOptions == null || options.PickupServiceWindowOverridesOptions.AreEqual(PickupServiceWindowOverridesOptions) &&
    (options.DeliveryServiceWindowOverridesOptions == null || options.DeliveryServiceWindowOverridesOptions.AreEqual(DeliveryServiceWindowOverridesOptions)&&
    (options.ServiceWindowOverridesOptions == null || options.ServiceWindowOverridesOptions.AreEqual(ServiceWindowOverridesOptions)&&
    (options.LineItemsOptions == null || options.LineItemsOptions.AreEqual(LineItemsOptions)
