Question

我正在尝试做IF（SOMETHING＆amp;＆amp; NOT）或（SOMETHING＆amp;＆amp; NOT）...但它不起作用，你能看出我做错了吗？

if (MyBeam.Position.Rotation == Position.RotationEnum.FRONT &&
!(MyBeam.Profile.ProfileString.Contains("RHS")
|| MyBeam.Profile.ProfileString.Contains("CHS")
|| MyBeam.Profile.ProfileString.Contains("MET")
|| MyBeam.Profile.ProfileString.Contains("SHS")

||

(MyBeam.Position.Rotation == Position.RotationEnum.BACK &&
!(MyBeam.Profile.ProfileString.Contains("RHS")
|| MyBeam.Profile.ProfileString.Contains("CHS")
|| MyBeam.Profile.ProfileString.Contains("MET")
|| MyBeam.Profile.ProfileString.Contains("SHS")))))

忽略对API的引用，但我相信它仍然有意义。

你的括号错了。这应该工作：

if ((MyBeam.Position.Rotation == Position.RotationEnum.FRONT &&
     !(MyBeam.Profile.ProfileString.Contains("RHS") || 
       MyBeam.Profile.ProfileString.Contains("CHS") || 
       MyBeam.Profile.ProfileString.Contains("MET") || 
       MyBeam.Profile.ProfileString.Contains("SHS"))) ||
    (MyBeam.Position.Rotation == Position.RotationEnum.BACK &&
     !(MyBeam.Profile.ProfileString.Contains("RHS") || 
       MyBeam.Profile.ProfileString.Contains("CHS") || 
       MyBeam.Profile.ProfileString.Contains("MET") || 
       MyBeam.Profile.ProfileString.Contains("SHS"))))

那就是说，这是非常难以理解的。尝试将其中一些组合成变量，例如：

bool profileCheck = MyBeam.Profile.ProfileString.Contains("RHS") || MyBeam.Profile.ProfileString.Contains("CHS") || 
                    MyBeam.Profile.ProfileString.Contains("MET") || MyBeam.Profile.ProfileString.Contains("SHS");

if ((MyBeam.Position.Rotation == Position.RotationEnum.FRONT && !profileCheck) ||
    (MyBeam.Position.Rotation == Position.RotationEnum.BACK && !profileCheck))

在这种形式中，我可以看到它可以简化：

if (!profileCheck && (MyBeam.Position.Rotation == Position.RotationEnum.FRONT || MyBeam.Position.Rotation == Position.RotationEnum.BACK))

你是说你希望轮换是前面还是前面而你不想要RHS但是接受CHS，MET，SHS？

if ((MyBeam.Position.Rotation == Position.RotationEnum.FRONT || MyBeam.Position.Rotation == Position.RotationEnum.BACK) &&
(
!MyBeam.Profile.ProfileString.Contains("RHS")
|| MyBeam.Profile.ProfileString.Contains("CHS")
|| MyBeam.Profile.ProfileString.Contains("MET")
|| MyBeam.Profile.ProfileString.Contains("SHS")
)
)

或者如果它是你说你想要旋转是前面还是后面而你不想要任何RHS，CHS，MET，SHS？

if ((MyBeam.Position.Rotation == Position.RotationEnum.FRONT || MyBeam.Position.Rotation == Position.RotationEnum.BACK) &&
 !(
MyBeam.Profile.ProfileString.Contains("RHS")
|| MyBeam.Profile.ProfileString.Contains("CHS")
|| MyBeam.Profile.ProfileString.Contains("MET")
|| MyBeam.Profile.ProfileString.Contains("SHS")
)
)

Answer 3

你的不是部分似乎不正确。您需要NOT所有OR条件

if ((MyBeam.Position.Rotation == Position.RotationEnum.FRONT || MyBeam.Position.Rotation == Position.RotationEnum.BACK) &&
!((MyBeam.Profile.ProfileString.Contains("RHS")
|| MyBeam.Profile.ProfileString.Contains("CHS")
|| MyBeam.Profile.ProfileString.Contains("MET")
|| MyBeam.Profile.ProfileString.Contains("SHS"))

IF AND OR C＃的语法是什么
