Question

我正在通过计算为var分配一个值，但它显示语法错误我已经看到所有括号仍然给出错误，这里是我的代码。

appDelegate.Same_Vaccination_Cost_Treatment_Annually_With_Guarantee =（（appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee - 5000）/ appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee）* （（appDelegate.Cost_Treatment_SevereEI * appDelegate.Same_Vaccination_SevereEI_Annually）+ （appDelegate.Cost_Treatment_ModerateEI * appDelegate.Same_Vaccination_ModerateEI_Annually）+ （appDelegate.Cost_Treatment_MildEI * appDelegate.Same_Vaccination_MildEI_Annually））））* appDelegate.Same_Vaccination_Horses_Per_Premise;

Answer 1

根据您的代码： -

    float Same_Vaccination_Cost_Treatment_Annually_With_Guarantee;
    float Cost_Treatment_SevereEI;
    float Same_Vaccination_SevereEI_Annually;
    float Cost_Treatment_MildEI;
    float Same_Vaccination_MildEI_Annually;
    float Same_Vaccination_Horses_Per_Premise;
    float Same_Vaccination_Cost_Treatment_Annually_No_Guarantee;
    float Cost_Treatment_ModerateEI;
    float Same_Vaccination_ModerateEI_Annually;

Same_Vaccination_Cost_Treatment_Annually_With_Guarantee=(((Same_Vaccination_Cost_Treatment_Annually_No_Guarantee - 5000) / Same_Vaccination_Cost_Treatment_Annually_No_Guarantee) * (((Cost_Treatment_SevereEI * Same_Vaccination_SevereEI_Annually) + (Cost_Treatment_ModerateEI * Same_Vaccination_ModerateEI_Annually) + (Cost_Treatment_MildEI * Same_Vaccination_MildEI_Annually)) * Same_Vaccination_Horses_Per_Premise));

你也可以把方法放在： -

Same_Vaccination_Cost_Treatment_Annually_With_Guarantee=((Same_Vaccination_Cost_Treatment_Annually_No_Guarantee - 5000) / Same_Vaccination_Cost_Treatment_Annually_No_Guarantee) * ((Cost_Treatment_SevereEI * Same_Vaccination_SevereEI_Annually) + (Cost_Treatment_ModerateEI * Same_Vaccination_ModerateEI_Annually) + (Cost_Treatment_MildEI * Same_Vaccination_MildEI_Annually)) * Same_Vaccination_Horses_Per_Premise;

Answer 2

如果您使用完全相同的

    appDelegate.Same_Vaccination_Cost_Treatment_Annually_With_Guarantee=((appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee - 5000) / appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee) * ((appDelegate.Cost_Treatment_SevereEI * appDelegate.Same_Vaccination_SevereEI_Annually) + (appDelegate.Cost_Treatment_ModerateEI * appDelegate.Same_Vaccination_ModerateEI_Annually) + (appDelegate.Cost_Treatment_MildEI * appDelegate.Same_Vaccination_MildEI_Annually)))) * appDelegate.Same_Vaccination_Horses_Per_Premise;

然后你有2个额外的支撑

试

    appDelegate.Same_Vaccination_Cost_Treatment_Annually_With_Guarantee=((appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee - 5000) / appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee) * ((appDelegate.Cost_Treatment_SevereEI * appDelegate.Same_Vaccination_SevereEI_Annually) + (appDelegate.Cost_Treatment_ModerateEI * appDelegate.Same_Vaccination_ModerateEI_Annually) + (appDelegate.Cost_Treatment_MildEI * appDelegate.Same_Vaccination_MildEI_Annually)) * appDelegate.Same_Vaccination_Horses_Per_Premise;

Answer 3

appDelegate.Same_Vaccination_Cost_Treatment_Annually_With_Guarantee =（（appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee - 5000）/ appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee）*（（* appDelegate.Cost_Treatment_SevereEI appDelegate.Same_Vaccination_SevereEI_Annually）+（appDelegate.Cost_Treatment_ModerateEI * appDelegate.Same_Vaccination_ModerateEI_Annually）+（appDelegate.Cost_Treatment_MildEI * appDelegate.Same_Vaccination_MildEI_Annually ））* appDelegate.Same_Vaccination_Horses_Per_Premise;

这会奏效。你使用了太多括号。
