如何防止被零除？ [英] How to prevent division by zero?

问题描述

 广告= ads.Where（X =>（x.Amount  -  x.Price）/（x.Amount / 100）GT = filter.Persent）; 
  

如果x.Amount == 0我有错误所遇到的零误差鸿沟。

像我这样的要求是为了避免

更新：

这帮助，但我不喜欢这个决定：

 广告= ads.Where （X =>（x.Amount  -  x.Price）/（（x.Amount / 100）== 0 0.1：（x.Amount / 100））> = filter.Persent）; 
  

有另一种方式？

解决方案

 广告= ads.Where（X => x.Amount = 0&放大器;&安培;！
（x.Amount  -  x.Price ）/（x.Amount / 100）> = filter.Persent）; 
  

ads = ads.Where(x => (x.Amount - x.Price) / (x.Amount / 100) >= filter.Persent);

if x.Amount == 0 I have error "Divide by zero error encountered."

like me in this request is to avoid?

update:

this helped, but I do not like the decision:

ads = ads.Where(x => (x.Amount - x.Price) / ((x.Amount / 100)==0?0.1:(x.Amount / 100)) >= filter.Persent);

there is another way?

解决方案

ads = ads.Where(x => x.Amount != 0 &&
                    (x.Amount - x.Price) / (x.Amount / 100) >= filter.Persent);
