try catch子句会影响性能吗? [英] does try catch clause affect performance?

问题描述

如果在 try 块中没有引发异常， try/catch 是否会影响性能?
try/catch/finally 怎么样?

does try/catch affects performance if no exception thrown in try block?
how about try/catch/finally?

推荐答案

try/catch 和 try/catch/finally 都不会在很大程度上影响性能.当然，创建的异常 do 会影响性能(即是否捕获到异常)

Neither try/catch nor try/catch/finally affects performance to any significant degree. Exceptions being created do affect performance, of course (and that is whether they are caught, or not)

>尝试/捕获块会影响性能什么时候不抛出异常?
