毫无意义的分号会影响性能吗? [英] Will a pointless semicolon have any performance impact?

问题描述

有时，我注意到我在语句后添加了一个额外的 ;.

Sometimes, I notice I add an additional ; after a statement.

示例:

Console.WriteLine("meow");;

这会影响我的应用程序的性能吗?具体来说，我想知道 C#.

Will that effect the performance in my app? Specifically, I am wondering about C#.

推荐答案

无；它不会影响编译器生成的 IL 代码.

None whatsoever; it will not impact the IL code that the compiler generates.

然而，它可能会对任何必须维护您的代码的同事产生性能影响...

It may however have a performance impact on any coworkers who have to maintain your code...
