如果字符串是不可变的，那我怎么修剪它们呢?

问题描述

所以我只是浪费了大约30分钟，试图弄清原因:

myString.Replace("5之6"，"3之5")

我不会更改我的字符串...直到我读到有关字符串不可变并且需要创建新字符串的文章.

myNewString = myString.Replace("5之6"，"5之3")- -一切工作都很酷..

好吧..我知道，字符串是堆上的引用-无法更改...等等等等...

但后来我开始考虑LTring和RTrim ...我知道我以前使用过这些更改字符串而不创建新的string或stringBuilders.

请问有人能启发我吗?

So I just wasted about 30 minutes trying to figure out why:

myString.Replace("5 of 6", "3 of 5")

would not CHANGE my string... until I read a post about strings being immutable and that I needed to create a new string.

myNewString = myString.Replace("5 of 6", "3 of 5")   --  everything worked cool..

OK FINE.. I understand, Strings are references on the heap - cant be changed...blah blah...

But then I began to think about LTring and RTrim... I KNOW I have used those before to change strings without creating new strings or stringBuilders.

Can someone enlighten me please?
