修剪字符串并将其转换为小写的最快方法 [英] Fastest way to trim a string and convert it to lower case

问题描述

我编写了一个用于处理字符串的类，但遇到了以下问题：传入的字符串在字符串的开头和结尾可能带有空格。

I've written a class for processing strings and I have the following problem: the string passed in can come with spaces at the beginning and at the end of the string.

我需要修剪字符串中的空格并将其转换为小写字母。到目前为止，我的代码是：

I need to trim the spaces from the strings and convert them to lower case letters. My code so far:

var searchStr = wordToSearchReplacemntsFor.ToLower();
        searchStr = searchStr.Trim();

在 StringBuilder 。问题在于，此类应该尽可能快地处理许多字符串。因此，我不想为课程处理的每个字符串创建2个新字符串。

I couldn't find any function to help me in StringBuilder. The problem is that this class is supposed to process a lot of strings as quickly as possible. So I don't want to be creating 2 new strings for each string the class processes.

如果不可能，我将更深入地介绍处理算法。

If this isn't possible, I'll go deeper into the processing algorithm.
