获取字符串中某个索引之后的第一个检测到的空间的索引 [英] Get index of first detected space after a certain index in a string

问题描述

在要格式化的字符串中(主要是用不同的符号替换char以在UI上进行渲染测试)，我必须检测％，然后从此％char中跳过所有char util的第一个空格，并且必须对其中的所有实例重复此操作字符串.

In a string to format (mostly to replace chars with different symbols for rendering test on UI), I have to detect % and then skip all chars util first space from this % char and it has to be repeated for all instances in the string.

例如 abcd％1 $ s efgh％2 $ d ijkl .在此字符串中，我必须获取％的索引，然后从中找到第一个空格的索引.基本上，我必须跳过此％1 $ s &％2 $ d 是某种格式的占位符.我希望，我不会在这里提出复杂的内容.

E.g. abcd%1$s efgh %2$d ijkl .In this string, I have to get index of % and then find index of first space from that. Basically, I have to skip this %1$s & %2$d which are some sort of formatting placeholders. I hope, I am not putting it in complex way here.

推荐答案

您可以轻松获得它，只需在第一个百分号前获取索引，然后利用该索引从那里找到第一个空格:

You can get that pretty easily, just grab the index if the first percent sign and then leverage that index to find the first space from there:

var start = myString.IndexOf("%");
var spaceIndex = myString.IndexOf(" ", start)

当然，myString的值是您在问题中表示的字符串.

of course the value of myString is the string you represented in your question.
