如何格式化字符串 [英] How to format a string

问题描述

我需要格式化字符串.

源字符串:123332qw332w2

结果字符串:123-332-qw3-32w2

有什么简单的方法可以像处理数字(String.Format)一样?


格式不固定.它在配置文件中给出，例如xxx-xxxxx-xxxxx.

可以以xxx-xxxxx-xxx之类的格式存储.一组值采用如上所述的单一格式.我需要格式化应基于上述给定的格式.格式xxx-xxxxx-xxx将成为可配置的.希望这能解释

Hi,

I need to format a string.

Source string: 123332qw332w2

Result string: 123-332-qw3-32w2

Is there any easy way to do it as we do for numbers(String.Format)?


Format is not fixed. It is given in the config file like xxx-xxxxx-xxxxx.

That can be stored in some format like xxx-xxxxx-xxx. A group of values take a single format like above.. I need the formatting should be based on a given format like above. Format xxx-xxxxx-xxx will be made configurable. Hope this explains

尝试一下

public void stringFormat()
       {
           var str = "123332qw332w2";
           var newStr = "";
           var increment = 1;
           for (int index = 3; index < 15; index += (3 + increment))
           {
               newStr = str.Insert(index, "-");
               str = newStr;

           }
             newStr;//final output
       }

它将显示您想要的输出
