用单引号替换逗号但忽略逗号分隔的字符串 [英] Replace commas in single quotes but ignore comma separated string

问题描述

您好，

我想使用正则表达式替换带空格的单引号中的逗号，但忽略逗号分隔的字符串。

<有没有人知道怎么做C＃？

示例：

原始字符串：

" abc，'this，demo'，foo，'hello，world'，bar ,,"

更换引号中的逗号后，结果为：

" abc，'this demo'，foo ，'hello world'，bar ,,"

解决方案

选中：

 var example =" abc，'this，demo'，foo，'hello，world'，bar ,," ;; 
 var result = Regex.Replace（例如，@"，（？= [^'] *'（[^'] *'[^'] *'）* [^'] * 

）"，""）;

Console.WriteLine（示例）;
Console.WriteLine（结果）;

Hello,

I would like to use regular expression to replace commas in single quotes with spaces, but ignore comma separated string.

Does anyone know how to do in C#?

Example:

Original string:

"abc,'this,demo',foo,'hello,world', bar, ,"

After replacing the commas in quotes, the result is:

"abc,'this demo',foo,'hello world', bar, ,"

解决方案

Check this:

var example = "abc,'this,demo',foo,'hello,world', bar, ,";
var result = Regex.Replace( example, @",(?=[^']*'([^']*'[^']*')*[^']*

)", " " ); Console.WriteLine( example ); Console.WriteLine( result );
