如何用“ XX XXX”代替“ XX，XXX”？

Question

I need to replace string like "XX,XXX" with "XX XXX". The string "XX,XXX" is in another string, eg:

"-1299-5,"XXX,XXXX",trft,4,0,10800"

The string is fetched from a text file. I want to split the string by ",". But the comma in the substring led to the wrong result.

The X represents a char. I think regex can help, who can give me the right regex expression.

Answer 1

This expression,

(.*"[^,]*),([^,]*".*)

with a replacement of $1 $2 might work.

Demo

Example

using System;
using System.Text.RegularExpressions;

public class Example
{
    public static void Main()
    {
        string pattern = @"(.*""[^,]*),([^,]*"".*)";
        string substitution = @"\1 \2";
        string input = @"-1299-5,""XXX,XXXX"",trft,4,0,10800";
        RegexOptions options = RegexOptions.Multiline;

        Regex regex = new Regex(pattern, options);
        string result = regex.Replace(input, substitution);
    }
}

Answer 2

Simply, use 'Replace' to replace char from your string.

 var test = "XXX,XXXX";
 var filtered = test.Replace(',', ' ');  
 Console.WriteLine(filtered); 

Output :

XXX XXXX
