sorry i don't speak very well in English..

i have a string and i want to split into 2 tokens + remove the second ',' i want to parse this with regex.

i tested this but not work:

("[^"]+","[^"]+"),

a string like "a","b" most not break

Doesn't this work?

var splittedValues = yourString.Split(',');

You can use the .Net built in method String.Split()

String[] splitString = "foo,bar,meow".Split(',');

you should look at TextFieldParser Class to handle this

working example that give the input that you provided and give you the output requested

    using Microsoft.VisualBasic.FileIO;
    using System;
    using System.Collections.Generic;
    using System.IO;
    using System.Text;

    namespace ConsoleApplication1
    {
        class Program
        {
            static void Main(string[] args)
            {
                var test = "\"foo bar\",\" \",\"boooo\",\" baz\"";
                var result = new List<string>();

                using (var data = new MemoryStream(Encoding.UTF8.GetBytes(test)))
                using (var parser = new TextFieldParser(data))
                {
                    parser.Delimiters = new string[] {","};
                    parser.TrimWhiteSpace = false;

                    var fields = parser.ReadFields();
                    int i = 0;
                    foreach (var field in fields)
                    {
                        if ((i % 2) == 0)
                        {
                            result.Add(string.Format("\"{0}\"", (string.IsNullOrWhiteSpace(field) ? field : field.Trim())));
                        }
                        else
                        {
                            result[result.Count - 1] += string.Format(",\"{0}\"", (string.IsNullOrWhiteSpace(field) ? field : field.Trim()));
                        }
                        i++;
                    }
                }

                foreach (var item in result)
                {
                    Console.WriteLine(item);
                }

                Console.ReadKey(false);
            }
        }
    }
