How to split this string

1014,'0,1031,1032,1034,1035,1036',0,0,1,1,0,1,0,-1,1

and get this string array as result

1014
'0,1031,1032,1034,1035,1036'
0

Answer 1

I believe that this regex should give you what you are looking for:

('(?:[^']|'')*'|[^',\r\n]*)(,|\r\n?|\n)?

EDIT:

Quick code snippet on how it might work:

 var rx = new Regex("('(?:[^']|'')*'|[^',\r\n]*)(,|\r\n?|\n)?");
 var text= "1014,'0,1031,1032,1034,1035,1036',0,0,1,1,0,1,0,-1,1";

 var matches = rx.Matches(text);

 foreach (Match match in matches)
 {
     System.Console.WriteLine(match.Groups[1].ToString());
 }

Answer 2

This code is not pretty at all, but it works. :) (Does not work with multiple "strings" within the string.)

void Main()
{
    string stuff = "1014,'0,1031,1032,1034,1035,1036',0,0,1,1,0,1,0,-1,1";
    List<string> newStuff = new List<string>();

    var extract = stuff.Substring(stuff.IndexOf('\''), stuff.IndexOf('\'', stuff.IndexOf('\'') + 1) - stuff.IndexOf('\'') + 1);
    var oldExtract = extract;
    extract = extract.Replace(',',';');
    stuff = stuff.Replace(oldExtract, extract);
    newStuff.AddRange(stuff.Split(new[] {','}));
    var newList = newStuff;
    for(var i = 0; i < newList.Count; i++)
        newList[i] = newList[i].Replace(';',',');
    // And newList will be in the format you specified, but in a list..
}

Answer 3

try this,

string line ="1014,'0,1031,1032,1034,1035,1036',0,0,1,1,0,1,0,-1,1" ;
var values = Regex.Matches(line, "(?:'(?<m>[^']*)')|(?<m>[^,]+)");
foreach (Match value in values) {
  Console.WriteLine(value.Groups["m"].Value);
}

Answer 4

首先在' （单引号）上分割字符串，然后使用comma （，）。

Answer 5

You don't need a parser, you don't need Regex. Here's a pretty simple version that works perfectly:

var splits = input
            .Split('\'')
            .SelectMany(
                (s,i) => (i%2==0) 
                ? s.Split(new[]{','}, StringSplitOptions.RemoveEmptyEntries) 
                : new[]{ "'" + s + "'"}
            );

This is exactly what @AVD + @Rawling described ... Split on ' , and split only "even" results, then combine.

using System;
using System.IO;
using Microsoft.VisualBasic.FileIO; //Microsoft.VisualBasic.dll

public class Sample {
    static void Main(){
        string data = "1014,'0,1031,1032,1034,1035,1036',0,0,1,1,0,1,0,-1,1";
        string[] fields = null;
        data = data.Replace('\'', '"');
        using(var csvReader = new TextFieldParser(new StringReader(data))){
            csvReader.SetDelimiters(new string[] {","});
            csvReader.HasFieldsEnclosedInQuotes = true;
            fields = csvReader.ReadFields();
        }
        foreach(var item in fields){
            Console.WriteLine("{0}",item);
        }
    }
}
