C# 在长字符串上每隔一个逗号拆分字符串

Question

我有一个看起来像这样的字符串:

string  a =  "Stuff, another thing, random stuff, snuff, Pigs are wierd, sick, Cats are dangerous, they will kill you, Cows produce milk, but horses don't"

所以我的目标是检索一个看起来像这样的字符串

string output =  "Stuff, another thing
                  Random stuff, snuff
                  Pigs are wierd, sick
                  Cats are dangerous, they will kill you
                  Cows produce milk, but horses don't"

尝试使用正则表达式来做到这一点，但如果字符串以一种好的方式更长，则无法真正让它正确分组。

string[] output = Regex.Split(a, "^([^,]+(?:,[^,]+){1})");

有什么建议吗？

将其沿所有逗号拆分，然后重新组合成以逗号分隔的对。

using System;

public class Program
{
    public static void Main()
    {
        string  a =  "Stuff, another thing, random stuff, snuff, Pigs are wierd, sick, Cats are dangerous, they will kill you, Cows produce milk, but horses don't";
        string[] splittedStrings = a.Split(new[]{", "}, StringSplitOptions.None);
        for (var i = 0; i < splittedStrings.Length / 2; i++)
        {
            Console.WriteLine(splittedStrings[i*2] + ", " + splittedStrings[i*2 + 1]);
        }

        if(splittedStrings.Length % 2 == 1)
        {
            Console.WriteLine(splittedStrings[splittedStrings.Length-1]);
        }
    }
}
