拆分字符串,同时保留用引号括起来的值(.NET)

using System;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        string input = "apple, \"banana, cherry\", date, \"elderberry, fig\"";
        List<string> result = SplitString(input);
        
        foreach (string item in result)
        {
            Console.WriteLine(item);
        }
    }
    
    public static List<string> SplitString(string input)
    {
        List<string> result = new List<string>();
        bool insideQuotes = false;
        int startIndex = 0;
        
        for (int i = 0; i < input.Length; i++)
        {
            if (input[i] == '\"')
            {
                insideQuotes = !insideQuotes;
            }
            
            if (input[i] == ',' && !insideQuotes)
            {
                string item = input.Substring(startIndex, i - startIndex).Trim();
                result.Add(item);
                startIndex = i + 1;
            }
        }
        
        // 添加最后一个项目
        string lastItem = input.Substring(startIndex).Trim();
        result.Add(lastItem);
        
        return result;
    }
}

apple
