如何使用C#处理CSV文件中的换行符？

using System;
using System.IO;
using System.Linq;

class Program
{
    static void Main()
    {
        string filePath = @"path\to\your\file.csv";
        string[] lines = File.ReadAllLines(filePath);

        foreach (var line in lines)
        {
            // 处理换行符
            string cleanedLine = ProcessNewLines(line);
            Console.WriteLine(cleanedLine);
        }
    }

    static string ProcessNewLines(string line)
    {
        // 假设字段用双引号包围
        string[] fields = line.Split(new char[] { ',', '"' }, StringSplitOptions.None);
        var processedFields = new string[fields.Length / 2];
        int index = 0;

        for (int i = 0; i < fields.Length; i += 2)
        {
            string fieldValue = fields[i + 1];
            if (i + 2 < fields.Length && fields[i + 2] == "\"")
            {
                fieldValue += "," + fields[i + 3];
                i += 3;
            }
            processedFields[index++] = fieldValue;
        }

        return string.Join(",", processedFields);
    }
}
