在c#中将数据写入csv文件有什么问题？

using System;
using System.IO;
using System.Text;

class Program
{
    static void Main()
    {
        string filePath = "data.csv";
        string[] data = { "Name", "Age", "City" };
        string[] row1 = { "Alice", "30", "New York" };
        string[] row2 = { "Bob", "25", "Los Angeles" };

        using (StreamWriter writer = new StreamWriter(filePath, false, Encoding.UTF8))
        {
            // 写入表头
            writer.WriteLine(string.Join(",", data));

            // 写入数据行
            writer.WriteLine(string.Join(",", row1));
            writer.WriteLine(string.Join(",", row2));
        }

        Console.WriteLine("CSV文件已成功写入。");
    }
}
