如何在c#中出现某个字符串时停止读取文件

using System;
using System.IO;

class Program
{
    static void Main()
    {
        string filePath = "path/to/your/file.txt";
        string stopString = "stop";

        using (StreamReader reader = new StreamReader(filePath))
        {
            string line;
            while ((line = reader.ReadLine()) != null)
            {
                Console.WriteLine(line);

                if (line.Contains(stopString))
                {
                    break;
                }
            }
        }
    }
}
