检测文件的每一行如何以C#结尾

using System;
using System.IO;

class Program
{
    static void Main(string[] args)
    {
        string filePath = "path/to/your/file.txt"; // 文件路径

        try
        {
            // 读取文件
            using (StreamReader sr = new StreamReader(filePath))
            {
                int lineCount = 0;
                string line;

                // 逐行检测
                while ((line = sr.ReadLine()) != null)
                {
                    lineCount++;
                    if (line.Trim().EndsWith("C#"))
                    {
                        Console.WriteLine($"Line {lineCount}: {line}");
                        // 可以根据需求进一步处理符合条件的行
                    }
                }
            }
        }
        catch (IOException e)
        {
            Console.WriteLine("An error occurred while reading the file: " + e.Message);
        }
    }
}
