还记得C#中.txt文件的最后一个位置吗？

using System;
using System.IO;

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

        using (FileStream fileStream = new FileStream(filePath, FileMode.Open))
        {
            // 将文件指针移动到文件末尾
            fileStream.Seek(0, SeekOrigin.End);

            // 获取当前文件指针的位置
            long lastPosition = fileStream.Position;

            Console.WriteLine("The last position of the .txt file is: " + lastPosition);
        }
    }
}
