Question

目前我的程序只打印文本文件中的最后274行。如何在控制台上打印整个文本文件（大约500行）？

以下是我的代码：

using System;

namespace InsertTextFileSample
{

  class Program
  {

    static void Main(string[] args)
    {
        // Example #2
        // Read each line of the file into a string array. Each element
        // of the array is one line of the file.
        string TextFile = Console.ReadLine();
        string[] lines = System.IO.File.ReadAllLines(@"C:\Users\Firzanah\Downloads\"+TextFile);

        // Display the file contents by using a foreach loop.
        System.Console.WriteLine("Contents of nvram.txt = /n");
        foreach (string line in lines)
        {
            // Use a tab to indent each line of the file.
            Console.WriteLine("\t" + line);
        }

        // Keep the console window open in debug mode.
        Console.WriteLine("Press any key to exit.");
        System.Console.ReadKey();
    }
  }
}

使用File.ReadAllLines一次将行读入数组。尝试逐行阅读文件：

using System;

namespace InsertTextFileSample
{
    class Program
    {

        static void Main(string[] args)
        {
            string TextFile = Console.ReadLine();
            string path = @"C:\Users\Firzanah\Downloads\" + TextFile;
            string line;
            var fileReader =
               new System.IO.StreamReader(path);

            Console.WriteLine("Contents of nvram.txt = /n");
            while ((line = fileReader.ReadLine()) != null)
            {
                Console.WriteLine("\t" + line);
            }

            fileReader.Close();
            Console.ReadKey();
        }
    }
}

如何在控制台中从文本文件中打印更多行？
