Question

你目前有这个读取txt文件的代码。我想让它向后读取文件。它目前显示“向后运行句子直到令人难以置信” 我想让它显示“在句子向后运行之前不要担心”

        // Read sentences ...
        while (!infile.EndOfStream)
        {
            // Read a line from the file, as a whole string
            string line = infile.ReadLine();
            // Split string into 'words', separated by spaces
            string[] words = line.Split(' ');

            // Loop through each 'word' found
            for (int i = 0; i < words.Length; i++)
            {
                // Output current word
                Console.Write(words[i]);
                // Output a space between every word, except for the last one
                if (i <= words.Length + 1)
                {
                    Console.Write(" ");
                }
            }
            // Output a newline chatracter at the end of the sentence
            Console.WriteLine();
        }
        infile.Close(); // Be a tidy kiwi

        // Wait for user to have read the output
        Console.WriteLine();
        Console.Write("<Press enter to finish>");
        Console.ReadLine();
    }
}

}

获得原始单词数组后 - 您可以简单地将其反转：

 string[] words = line.Split(' ');
 Array.Reverse(words, 0, words.Length);
