我已经成功地从外部文件中读取并显示了我的代码。我还获得了一个简单的Caesar移位的代码。我只是不知道如何在文件中读取我的代码，然后执行凯撒移位并在凯撒移位后显示输出，有人能帮忙吗。这是我的代码：

using System;
using System.IO; 
class Shift
{
    public static void Main(string [] args)
    {
        //Read in code to shift from text file.
        string file = @"txt"; //I have a file linked here
        string text = File.ReadAllText(file);
        //Show original unshifted code. 
        System.Console.WriteLine("Original text reads: 'n'n{0}", text);
        //Show text after shift. 
        Console.WriteLine("The shifted code is: 'n'n{1}", b);
    //Start Caesar Shift code as a seperate method.  
    }
    public static string Caesar(string value, int shift)
    {  
    char[] buffer = value.ToCharArray();
    for (int i = 0; i < buffer.Length; i++)
    {
        char letter = buffer[i];
        letter = (char)(letter + shift);
        if (letter > 'z')
        {
        letter = (char)(letter - 26);
        }
        else if (letter < 'a')
        {
        letter = (char)(letter + 26);
        }
        // Store shift. 
        buffer[i] = letter;
    }
    return new string(buffer);
  }
  //Add number to shift text. 
   public static void Second()
    {
    string a = text;
    string b = Caesar(a, 18); 
    }
}

读入外部文件，然后在Caesar移位后显示

您就快到了。查看下面代码段中的最后一个Console.WriteLine。

public static void Main(string[] args)
{
    //Read in code to shift from text file.
    var file = @"txt"; //I have a file linked here
    var text = File.ReadAllText(file);
    //Show original unshifted code. 
    Console.WriteLine("Original text reads: 'n'n{0}", text);
    //Show text after shift. 
    Console.WriteLine("The shifted code is: 'n'n{0}", Caesar(text, 18));
}
