c# - 将字符转换为 Ascii

Question

我一直在创建一个代码破解软件，我需要将文本文件中的字符转换为 ascii 数字以允许转换。我在下面留下了我的代码，但有人可以解释一下我该怎么做吗？

using System;
using System.IO;

namespace CipherDecoder
{
    class Program
    {
        static void Main(string[] args)
        {
            string fileText = @"C:/Users/Samuel/Documents/Computer_Science/PaDS/caeserShiftEncodedText";

            string cipherText = File.ReadAllText(fileText);

            string output = @"C:\\Users\Samuel\Documents\Computer_Science\PaDS\output.txt\";

            char[] cipherChars = new char[691];

            int j = 0;

            foreach (char s in cipherText)
            {
                cipherChars[j] = s;

                j++;
            }

            for(int i = 0; i < cipherChars.Length; i++)
            {
                cipherChars[i] = cipherChars[i];
            }
        }
    }
}

要将 int 值放入 int 数组中，您可以将其用作 LINQ 选择。例如:

 string fileText = @"C:/Users/Samuel/Documents/Computer_Science/PaDS/caeserShiftEncodedText";

 int [] charactersAsInts = File.ReadAllText(fileText).Select(chr => (int)chr).ToArray();
