Question

所以我想要在C＃中重新创建一些Python源代码。代码是关于读取和解密二进制文件。我已经在现有文件上测试了该函数，它运行时没有错误;虽然结果字符串没有乱码或任何东西，但它似乎对我没用。但这超出了这个问题的范围，我只想知道我是否已将函数正确地转换为C＃，因此它与Python中的相同。

Python代码：

    filename = os.path.basename(path_and_filename)
    key = 0
    for char in filename:
        key = key + ord(char)
    f = open(path_and_filename, 'rb')
    results = ''
    tick = 1
    while True:
        byte = f.read(2)
        if byte:
            if tick:
                key = key + 2
            else:
                key = key - 2
            tick = not tick
            res = struct.unpack('h', byte)[0] ^ key
            results = results + chr(res)
            continue
        break
    f.close()
    return results

path_and_filename是加密文件的绝对路径。这是我写的C＃代码：

        string path = @"C:\Program Files (x86)\Steam\steamapps\common\SolForge\data\released\c28556fb686c8d07066419601a2bdd83\Game_Keywords.dat";
        char[] chars = "c28556fb686c8d07066419601a2bdd83".ToCharArray();
        int key = 0;
        foreach (char c in chars)
        {
            key += c;
        }
        StringBuilder builder = new StringBuilder();


        using (FileStream file = new FileStream(path, FileMode.Open))
        {
            bool tick = true;

            while (true)
            {
                int i = file.ReadByte();
                if (i == -1)
                    break;
                if (tick)
                    key += 2;
                else
                    key -= 2;
                tick = !tick;


                //The next 2 lines are for parsing the short, equivalent(?) to struct.unpack('h', byte)
                i <<= 8;
                i += file.ReadByte();

                i ^= key;
                byte b = (byte)i;
                char c = (char)b;
                builder.Append(c);
            }
        }
        string result = builder.ToString();

别介意代码的肮脏。这两个片段是否会将相同的输出提供给某个输入？

这些C＃和Python代码片段在功能上是否完全相同？
