This method relies on the FileStream class to buffer the input and output files appropriately, so that the code can work byte by byte to perform the necessary processing.

该方法依靠 FileStream 类来适当地缓冲输入和输出文件，以便代码可以逐个字节地执行必要的处理。

Byte arrays are limited in length to 75 percent of MAX_VALUE_LENGTH because byte arrays are stored by encoding them as strings.

字节数组限制为MAX_VALUE_LENGTH长度75%，因为字节数组是通过编码为字符串存储的。

RC4 begins by creating a 256-byte "s" byte array and populating it with 0 to 255. You then iterate over the array by mixing in bytes from the key.

RC4从创建一个256字节的数组“S”开始，并从0到255对其进行填充。

So it does that for us so that you can get away with just knowing the address of the first byte and it will make sure that you know when to stop by including the special value so, in fact, get the string if you type in a three-letter word, we allocate four bytes no matter what because we need an additional byte 0 for this special sentinel value back slash zero at the very end.

它为我们做了这些事情，这样我们就可以,通过第一个字节的地址,它还可以通过包含一个特殊的值,来保证在哪里停止，如果你输入了一个三个字母的单词,就可以获得那个字符串，不管怎样，我们分配四个字节,因为我们在末端需要一个额外的字节,来保存这个特殊的标志值--反斜杠。

I store in s1 the address of the first byte that the user typed in and by the way that first bite happens to live in this new place called the heap and that's the only update to the story thus far.

我在s1中存储的是用户输入的字符串的首地址,这样第一个字节存储在这块,新的堆的地方,这个是唯一的修正。
