推荐答案

您指的是所谓的扩展" ascii，它是一组将常规7位ascii扩展1位(有时甚至更多)的编码. iso-8859-1是一种这样的编码，它似乎是您所需要的一种.因此，要获得您期望的结果，请执行以下操作:

You are refering to so called "extended" ascii, which is group of encodings extending regular 7-bit ascii by 1 bit (sometimes even more). One such encoding is iso-8859-1, which seems to be the one you need. So to get result you expect, do:

asciiBytes = Encoding.GetEncoding("iso-8859-1").GetBytes(as_pass);
