我在C＃中的起始学生，我无法找到以下问题的答案：C＃分配，二进制文件类型
“写一个程序，打开一个文本文件，并保存在单独的高，低4位半字节和二进制文件编写一个程序来完成reerse，即从二进制文件中读取两个字节，将它们组合起来并将它们写为文本文件“
我可以读取代码，并理解它。但是因为我是这个领域的新手，所以我很难完全靠自己完成。
我已经编写了用于打开.txt文件并将其保存为.txt文件的代码。

我真的很高兴在这件事上给了一些帮助！ :)
在此先感谢！
的问题是不完整的，一些重要的话是失踪。二进制输出将包含字节。每个字节在一个单独的字节中？作为最不重要的半字节？ – DrKoch
所以你已经完成了所有不属于任务的内容，并且想知道如何完成这项任务？因为在任务中我没有看到有关用户界面的任何信息（并且当我做这些任务时，我通常会创建命令行工具来执行这些任务） – xanatos
这不会帮助向我们展示内衬：'MessageBox.Show（ “STAAAAAAAAAAAAAAAHHHHHPPPPPPPP！”）;'请删除这个** LOUD NOISE ** – DrKoch
