生成ASCII并创建文件 [英] Generating ASCII and Creating a File

问题描述

你好，

我试图通过FIRST输入十进制值生成ASCII字符，然后创建一个外部文件来保存字符 。有人可以告诉我如何做到这一点。我对Filestream Class有很多问题，一个错误接着另一个。这非常复杂。

Hello,
I am trying to generate ASCII Characters by FIRST entering the decimal value and then creating a external file to save the Characters. Can someone please show me how to do this. I having many problems with the Filestream Class, one error after the other. This is very complicated.

推荐答案

这一点都不复杂！ ：笑：



ASCII只是字节值，根据字符集解释为字符： http://www.charstable.com/_site_media/ascii/chars-table-landscape.jpg [ ^ ]

因此，如果您的用户（或您的代码） ）为每个字符输入十进制值，您只需将其转换为字节值，将其插入字节集合并将这些值直接写入您的文件。

It's not at all complicated! :laugh:

ASCII is just byte values which are interpreted as characters according to a character set: http://www.charstable.com/_site_media/ascii/chars-table-landscape.jpg[^]
So if your user (or your code) is entering decimal values for each character, all you have to do is convert that to a byte value, insert it into a collection of bytes and write those values direct to your file.

byte[] data = new byte[] {72, 101, 108, 108, 111, 13, 10};
File.WriteAllBytes(@"D:\Temp\MyFile.txt", data);

将文本Hello和换行符写入文件......

Will write the text "Hello" and a newline to the file...
