ASCII扩展为C#字符串 [英] ASCII Extended in C# string

问题描述

我如何在C#中创建一个字符串以接受不可打印的ASCII扩展字符，例如•，因为当我尝试将•放入字符串中时，它只能给出一个空格或空值.

How do I make a string in C# to accept non printable ASCII extended characters like • , cause when I try to put • in a string it just give a blank space or null.

推荐答案

扩展ASCII只是将8个高位设置为不同值的ASCII.

Extended ASCII is just ASCII with the 8 high bits set to different values.

问题在于，没有任何委员会批准扩展ASCII的标准.那里有很多变体，无法告诉您使用的是什么.

The problem lies in the fact that no commission has ratified a standard for extended ASCII. There are a lot of variants out there and there's no way to tell what you are using.

现在C#使用UTF-16编码，该编码将与您所使用的任何扩展ASCII码不同.

Now C# uses UTF-16 encoding which will be different from whichever extended ASCII you are using.

您将必须找到匹配的Unicode字符并将其显示如下

You will have to find the matching Unicode character and display it as follows

string a ="\u2649"  ; //where 2649 is a the Unicode number
Console.write(a) ;  

或者，您可以找出文件使用的编码方式，并像这样使用 例如.编码Windows-1252:

Alternatively you could find out which encoding your files use and use it like so eg. encoding Windows-1252:

Encoding encoding = Encoding.GetEncoding(1252);

和UTF-16

Encoding enc = new UnicodeEncoding(false, true, true);

并使用

 Encoding.Convert (Encoding, Encoding, Byte[], Int32, Int32)
