如何在C#中将ASCII字符转换为字节 [英] How to convert ascii char to byte in c#

问题描述

你好，我从ASCII转换为字节有问题.我有代码:

Hello I have a problem with conversion from ASCII to Byte. I have the code:

byte M = Convert.ToByte('M');

但是我不想从UTF-16转换为字节.在我的问题中，我想发送带ASCII码的字节.

but this converts from UTF-16 to byte with I don't want. In my problem I would like to send bytes with ASCII codes.

推荐答案

只需告诉编译器将char转换为字节:

just tell the compiler to convert the char to byte:

 byte b = (byte)'M';

或(请参阅上面的Adwaenyth的评论)

or (see comment of Adwaenyth above)

byte b = Encoding.ASCII.GetBytes("M")[0];

b的值为77(M为ASCII).

b will have the value 77 (ASCII for M).

或输入字符串:

byte[] b2 = Encoding.ASCII.GetBytes("text");
