Listing an ASCII table is saved everywhere !, One ascii copy The table is from. Here Extended code table: Among the following characters, the smallest ASCII value is () A, Space B, 0 C, A D, Minimum spaceThe largest one is.Common ASCII code size rules: 0 ~ 9 1) numbers are smaller than letters. For example, "7" 2) T

In fact, it is very simple to use the ASCIIEncoding class to convert each other, below I provide two ways to look at the big one1.

ASCII, American Standard Code for information interchange reads like "Aspen Key," which defines the English letters or the same results and meanings that are represented by 128 numbers from 0 to 127. Since only 7 bits (bit) are used to represent numbers from 0 to 127, most computers use 8 bits to access a character set (character set), so numbers from 128 to 255 can be used to represent another set of 128 symbols, called extended

ASCII, American Standard Code for Information Interchange reads like "astkey" and defines the English letters or the same result and meaning represented by the 127 numbers ranging from 0 to one hundred and twenty-eight. Because only seven digits (bit) can be used to represent numbers from 0 to 127, most computers use eight digits to access the character set (character set ), therefore, numbers between 128 and 255 can be used to represent another group

one byte (eight binary digits), and its highest bit (B7) is used as the parity bit. The so-called parity check refers to a method used to check for errors during code transfer. It is generally divided into two types: Odd checksum and even verification. Odd check rules: correct code must contain an odd number of 1 bytes. If the number is not an odd number, 1 is added to the highest bit B7. Even check rules: correct code: the number of 1 in a byte must be an even number. If the number is not an e
