C # translatable characters

C # Escape characters:

• A special character constant
• Start with a backslash "\" followed by one or several characters
• Have a specific meaning, different from the original meaning of the character, it is called "escape" character.
• It is used primarily to denote control codes that are not easily represented by ordinary characters.
• Its role is to eliminate the original meaning of the character immediately following it
• Use a combination of some ordinary characters to replace some special characters, because their combination changes the meaning of the original character representation, so called "escape"
• A character that cannot be seen by a visible character, such as ' \ n ' means a newline

Commonly used escape characters and their meanings:

\ ' Single quotation mark

\ "Double quotation marks

\ \ counter Slash

Air

\a Warning (beep-generated)

The Meaning of @:

@ in C # for forced non-escaped symbols, the escape character format ("\" + "one character") in it loses its function as a normal string processing

String str1 = "abc\n";     Here \ nthe default escape is a newline character string str2 = @ "abc\n";    This is not escaped here as a newline character, but as a normal string "\ n" (a string consisting of characters ' \ ' and ' n '), which is equivalent to str2 = "abc\\n";

The following two forms of equivalence

String FilePath = "C:\\users\\eniac\\desktop\\matrix\\a.txt";//each \ \ is an escape character that represents a single backslash ' \ ' string filePath = @ "C:\Users\　　 Eniac\desktop\matrix\a.txt "; Do not escape
