How do I write the escape char '\' to code

How to escape the character \ in C#?

回答1:

You just need to escape it:

char c = '\\';

Or you could use the Unicode escape sequence:

char c = '\u005c';

See my article on strings for all the various escape sequences available in string/character literals.

回答2:

You can escape a backslash using a backslash.

//String
string backslash = "\\";

//Character
char backslash = '\\';

or

You can use the string literal.

string backslash = @"\";
char backslash = @"\"[0];

回答3:

use double backlash like so "\"

"\\"

cause an escape

回答4:

If you want to output it in a string, you can write "\\" or as a character, you can write '\\'.

回答5:

Escape it: "\\"

or use the verbatim syntax: @"\"

回答6:

Double escape it. Escape escape = no escape! \\
