How to escape the character \ in C#?

5For future reference, when searching in Google, the magic words for this sorta thing are "escape" or "escaping" :)Umar F Khawaja– Umar F Khawaja2013-04-02 15:35:17 +00:00Commented Apr 2, 2013 at 15:35

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.

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];

He didn't say he wanted it as a char, he said he wanted to know how to write it.

@Romoku: Well, the question talks about char rather than string, and uses single quotes in the example. I agree it could be clearer though.

@JonSkeet Well I edited in the char to provide a complete answer.

@Romoku: You might want to get rid of the
@'\' bit as it's invalid. I had a brain-fart when I included it. Also, the @ makes it a verbatim string literal, as opposed to a plain string literal without - both are string literals.Dustin Kingen
@JonSkeet I figured
@"\"[0] was close enough. Probably not very efficient.use double backlash like so "\"
"\\"
cause an escape

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

Escape it: "\\"
or use the verbatim syntax: @"\"

The
@ is for verbatim, not global escape. Verbatim strings contain even the newline characters, etc.Double escape it. Escape escape = no escape! \\

To insert a backslash, you need to type it twice:
string myPath = "C:\\Users\\YourUser\\Desktop\\YourFile.txt";
The string myPath should now contain: C:\Users\YourUser\Desktop\YourFile.txt
