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

Question

How to escape the character \ in C#?

Answer 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.

Answer 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];
