'\' is an escape character. Use Console.WriteLine("\\") to get the desired output. You can also use @ like Console.WriteLine(@"Your_Content") and the content will be automatically escaped.

It's a escape character, use Console.Write("\\"). These are used in escape sequences, here is a list of them:

  • \a → Bell (alert)
  • \b → Backspace
  • \f → Formfeed
  • \n → New line
  • \r → Carriage return
  • \t → Horizontal tab
  • \v → Vertical tab
  • \' → Single quotation mark
  • \" → Double quotation mark
  • \\ → Backslash (You have to use this one)
  • \? → Literal question mark
  • \ ooo → ASCII character in octal notation
  • \x hh → ASCII character in hexadecimal notation
  • \x hhhh → Unicode character in hexadecimal notation if this escape sequence is used in a wide-character constant or a Unicode string literal.
  • \uxxxx → Unicode escape sequence for character with hex value xxxx
  • \xn[n][n][n]→ Unicode escape sequence for character with hex value nnnn (variable length version of \uxxxx)
  • \Uxxxxxxxx → Unicode escape sequence for character with hex value xxxxxxxx (for generating surrogates)

You can also use Console.WriteLine(@"\");, see this for an expanation.

\ is used as an escape character inside strings. In order to output the \ itself you need to escape it by doubling it up, or use a string literal by prefixing your string with @.

Either of these will work.

Console.WriteLine("\\");

Console.WriteLine(@"\");
