Both answers already posted are correct. In C# a normal double-quoted string treats \ as the escape introducer, so a lone backslash inside quotes will be parsed as part of an escape and will confuse the compiler. pointed to the verbatim-literal approach and showed the escaped-backslash approach; both produce the same runtime value (a single backslash).

Which to pick

  • Use a verbatim literal (the @ form) when the text contains many backslashes (file paths, Windows registry keys, many regexes) — it keeps the string readable. Note that in a verbatim literal embedded double quotes are written by doubling them.
  • Use escaped backslashes in a normal literal if the string is short or you prefer the conventional style.

Examples (not shown earlier)

  • Doubling quotes inside a verbatim literal:
    var quoted = @"She said ""Hello"" to everyone.";
  • Combining interpolation and verbatim for readable paths:
    var path = $@"C:\Users\{userName}\Documents\notes.txt";

Cautions and tips

  • For regular expressions prefer verbatim literals so the pattern uses single backslashes (the regex engine expects \d, not \\d).
  • If you need a string that literally contains a single double quote, use "" inside a verbatim literal.
  • The order of $ and @ does not matter for interpolated verbatim strings ($@"..." and @$"..." both work).

Official reference

  • Verbatim string literals and escape sequences are documented by Microsoft: and .
