You can use backslash either way   string str    He said to me    Hello World    How are you      It prints   He said to me   Hello World   How are you    which is exactly same prints with   string str     He said to me    Hello World    How are you      Here is a DEMO     is still part of your string   Check out Escape Sequences and String literals from MSDN

In C  you can use the backslash to put special characters to your string  For example  to put    you need to write     There are a lot of characters that you write using the backslash  Backslash with a number     000 null  010 backspace  011 horizontal tab  012 new line  015 carriage return  032 substitute  042 double quote  047 single quote  134 backslash  140 grave accent   Backslash with othe character    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    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  For example  WCHAR f   L  x4e00  or WCHAR b     L The Chinese character for one is  x4e00

One solution  is to add support to the csharp language so that  quot  quot  isn t the only scheme used for strings  For another string terminator to the C  language - I m a fan of backtick in ES6  string test    He said to me   quot Hello World quot   How are you     But also  the doubling idea in Markdown might be better  string test    quot  quot He said to me   quot Hello World quot   How are you  quot  quot    The code does not work at the date of this post  This post is a solution where the visitors to this Q amp A jump onto this csharplank ticket for C  and upvote it - https   github com dotnet csharplang discussions 3917

No   Either use verbatim string literals as you have  or escape the   using backslash   string test    He said to me    Hello World     How are you      The string has not changed in either case - there is a single escaped   in it  This is just a way to tell C  that the character is part of the string and not a string terminator

User · Answer

You re misunderstanding escaping   The extra   characters are part of the string literal  they are interpreted by the compiler as a single     The actual value of your string is still He said to me    Hello World  How are you    as you ll see if you print it at runtime
