Character Escape Sequence

• An escape character sequence is an instruction to the runtime to insert a special character that will affect the output of your string. In C#, the escape character sequence begins with a backslash \ followed by the character you're escaping.

\ - use case -> Console.WriteLine("Hello \"World\"!"); -> Hello "World"!
-> backslash \ followed by the character you're escaping
\n - new line
\t - new tab big space

Verbatim string literal

• will keep all whitespace and characters without the need to escape the backslash.

Console.WriteLine(@"    c:\source\repos    
        (this is where your code goes)");

Output
c:\source\repos    
        (this is where your code goes)

Unicode escape characters

• add encoded characters in literal strings using the \u escape sequence, then a four-character code representing some character in Unicode (UTF-16).

Console.WriteLine("\u3053\u3093\u306B\u3061\u306F World!");
Output -> // Kon'nichiwa World

String Interpolation

int version = 11;
string updateText = "Update to Windows";
Console.WriteLine($"{updateText} {version}!");

Outpt:
Update to Windows 11!
